- - - - - This section of documentation covers how we approach and think about evaluation in LangChain. -Both evaluation of internal chains/agents, but also how we would recommend people building on top of LangChain approach evaluation. - - - - - - The Problem - [#](#the-problem "Permalink to this headline") -------------------------------------------------------------- - - - - It can be really hard to evaluate LangChain chains and agents. -There are two main reasons for this: - - - - -**# 1: Lack of data** - - - - - You generally don’t have a ton of data to evaluate your chains/agents over before starting a project. -This is usually because Large Language Models (the core of most chains/agents) are terrific few-shot and zero shot learners, -meaning you are almost always able to get started on a particular task (text-to-SQL, question answering, etc) without -a large dataset of examples. -This is in stark contrast to traditional machine learning where you had to first collect a bunch of datapoints -before even getting started using a model. - - - - -**# 2: Lack of metrics** - - - - - Most chains/agents are performing tasks for which there are not very good metrics to evaluate performance. -For example, one of the most common use cases is generating text of some form. -Evaluating generated text is much more complicated than evaluating a classification prediction, or a numeric prediction. - - - - - - - The Solution - [#](#the-solution "Permalink to this headline") ---------------------------------------------------------------- - - - - LangChain attempts to tackle both of those issues. -What we have so far are initial passes at solutions - we do not think we have a perfect solution. -So we very much welcome feedback, contributions, integrations, and thoughts on this. - - - - - Here is what we have for each problem so far: - - - - -**# 1: Lack of data** - - - - - We have started - [LangChainDatasets](https://huggingface.co/LangChainDatasets) - a Community space on Hugging Face. -We intend this to be a collection of open source datasets for evaluating common chains and agents. -We have contributed five datasets of our own to start, but we highly intend this to be a community effort. -In order to contribute a dataset, you simply need to join the community and then you will be able to upload datasets. - - - - - We’re also aiming to make it as easy as possible for people to create their own datasets. -As a first pass at this, we’ve added a QAGenerationChain, which given a document comes up -with question-answer pairs that can be used to evaluate question-answering tasks over that document down the line. -See - [this notebook](./evaluation/qa_generation) - for an example of how to use this chain. - - - - -**# 2: Lack of metrics** - - - - - We have two solutions to the lack of metrics. - - - - - The first solution is to use no metrics, and rather just rely on looking at results by eye to get a sense for how the chain/agent is performing. -To assist in this, we have developed (and will continue to develop) - [tracing](../tracing) - , a UI-based visualizer of your chain and agent runs. - - - - - The second solution we recommend is to use Language Models themselves to evaluate outputs. -For this we have a few different chains and prompts aimed at tackling this issue. -

It has been serialized in Shueisha\'s shōnen manga magazine Weekly Shōnen Jump since March 1998, although the manga has frequently gone on extended hiatuses since 2006. Its chapters have been collected in 37 tankōbon volumes as of November 2022. The story focuses on a young boy named Gon Freecss who discovers that his father, who left him at a young age, is actually a world-renowned Hunter, a licensed professional who specializes in fantastical pursuits such as locating rare or unidentified animal species, treasure hunting, surveying unexplored enclaves, or hunting down lawless individuals. Gon departs on a journey to become a Hunter and eventually find his father. Along the way, Gon meets various other Hunters and encounters the paranormal.\nHunter × Hunter was adapted into a 62-episode anime television series produced by Nippon Animation and directed by Kazuhiro Furuhashi, which ran on Fuji Television from October 1999 to March 2001. Three separate original video animations (OVAs) totaling 30 episodes were subsequently produced by Nippon Animation and released in Japan from 2002 to 2004.

We believe that the most powerful and differentiated applications will not only call out to a language model via an API, but will also:\nBe data-aware: connect a language model to other sources of data\nBe agentic: allow a language model to interact with its environment\nThe LangChain framework is designed with the above principles in mind.\nThis is the Python specific portion of the documentation. For a purely conceptual guide to LangChain, see here. For the JavaScript documentation, see here.\nGetting Started\nCheckout the below guide for a walkthrough of how to get started using LangChain to create an Language Model application.\nGetting Started Documentation\nModules\nThere are several main modules that LangChain provides support for. For each module we provide some examples to get started, how-to guides, reference docs, and conceptual guides. These modules are, in increasing order of complexity:\nModels: The various model types and model integrations LangChain supports.\nPrompts: This includes prompt management, prompt optimization, and prompt serialization.\nMemory: Memory is the concept of persisting state between calls of a chain/agent. LangChain provides a standard interface for memory, a collection of memory implementations, and examples of chains/agents that use memory.\nIndexes: Language models are often more powerful when combined with your own text data - this module covers best practices for doing exactly that.\nChains: Chains go beyond just a single LLM call, and are sequences of calls (whether to an LLM or a different utility). LangChain provides a standard interface for chains, lots of integrations with other tools, and end-to-end chains for common applications.\nAgents: Agents involve an LLM making decisions about which Actions to take, taking that Action, seeing an Observation, and repeating that until done. LangChain provides a standard interface for agents, a selection of agents to choose from, and examples of end to end agents.\nUse Cases\nThe above modules can be used in a variety of ways. LangChain also provides guidance and assistance in this. Below are some of the common use cases LangChain supports.\nPersonal Assistants: The main LangChain use case. Personal assistants need to take actions, remember interactions, and have knowledge about your data.\nQuestion Answering: The second big LangChain use case. Answering questions over specific documents, only utilizing the information in those documents to construct an answer.\nChatbots: Since language models are good at producing text, that makes them ideal for creating chatbots.\nQuerying Tabular Data: If you want to understand how to use LLMs to query data that is stored in a tabular format (csvs, SQL, dataframes, etc) you should read this page.\nInteracting with APIs: Enabling LLMs to interact with APIs is extremely powerful in order to give them more up-to-date information and allow them to take actions.\nExtraction: Extract structured information from text.\nSummarization: Summarizing longer documents into shorter, more condensed chunks of information. A type of Data Augmented Generation.\nEvaluation: Generative models are notoriously hard to evaluate with traditional metrics. One new way of evaluating them is using language models themselves to do the evaluation. LangChain provides some prompts/chains for assisting in this.\nReference Docs\nAll of LangChain’s reference documentation, in one place. Full documentation on all methods, classes, installation methods, and integration setups for LangChain.\nReference Documentation\nLangChain Ecosystem\nGuides for how other companies/products can be used with LangChain\nLangChain Ecosystem\nAdditional Resources\nAdditional collection of resources we think may be useful as you develop your application!\nLangChainHub: The LangChainHub is a place to share and explore other prompts, chains, and agents.\nGlossary: A glossary of all related terms, papers, methods, etc. Whether implemented in LangChain or not!\nGallery: A collection of our favorite projects that use LangChain. Useful for finding inspiration or seeing how things were done in other applications.\nDeployments: A collection of instructions, code snippets, and template repositories for deploying LangChain apps.\nTracing: A guide on using tracing in LangChain to visualize the execution of chains and agents.\nModel Laboratory: Experimenting with different prompts, models, and chains is a big part of developing the best possible application. The ModelLaboratory makes it easy to do so.\nDiscord: Join us on our Discord to discuss all things LangChain!\nProduction Support: As you move your LangChains into production, we’d love to offer more comprehensive support.

To this end, the LayoutParser community platform also enables -the sharing of layout pipelines to promote the discussion and reuse of techniques. -For each shared pipeline, it has a dedicated project page, with links to the source -code, documentation, and an outline of the approaches.

The Cayley trick, following the philosophy of Mavlyutov in [7], reduces results known for quasi-smooth hypersurfaces to quasi-smooth intersection subvarieties.

Let L 1 , . . . , L s be line bundles on P d Σ and let π ∶ P ( E ) → P d Σ be the projective space bundle associated to the vector bundle E = L 1 ⊕ ⋯ ⊕ L s . It is known that P ( E ) is a ( d + s − 1 ) -dimensional simplicial toric variety whose fan depends on the degrees of the line bundles and the fan Σ. Furthermore, if the Cox ring, without considering the grading, of P d Σ is C [ x 1 , . . . , x m ] then the Cox ring of P ( E ) is\n\nMoreover for X a quasi-smooth intersection subvariety cut off by f 1 , . . . , f s with deg ( f i ) = [ L i ] we relate the hypersurface Y cut off by F = y 1 f 1 + ⋅ ⋅ ⋅ + y s f s which turns out to be quasi-smooth. For more details see Section 2 in [7].\n\nWe will denote P ( E ) as P d + s − 1 Σ ,X to keep track of its relation with X and P d Σ .\n\nThe following is a key remark.\n\nRemark 4.1 . There is a morphism ι ∶ X → Y ⊂ P d + s − 1 Σ ,X . Moreover every point z ∶ = ( x, y ) ∈ Y with y ≠ 0 has a preimage. Hence for any subvariety W = V ( I W ) ⊂ X ⊂ P d Σ there exists W ′ ⊂ Y ⊂ P d + s − 1 Σ ,X such that π ( W ′ ) = W , i.e., W ′ = { z = ( x, y ) ∣ x ∈ W } .\n\nFor X ⊂ P d Σ a quasi-smooth intersection variety the morphism in cohomology induced by the inclusion i ∗ ∶ H d − s ( P d Σ , C ) → H d − s ( X, C ) is injective by Proposition 1.4 in [7].\n\nDefinition 4.2. The primitive cohomology of H d − s prim ( X ) is the quotient H d − s ( X, C )/ i ∗ ( H d − s ( P d Σ , C )) and H d − s prim ( X, Q ) with rational coefficients.\n\nH d − s ( P d Σ , C ) and H d − s ( X, C ) have pure Hodge structures, and the morphism i ∗ is com- patible with them, so that H d − s prim ( X ) gets a pure Hodge structure.\n\nThe next Proposition is the Cayley proposition.\n\nProposition 4.3. [Proposition 2.3 in [3] ] Let X = X 1 ∩⋅ ⋅ ⋅∩ X s be a quasi-smooth intersec- tion subvariety in P d Σ cut off by homogeneous polynomials f 1 . . . f s . Then for p ≠ d + s − 1 2 , d + s − 3 2\n\nRemark 4.5 . The above isomorphisms are also true with rational coefficients since H ● ( X, C ) = H ● ( X, Q ) ⊗ Q C . See the beginning of Section 7.1 in [10] for more details.\n\nTheorem 5.1. Let Y = { F = y 1 f 1 + ⋯ + y k f k = 0 } ⊂ P 2 k + 1 Σ ,X be the quasi-smooth hypersurface associated to the quasi-smooth intersection surface X = X f 1 ∩ ⋅ ⋅ ⋅ ∩ X f k ⊂ P k + 2 Σ . Then on Y the Hodge conjecture holds.\n\nthe Hodge conjecture holds.\n\nProof. If H k,k prim ( X, Q ) = 0 we are done. So let us assume H k,k prim ( X, Q ) ≠ 0. By the Cayley proposition H k,k prim ( Y, Q ) ≃ H 1 , 1 prim ( X, Q ) and by the ( 1 , 1 ) -Lefschetz theorem for projective\n\ntoric orbifolds there is a non-zero algebraic basis λ C 1 , . . . , λ C n with rational coefficients of H 1 , 1 prim ( X, Q ) , that is, there are n ∶ = h 1 , 1 prim ( X, Q ) algebraic curves C 1 , . . . , C n in X such that under the Poincar´e duality the class in homology [ C i ] goes to λ C i , [ C i ] ↦ λ C i . Recall that the Cox ring of P k + 2 is contained in the Cox ring of P 2 k + 1 Σ ,X without considering the grading. Considering the grading we have that if α ∈ Cl ( P k + 2 Σ ) then ( α, 0 ) ∈ Cl ( P 2 k + 1 Σ ,X ) . So the polynomials defining C i ⊂ P k + 2 Σ can be interpreted in P 2 k + 1 X, Σ but with different degree. Moreover, by Remark 4.1 each C i is contained in Y = { F = y 1 f 1 + ⋯ + y k f k = 0 } and\n\nfurthermore it has codimension k .\n\nClaim: { C i } ni = 1 is a basis of prim ( ) . It is enough to prove that λ C i is different from zero in H k,k prim ( Y, Q ) or equivalently that the cohomology classes { λ C i } ni = 1 do not come from the ambient space. By contradiction, let us assume that there exists a j and C ⊂ P 2 k + 1 Σ ,X such that λ C ∈ H k,k ( P 2 k + 1 Σ ,X , Q ) with i ∗ ( λ C ) = λ C j or in terms of homology there exists a ( k + 2 ) -dimensional algebraic subvariety V ⊂ P 2 k + 1 Σ ,X such that V ∩ Y = C j so they are equal as a homology class of P 2 k + 1 Σ ,X ,i.e., [ V ∩ Y ] = [ C j ] . It is easy to check that π ( V ) ∩ X = C j as a subvariety of P k + 2 Σ where π ∶ ( x, y ) ↦ x . Hence [ π ( V ) ∩ X ] = [ C j ] which is equivalent to say that λ C j comes from P k + 2 Σ which contradicts the choice of [ C j ] .\n\nRemark 5.2 . Into the proof of the previous theorem, the key fact was that on X the Hodge conjecture holds and we translate it to Y by contradiction.

Montoya Instituto de Matem´atica, Estat´ıstica e Computa¸c˜ao Cient´ıfica, In [3] we proved that, under suitable conditions, on a very general codimension s quasi- smooth intersection subvariety X in a projective toric orbifold P d Σ with d + s = 2 ( k + 1 ) the Hodge conjecture holds, that is, every ( p, p ) -cohomology class, under the Poincar´e duality is a rational linear combination of fundamental classes of algebraic subvarieties of X . The proof of the above-mentioned result relies, for p ≠ d + 1 − s , on a Lefschetz Keywords: (1,1)- Lefschetz theorem, Hodge conjecture, toric varieties, complete intersection Email: wmontoya@ime.unicamp.br theorem ([7]) and the Hard Lefschetz theorem for projective orbifolds ([11]). When p = d + 1 − s the proof relies on the Cayley trick, a trick which associates to X a quasi-smooth hypersurface Y in a projective vector bundle, and the Cayley Proposition (4.3) which gives an isomorphism of some primitive cohomologies (4.2) of X and Y . The Cayley trick, following the philosophy of Mavlyutov in [7], reduces results known for quasi-smooth hypersurfaces to quasi-smooth intersection subvarieties. The idea in this paper goes the other way around, we translate some results for quasi-smooth intersection subvarieties to Acknowledgement.

Let M be a free abelian group of rank d , let N = Hom ( M, Z ) , and N R = N ⊗ Z R . if there exist k linearly independent primitive elements e , . . . , e k ∈ N such that σ = { µ e + ⋯ + µ k e k } . • The generators e i are integral if for every i and any nonnegative rational number µ the product µe i is in N only if µ is an integer. • Given two rational simplicial cones σ , σ ′ one says that σ ′ is a face of σ ( σ ′ < σ ) if the set of integral generators of σ ′ is a subset of the set of integral generators of σ . • A finite set Σ = { σ , . . . , σ t } of rational simplicial cones is called a rational simplicial complete d -dimensional fan if: all faces of cones in Σ are in Σ ; if σ, σ ′ ∈ Σ then σ ∩ σ ′ < σ and σ ∩ σ ′ < σ ′ ; N R = σ ∪ ⋅ ⋅ ⋅ ∪ σ t . A rational simplicial complete d -dimensional fan Σ defines a d -dimensional toric variety P d Σ having only orbifold singularities which we assume to be projective. Moreover, T ∶ = N ⊗ Z C ∗ ≃ ( C ∗ ) d is the torus action on P d Σ . We denote by Σ ( i ) the i -dimensional cones For a cone σ ∈ Σ, ˆ σ is the set of 1-dimensional cone in Σ that are not contained in σ and x ˆ σ ∶ = ∏ ρ ∈ ˆ σ x ρ is the associated monomial in S . Definition 2.2. The irrelevant ideal of P d Σ is the monomial ideal B Σ ∶ =< x ˆ σ ∣ σ ∈ Σ > and the zero locus Z ( Σ ) ∶ = V ( B Σ ) in the affine space A d ∶ = Spec ( S ) is the irrelevant locus. Proposition 2.3 (Theorem 5.1.11 [5]) . The toric variety P d Σ is a categorical quotient A d ∖ Z ( Σ ) by the group Hom ( Cl ( Σ ) , C ∗ ) and the group action is induced by the Cl ( Σ ) - grading of S . Now we give a brief introduction to complex orbifolds and we mention the needed theorems for the next section. Namely: de Rham theorem and Dolbeault theorem for complex orbifolds. Definition 2.4. A complex orbifold of complex dimension d is a singular complex space whose singularities are locally isomorphic to quotient singularities C d / G , for finite sub- groups G ⊂ Gl ( d, C ) . Definition 2.5. A differential form on a complex orbifold Z is defined locally at z ∈ Z as a G -invariant differential form on C d where G ⊂ Gl ( d, C ) and Z is locally isomorphic to d Roughly speaking the local geometry of orbifolds reduces to local G -invariant geometry. We have a complex of differential forms ( A ● ( Z ) , d ) and a double complex ( A ● , ● ( Z ) , ∂, ¯ ∂ ) of bigraded differential forms which define the de Rham and the Dolbeault cohomology groups (for a fixed p ∈ N ) respectively: (1,1)-Lefschetz theorem for projective toric orbifolds Definition 3.1. A subvariety X ⊂ P d Σ is quasi-smooth if V ( I X ) ⊂ A #Σ ( 1 ) is smooth outside Example 3.2 . Quasi-smooth hypersurfaces or more generally quasi-smooth intersection sub- Example 3.2 . Quasi-smooth hypersurfaces or more generally quasi-smooth intersection sub- varieties are quasi-smooth subvarieties (see [2] or [7] for more details). Remark 3.3 . Quasi-smooth subvarieties are suborbifolds of P d Σ in the sense of Satake in [8]. Intuitively speaking they are subvarieties whose only singularities come from the ambient Proof. From the exponential short exact sequence we have a long exact sequence in cohomology H 1 (O ∗ X ) → H 2 ( X, Z ) → H 2 (O X ) ≃ H 0 , 2 ( X ) where the last isomorphisms is due to Steenbrink in [9]. Now, it is enough to prove the commutativity of the next diagram where the last isomorphisms is due to Steenbrink in [9]. Now, H 2 ( X, Z ) / / H 2 ( X, O X ) ≃ Dolbeault H 2 ( X, C ) deRham ≃ H 2 dR ( X, C ) / / H 0 , 2 ¯ ∂ ( X ) of the proof follows as the ( 1 , 1 ) -Lefschetz theorem in [6]. Remark 3.5 . For k = 1 and P d Σ as the projective space, we recover the classical ( 1 , 1 ) - Lefschetz theorem. By the Hard Lefschetz Theorem for projective orbifolds (see [11] for details) we By the Hard Lefschetz Theorem for projective orbifolds (see [11] for details) we get an isomorphism of cohomologies : given by the Lefschetz morphism and since it is a morphism of Hodge structures, we have: H 1 , 1 ( X, Q ) ≃ H dim X − 1 , dim X − 1 ( X, Q ) Corollary 3.6. If the dimension of X is 1 , 2 or 3 . The Hodge conjecture holds on X Proof. If the dim C X = 1 the result is clear by the Hard Lefschetz theorem for projective orbifolds. The dimension 2 and 3 cases are covered by Theorem 3.5 and the Hard Lefschetz. Cayley trick and Cayley proposition The Cayley trick is a way to associate to a quasi-smooth intersection subvariety a quasi- smooth hypersurface. Let L 1 , . . . , L s be line bundles on P d Σ and let π ∶ P ( E ) → P d Σ be the projective space bundle associated to the vector bundle E = L 1 ⊕ ⋯ ⊕ L s . It is known that P ( E ) is a ( d + s − 1 ) -dimensional simplicial toric variety whose fan depends on the degrees of the line bundles and the fan Σ. Furthermore, if the Cox ring, without considering the grading, of P d Σ is C [ x 1 , . . . , x m ] then the Cox ring of P ( E ) is Moreover for X a quasi-smooth intersection subvariety cut off by f 1 , . . . , f s with deg ( f i ) = [ L i ] we relate the hypersurface Y cut off by F = y 1 f 1 + ⋅ ⋅ ⋅ + y s f s which turns out to be quasi-smooth. For more details see Section 2 in [7]. We will denote P ( E ) as P d + s − 1 Σ ,X to keep track of its relation with X and P d Σ . The following is a key remark. Remark 4.1 . There is a morphism ι ∶ X → Y ⊂ P d + s − 1 Σ ,X . Moreover every point z ∶ = ( x, y ) ∈ Y with y ≠ 0 has a preimage. Hence for any subvariety W = V ( I W ) ⊂ X ⊂ P d Σ there exists W ′ ⊂ Y ⊂ P d + s − 1 Σ ,X such that π ( W ′ ) = W , i.e., W ′ = { z = ( x, y ) ∣ x ∈ W } . For X ⊂ P d Σ a quasi-smooth intersection variety the morphism in cohomology induced by the inclusion i ∗ ∶ H d − s ( P d Σ , C ) → H d − s ( X, C ) is injective by Proposition 1.4 in [7]. Definition 4.2. The primitive cohomology of H d − s prim ( X ) is the quotient H d − s ( X, C )/ i ∗ ( H d − s ( P d Σ , C )) and H d − s prim ( X, Q ) with rational coefficients. H d − s ( P d Σ , C ) and H d − s ( X, C ) have pure Hodge structures, and the morphism i ∗ is com- patible with them, so that H d − s prim ( X ) gets a pure Hodge structure. The next Proposition is the Cayley proposition. Proposition 4.3. [Proposition 2.3 in [3] ] Let X = X 1 ∩⋅ ⋅ ⋅∩ X s be a quasi-smooth intersec- tion subvariety in P d Σ cut off by homogeneous polynomials f 1 . . . f s . Then for p ≠ d + s − 1 2 , d + s − 3 2 Remark 4.5 . The above isomorphisms are also true with rational coefficients since H ● ( X, C ) = H ● ( X, Q ) ⊗ Q C . See the beginning of Section 7.1 in [10] for more details. Theorem 5.1. Let Y = { F = y 1 f 1 + ⋯ + y k f k = 0 } ⊂ P 2 k + 1 Σ ,X be the quasi-smooth hypersurface associated to the quasi-smooth intersection surface X = X f 1 ∩ ⋅ ⋅ ⋅ ∩ X f k ⊂ P k + 2 Σ . Then on Y the Hodge conjecture holds. the Hodge conjecture holds. Proof. If H k,k prim ( X, Q ) = 0 we are done. So let us assume H k,k prim ( X, Q ) ≠ 0. By the Cayley proposition H k,k prim ( Y, Q ) ≃ H 1 , 1 prim ( X, Q ) and by the ( 1 , 1 ) -Lefschetz theorem for projective toric orbifolds there is a non-zero algebraic basis λ C 1 , . . . , λ C n with rational coefficients of H 1 , 1 prim ( X, Q ) , that is, there are n ∶ = h 1 , 1 prim ( X, Q ) algebraic curves C 1 , . . . , C n in X such that under the Poincar´e duality the class in homology [ C i ] goes to λ C i , [ C i ] ↦ λ C i . Recall that the Cox ring of P k + 2 is contained in the Cox ring of P 2 k + 1 Σ ,X without considering the grading. Considering the grading we have that if α ∈ Cl ( P k + 2 Σ ) then ( α, 0 ) ∈ Cl ( P 2 k + 1 Σ ,X ) . So the polynomials defining C i ⊂ P k + 2 Σ can be interpreted in P 2 k + 1 X, Σ but with different degree. Moreover, by Remark 4.1 each C i is contained in Y = { F = y 1 f 1 + ⋯ + y k f k = 0 } and furthermore it has codimension k . Claim: { C i } ni = 1 is a basis of prim ( ) . It is enough to prove that λ C i is different from zero in H k,k prim ( Y, Q ) or equivalently that the cohomology classes { λ C i } ni = 1 do not come from the ambient space. By contradiction, let us assume that there exists a j and C ⊂ P 2 k + 1 Σ ,X such that λ C ∈ H k,k ( P 2 k + 1 Σ ,X , Q ) with i ∗ ( λ C ) = λ C j or in terms of homology there exists a ( k + 2 ) -dimensional algebraic subvariety V ⊂ P 2 k + 1 Σ ,X such that V ∩ Y = C j so they are equal as a homology class of P 2 k + 1 Σ ,X ,i.e., [ V ∩ Y ] = [ C j ] . It is easy to check that π ( V ) ∩ X = C j as a subvariety of P k + 2 Σ where π ∶ ( x, y ) ↦ x . Hence [ π ( V ) ∩ X ] = [ C j ] which is equivalent to say that λ C j comes from P k + 2 Σ which contradicts the choice of [ C j ] . Remark 5.2 . Into the proof of the previous theorem, the key fact was that on X the Hodge conjecture holds and we translate it to Y by contradiction. So, using an analogous argument we have: argument we have: Proposition 5.3. Let Y = { F = y 1 f s +⋯+ y s f s = 0 } ⊂ P 2 k + 1 Σ ,X be the quasi-smooth hypersurface associated to a quasi-smooth intersection subvariety X = X f 1 ∩ ⋅ ⋅ ⋅ ∩ X f s ⊂ P d Σ such that d + s = 2 ( k + 1 ) . If the Hodge conjecture holds on X then it holds as well on Y . Corollary 5.4. If the dimension of Y is 2 s − 1 , 2 s or 2 s + 1 then the Hodge conjecture holds on Y . Proof.

Recent advances in document image analysis (DIA) have been\nprimarily driven by the application of neural networks. Ideally, research\noutcomes could be easily deployed in production and extended for further\ninvestigation. However, various factors like loosely organized codebases\nand sophisticated model configurations complicate the easy reuse of im-\nportant innovations by a wide audience. Though there have been on-going\nefforts to improve reusability and simplify deep learning (DL) model\ndevelopment in disciplines like natural language processing and computer\nvision, none of them are optimized for challenges in the domain of DIA.\nThis represents a major gap in the existing toolkit, as DIA is central to\nacademic research across a wide range of disciplines in the social sciences\nand humanities. This paper introduces LayoutParser, an open-source\nlibrary for streamlining the usage of DL in DIA research and applica-\ntions. The core LayoutParser library comes with a set of simple and\nintuitive interfaces for applying and customizing DL models for layout de-\ntection, character recognition, and many other document processing tasks.\nTo promote extensibility, LayoutParser also incorporates a community\nplatform for sharing both pre-trained models and full document digiti-\nzation pipelines. We demonstrate that LayoutParser is helpful for both\nlightweight and large-scale digitization pipelines in real-word use cases.\nThe library is publicly available at https://layout-parser.github.io.\nKeywords: Document Image Analysis · Deep Learning · Layout Analysis\n· Character Recognition · Open Source library · Toolkit.\n1\nIntroduction\nDeep Learning(DL)-based approaches are the state-of-the-art for a wide range of\ndocument image analysis (DIA) tasks including document image classification [11,\narXiv:2103.15348v2 [cs.CV] 21 Jun 2021\n', lookup_str='', metadata={'file_path': 'example_data/layout-parser-paper.pdf', 'page_number': 1, 'total_pages': 16, 'format': 'PDF 1.5', 'title': '', 'author': '', 'subject': '', 'keywords': '', 'creator': 'LaTeX with hyperref', 'producer': 'pdfTeX-1.40.21', 'creationDate': 'D:20210622012710Z', 'modDate': 'D:20210622012710Z', 'trapped': '', 'encryption': None}, lookup_index=0) ``` +此外，您可以将[PyMuPDF文档](https://pymupdf.readthedocs.io/en/latest/app1#plain-text/)中的任何选项作为关键字参数传递给`load`调用，并将其传递给`get_text()`调用。 +PyPDF目录[#](#pypdf-directory "链接到此标题的永久链接") +------------------------------------------ - - - - Additionally, you can pass along any of the options from the - [PyMuPDF documentation](https://pymupdf.readthedocs.io/en/latest/app1#plain-text/) - as keyword arguments in the - `load` - call, and it will be pass along to the - `get_text()` - call. - - - - - - - PyPDF Directory - [#](#pypdf-directory "Permalink to this headline") ---------------------------------------------------------------------- - - - - Load PDFs from directory - - - - - - - +从目录中加载PDF ``` from langchain.document_loaders import PyPDFDirectoryLoader ``` - - - - - - - - - ``` loader = PyPDFDirectoryLoader("example_data/") ``` - - - - - - - - - ``` docs = loader.load() ``` - - - - - - - diff --git a/pages/modules/indexes/document_loaders/examples/powerpoint.md b/pages/modules/indexes/document_loaders/examples/powerpoint.md index 98d8888..7d6b939 100644 --- a/pages/modules/indexes/document_loaders/examples/powerpoint.md +++ b/pages/modules/indexes/document_loaders/examples/powerpoint.md @@ -1,152 +1,18 @@ - - - - PowerPoint - [#](#powerpoint "Permalink to this headline") +PowerPoint =========================================================== +本文介绍如何将PowerPoint文档加载到我们可以在下游使用的文档格式中。 - - This covers how to load PowerPoint documents into a document format that we can use downstream. - - - - - - - +用法： ``` from langchain.document_loaders import UnstructuredPowerPointLoader - -``` - - - - - - - - - - -``` loader = UnstructuredPowerPointLoader("example_data/fake-power-point.pptx") - -``` - - - - - - - - - - -``` -data = loader.load() - -``` - - - - - - - - - - -``` -data - -``` - - - - - - - - -``` -[Document(page_content='Adding a Bullet Slide\n\nFind the bullet slide layout\n\nUse _TextFrame.text for first bullet\n\nUse _TextFrame.add_paragraph() for subsequent bullets\n\nHere is a lot of text!\n\nHere is some text in a text box!', lookup_str='', metadata={'source': 'example_data/fake-power-point.pptx'}, lookup_index=0)] - -``` - - - - - - - - Retain Elements - [#](#retain-elements "Permalink to this headline") ---------------------------------------------------------------------- - - - - Under the hood, Unstructured creates different “elements” for different chunks of text.

As they are walking, they come across a mysterious figure, who tells them that their love will be tested in the near future. The figure then tells the couple that the sun will soon set, and with it, a tragedy will strike. If Jack and Sarah can stay together and pass the test, they will be granted everlasting love.

And with an unwavering resolve that freedom will always triumph over tyranny. Six days ago, Russia’s Vladimir Putin sought to shake the foundations of the free world thinking he could make it bend to his menacing ways. But he badly miscalculated. He thought he could roll into Ukraine and the world would roll over. Instead he met a wall of strength he never imagined. He met the Ukrainian people.

In this lesson, we will look at the += operator in Python and see how it works with several simple examples.. The operator ‘+=’ is a shorthand for the addition assignment operator.It adds two values and assigns the sum to a variable (left operand). W3Schools offers free online tutorials, references and exercises in all the major languages of the web. Covering popular subjects like HTML, CSS, JavaScript, Python, SQL, Java, and many, many more. This tutorial introduces the reader informally to the basic concepts and features of the Python language and system. It helps to have a Python interpreter handy for hands-on experience, but all examples are self-contained, so the tutorial can be read off-line as well.

It has been serialized in Shueisha\'s shōnen manga magazine Weekly Shōnen Jump since March 1998, although the manga has frequently gone on extended hiatuses since 2006. Its chapters have been collected in 37 tankōbon volumes as of November 2022. The story focuses on a young boy named Gon Freecss who discovers that his father, who left him at a young age, is actually a world-renowned Hunter, a licensed professional who specializes in fantastical pursuits such as locating rare or unidentified animal species, treasure hunting, surveying unexplored enclaves, or hunting down lawless individuals. Gon departs on a journey to become a Hunter and eventually find his father. Along the way, Gon meets various other Hunters and encounters the paranormal.\nHunter × Hunter was adapted into a 62-episode anime television series produced by Nippon Animation and directed by Kazuhiro Furuhashi, which ran on Fuji Television from October 1999 to March 2001. Three separate original video animations (OVAs) totaling 30 episodes were subsequently produced by Nippon Animation and released in Japan from 2002 to 2004. A second anime television series by Madhouse aired on Nippon Television from October 2011 to September 2014, totaling 148 episodes, with two animated theatrical films released in 2013. There are also numerous audio albums, video games, musicals, and other media based on Hunter × Hunter.\nThe manga has been translated into English and released in North America by Viz Media since April 2005. Both television series have been also licensed by Viz Media, with the first series having aired on the Funimation Channel in 2009 and the second series broadcast on Adult Swim\'s Toonami programming block from April 2016 to June 2019.\nHunter × Hunter has been a huge critical and financial success and has become one of the best-selling manga series of all time, having over 84 million copies in circulation by July 2022. Page: Hunter × Hunter (2011 TV series)\nSummary: Hunter × Hunter is an anime television series that aired from 2011 to 2014 based on Yoshihiro Togashi\'s manga series Hunter × Hunter. The story begins with a young boy named Gon Freecss, who one day discovers that the father who he thought was dead, is in fact alive and well. He learns that his father, Ging, is a legendary "Hunter", an individual who has proven themselves an elite member of humanity. Despite the fact that Ging left his son with his relatives in order to pursue his own dreams, Gon becomes determined to follow in his father\'s footsteps, pass the rigorous "Hunter Examination", and eventually find his father to become a Hunter in his own right.\nThis new Hunter × Hunter anime was announced on July 24, 2011. It is a complete reboot of the anime adaptation starting from the beginning of the manga, with no connections to the first anime from 1999. Produced by Nippon TV, VAP, Shueisha and Madhouse, the series is directed by Hiroshi Kōjina, with Atsushi Maekawa and Tsutomu Kamishiro handling series composition, Takahiro Yoshimatsu designing the characters and Yoshihisa Hirano composing the music. Instead of having the old cast reprise their roles for the new adaptation, the series features an entirely new cast to voice the characters. The new series premiered airing weekly on Nippon TV and the nationwide Nippon News Network from October 2, 2011. The series started to be collected in both DVD and Blu-ray format on January 25, 2012. Viz Media has licensed the anime for a DVD/Blu-ray release in North America with an English dub. On television, the series began airing on Adult Swim\'s Toonami programming block on April 17, 2016, and ended on June 23, 2019.The anime series\' opening theme is alternated between the song "Departure!" and an alternate version titled "Departure! -Second Version-" both sung by Galneryus\' vocalist Masatoshi Ono. Five pieces of music were used as the ending theme; "Just Awake" by the Japanese band Fear, and Loathing in Las Vegas in episodes 1 to 26, "Hunting for Your Dream" by Galneryus in episodes 27 to 58, "Reason" sung by Japanese duo Yuzu in episodes 59 to 75, "Nagareboshi Kirari" also sung by Yuzu from episode 76 to 98, which was originally from the anime film adaptation, Hunter × Hunter: Phantom Rouge, and "Hyōri Ittai" by Yuzu featuring Hyadain from episode 99 to 146, which was also used in the film Hunter × Hunter: The Last Mission. The background music and soundtrack for the series was composed by Yoshihisa Hirano. Page: List of Hunter × Hunter characters\nSummary: The Hunter × Hunter manga series, created by Yoshihiro Togashi, features an extensive cast of characters. It takes place in a fictional universe where licensed specialists known as Hunters travel the world taking on special jobs ranging from treasure hunting to assassination. The story initially focuses on Gon Freecss and his quest to become a Hunter in order to find his father, Ging, who is himself a famous Hunter. On the way, Gon meets and becomes close friends with Killua Zoldyck, Kurapika and Leorio Paradinight.\nAlthough most characters are human, most possess superhuman strength and/or supernatural abilities due to Nen, the ability to control one\'s own life energy or aura. The world of the series also includes fantastical beasts such as the Chimera Ants or the Five great calamities.' ``` diff --git a/pages/modules/agents/tools/examples/wolfram_alpha.md b/pages/modules/agents/tools/examples/wolfram_alpha.mdx similarity index 58% rename from pages/modules/agents/tools/examples/wolfram_alpha.md rename to pages/modules/agents/tools/examples/wolfram_alpha.mdx index f049e0c..1fca9dc 100644 --- a/pages/modules/agents/tools/examples/wolfram_alpha.md +++ b/pages/modules/agents/tools/examples/wolfram_alpha.mdx @@ -1,4 +1,27 @@ +import Head from 'next/head' + + + + + +![LangChain](https://pica.zhimg.com/50/v2-56e8bbb52aa271012541c1fe1ceb11a2_r.gif) + + + + Wolfram Alpha ==================== @@ -15,33 +38,33 @@ Wolfram Alpha 1. 将您的APP ID保存到WOLFRAM_ALPHA_APPID环境变量中 -``` +``` python pip install wolframalpha ``` -``` +``` python import os os.environ["WOLFRAM_ALPHA_APPID"] = "" ``` -``` +``` python from langchain.utilities.wolfram_alpha import WolframAlphaAPIWrapper ``` -``` +``` python wolfram = WolframAlphaAPIWrapper() ``` -``` +``` python wolfram.run("What is 2x+5 = -3x + 7?") ``` -``` +``` python 'x = 2/5' ``` diff --git a/pages/modules/agents/tools/examples/zapier.md b/pages/modules/agents/tools/examples/zapier.mdx similarity index 94% rename from pages/modules/agents/tools/examples/zapier.md rename to pages/modules/agents/tools/examples/zapier.mdx index d564624..bc0b2f5 100644 --- a/pages/modules/agents/tools/examples/zapier.md +++ b/pages/modules/agents/tools/examples/zapier.mdx @@ -1,4 +1,27 @@ +import Head from 'next/head' + + + + + +![LangChain](https://pica.zhimg.com/50/v2-56e8bbb52aa271012541c1fe1ceb11a2_r.gif) + + + + Zapier ================ @@ -21,13 +44,13 @@ NLA为签署NLA API请求提供API密钥和OAuth。 此示例介绍如何使用Zapier集成`SimpleSequentialChain`，然后使用`Agent`。 下面是代码： -``` +``` python %load_ext autoreload %autoreload 2 ``` -``` +``` python import os # get from https://platform.openai.com/ @@ -43,7 +66,7 @@ os.environ["ZAPIER_NLA_API_KEY"] = os.environ.get("ZAPIER_NLA_API_KEY", "") Zapier工具可与代理一起使用。请参见下面的示例。 -``` +``` python from langchain.llms import OpenAI from langchain.agents import initialize_agent from langchain.agents.agent_toolkits import ZapierToolkit @@ -52,7 +75,7 @@ from langchain.utilities.zapier import ZapierNLAWrapper ``` -``` +``` python ## step 0. expose gmail 'find email' and slack 'send channel message' actions # first go here, log in, expose (enable) the two actions: https://nla.zapier.com/demo/start -- for this example, can leave all fields "Have AI guess" @@ -60,7 +83,7 @@ from langchain.utilities.zapier import ZapierNLAWrapper ``` -``` +``` python llm = OpenAI(temperature=0) zapier = ZapierNLAWrapper() toolkit = ZapierToolkit.from_zapier_nla_wrapper(zapier) @@ -68,12 +91,12 @@ agent = initialize_agent(toolkit.get_tools(), llm, agent=AgentType.ZERO_SHOT_REA ``` -``` +``` python agent.run("Summarize the last email I received regarding Silicon Valley Bank.

And I did that 4 days ago, when I nominated Circuit Court of Appeals Judge Ketanji Brown Jackson. One of our nation’s top legal minds, who will continue Justice Breyer’s legacy of excellence.', metadata={'source': '../../state_of_the_union.txt'}) ``` @@ -176,12 +199,12 @@ Document(page_content='Tonight.

There have been a variety of document data collections to facilitate the development of DL models. Some examples include PRImA [3](magazine layouts), PubLayNet [38](academic paper layouts), Table Bank [18](tables in academic papers), Newspaper Navigator Dataset [16, 17](newspaper figure layouts) and HJDataset [31](historical Japanese document layouts). A spectrum of models trained on these datasets are currently available in the LayoutParser model zoo to support different use cases.

In July 2020, OpenAI unveiled GPT-3, a language model that was easily the largest known at the time. Put simply, GPT-3 is trained to predict the next word in a sentence, much like how a text message autocomplete feature works. A large language model, or LLM, is a deep learning algorithm that can recognize, summarize, translate, predict and generate text and other content based on knowledge gained from massive datasets. Large language models are among the most successful applications of transformer models.

Its chapters have been collected in 37 tankōbon volumes as of November 2022. The story focuses on a young boy named Gon Freecss who discovers that his father, who left him at a young age, is actually a world-renowned Hunter, a licensed professional who specializes in fantastical pursuits such as locating rare or unidentified animal species, treasure hunting, surveying unexplored enclaves, or hunting down lawless individuals. Gon departs on a journey to become a Hunter and eventually find his father. Along the way, Gon meets various other Hunters and encounters the paranormal.\nHunter × Hunter was adapted into a 62-episode anime television series produced by Nippon Animation and directed by Kazuhiro Furuhashi, which ran on Fuji Television from October 1999 to March 2001. Three separate original video animations (OVAs) totaling 30 episodes were subsequently produced by Nippon Animation and released in Japan from 2002 to 2004. A second anime television series by Madhouse aired on Nippon Television from October 2011 to September 2014, totaling 148 episodes, with two animated theatrical films released in 2013. There are also numerous audio albums, video games, musicals, and other media based on Hunter × Hunter.\nThe manga has been translated into English and released in North America by Viz Media since April 2005. Both television series have been also licensed by Viz Media, with the first series having aired on the Funimation Channel in 2009 and the second series broadcast on Adult Swim\'s Toonami programming block from April 2016 to June 2019.\nHunter × Hunter has been a huge critical and financial success and has become one of the best-selling manga series of all time, having over 84 million copies in circulation by July 2022. Page: Hunter × Hunter (2011 TV series)\nSummary: Hunter × Hunter is an anime television series that aired from 2011 to 2014 based on Yoshihiro Togashi\'s manga series Hunter × Hunter. The story begins with a young boy named Gon Freecss, who one day discovers that the father who he thought was dead, is in fact alive and well. He learns that his father, Ging, is a legendary "Hunter", an individual who has proven themselves an elite member of humanity. Despite the fact that Ging left his son with his relatives in order to pursue his own dreams, Gon becomes determined to follow in his father\'s footsteps, pass the rigorous "Hunter Examination", and eventually find his father to become a Hunter in his own right.\nThis new Hunter × Hunter anime was announced on July 24, 2011. It is a complete reboot of the anime adaptation starting from the beginning of the manga, with no connections to the first anime from 1999. Produced by Nippon TV, VAP, Shueisha and Madhouse, the series is directed by Hiroshi Kōjina, with Atsushi Maekawa and Tsutomu Kamishiro handling series composition, Takahiro Yoshimatsu designing the characters and Yoshihisa Hirano composing the music. Instead of having the old cast reprise their roles for the new adaptation, the series features an entirely new cast to voice the characters. The new series premiered airing weekly on Nippon TV and the nationwide Nippon News Network from October 2, 2011. The series started to be collected in both DVD and Blu-ray format on January 25, 2012. Viz Media has licensed the anime for a DVD/Blu-ray release in North America with an English dub. On television, the series began airing on Adult Swim\'s Toonami programming block on April 17, 2016, and ended on June 23, 2019.The anime series\' opening theme is alternated between the song "Departure!" and an alternate version titled "Departure! -Second Version-" both sung by Galneryus\' vocalist Masatoshi Ono. Five pieces of music were used as the ending theme; "Just Awake" by the Japanese band Fear, and Loathing in Las Vegas in episodes 1 to 26, "Hunting for Your Dream" by Galneryus in episodes 27 to 58, "Reason" sung by Japanese duo Yuzu in episodes 59 to 75, "Nagareboshi Kirari" also sung by Yuzu from episode 76 to 98, which was originally from the anime film adaptation, Hunter × Hunter: Phantom Rouge, and "Hyōri Ittai" by Yuzu featuring Hyadain from episode 99 to 146, which was also used in the film Hunter × Hunter: The Last Mission. The background music and soundtrack for the series was composed by Yoshihisa Hirano. Page: List of Hunter × Hunter characters\nSummary: The Hunter × Hunter manga series, created by Yoshihiro Togashi, features an extensive cast of characters. It takes place in a fictional universe where licensed specialists known as Hunters travel the world taking on special jobs ranging from treasure hunting to assassination. The story initially focuses on Gon Freecss and his quest to become a Hunter in order to find his father, Ging, who is himself a famous Hunter. On the way, Gon meets and becomes close friends with Killua Zoldyck, Kurapika and Leorio Paradinight.\nAlthough most characters are human, most possess superhuman strength and/or supernatural abilities due to Nen, the ability to control one\'s own life energy or aura.

Deno offers built-in support for environment variables with `Deno.env`, and you can also use a `.env` file to store and access environment variables. Using `Deno.env` is simple. It has getter and setter methods, so you can easily set and retrieve environment variables. For example, you can set the `FIREBASE_API_KEY` and `FIREBASE_AUTH_DOMAIN` environment variables like this: ```ts\nDeno.env.set("FIREBASE_API_KEY", "examplekey123");\nDeno.env.set("FIREBASE_AUTH_DOMAIN", "firebasedomain.com"); console.log(Deno.env.get("FIREBASE_API_KEY")); // examplekey123\nconsole.log(Deno.env.get("FIREBASE_AUTH_DOMAIN")); // firebasedomain.com\n``` You can also store environment variables in a `.env` file. This is a great'}, {'text': ' Environment variables are a powerful tool for managing configuration settings in a program. They allow us to set values that can be used by the program, without having to hard-code them into the code. This makes it easier to change settings without having to modify the code. In Deno, environment variables can be set in a few different ways. The most common way is to use the `VAR=value` syntax. This will set the environment variable `VAR` to the value `value`. This can be used to set any number of environment variables before running a command. For example, if we wanted to set the environment variable `VAR` to `hello` before running a Deno command, we could do so like this: ```\nVAR=hello deno run main.ts\n``` This will set the environment variable `VAR` to `hello` before running the command. We can then access this variable in our code using the `Deno.env.get()` function. For example, if we ran the following command: ```\nVAR=hello && deno eval "console.log(\'Deno: \' + Deno.env.get(\'VAR'}, {'text': ' Environment variables are a powerful tool for developers, allowing them to store and access data without having to hard-code it into their applications. In Deno, you can access environment variables using the `Deno.env.get()` function. For example, if you wanted to access the `HOME` environment variable, you could do so like this: ```js\n// env.js\nDeno.env.get("HOME");\n``` When running this code, you\'ll need to grant the Deno process access to environment variables. This can be done by passing the `--allow-env` flag to the `deno run` command. You can also specify which environment variables you want to grant access to, like this: ```shell\n# Allow access to only the HOME env var\ndeno run --allow-env=HOME env.js\n``` It\'s important to note that environment variables are case insensitive on Windows, so Deno also matches them case insensitively (on Windows only). Another thing to be aware of when using environment variables is subprocess permissions. Subprocesses are powerful and can access system resources regardless of the permissions you granted to the Den'}, {'text': ' Environment variables are an important part of any programming language, and Deno is no exception. Deno is a secure JavaScript and TypeScript runtime built on the V8 JavaScript engine, and it recently added support for environment variables. This feature was added in Deno version 1.6.0, and it is now available for use in Deno applications. Environment variables are used to store information that can be used by programs. They are typically used to store configuration information, such as the location of a database or the name of a user. In Deno, environment variables are stored in the `Deno.env` object. This object is similar to the `process.env` object in Node.js, and it allows you to access and set environment variables. The `Deno.env` object is a read-only object, meaning that you cannot directly modify the environment variables. Instead, you must use the `Deno.env.set()` function to set environment variables. This function takes two arguments: the name of the environment variable and the value to set it to. For example, if you wanted to set the `FOO` environment variable to `bar`, you would use the following code: ```'}] ``` diff --git a/pages/modules/indexes/document_loaders/examples/airbyte_json.mdx b/pages/modules/indexes/document_loaders/examples/airbyte_json.mdx index 077e2a5..bbc0bfe 100644 --- a/pages/modules/indexes/document_loaders/examples/airbyte_json.mdx +++ b/pages/modules/indexes/document_loaders/examples/airbyte_json.mdx @@ -56,37 +56,37 @@ Airbyte JSON[#](#airbyte-json "跳转到标题") - 找到您的数据并复制路径。该路径应保存在下面的文件变量中。它应该以`/tmp/airbyte_local`开头 -``` +```python from langchain.document_loaders import AirbyteJSONLoader ``` -``` +```python !ls /tmp/airbyte_local/json_data/ ``` -``` +```python _airbyte_raw_pokemon.jsonl ``` -``` +```python loader = AirbyteJSONLoader('/tmp/airbyte_local/json_data/_airbyte_raw_pokemon.jsonl') ``` -``` +```python data = loader.load() ``` -``` +```python print(data[0].page_content[:500]) ``` -``` +```python abilities: ability: name: blaze diff --git a/pages/modules/indexes/document_loaders/examples/apify_dataset.mdx b/pages/modules/indexes/document_loaders/examples/apify_dataset.mdx index 62c0fb9..e28a51f 100644 --- a/pages/modules/indexes/document_loaders/examples/apify_dataset.mdx +++ b/pages/modules/indexes/document_loaders/examples/apify_dataset.mdx @@ -39,14 +39,14 @@ Apify数据集[#](#apify-dataset "此标题的永久链接") 您需要在Apify平台上拥有现有的数据集。如果您没有，请先查看[此教程](../../../agents/tools/examples/apify)，了解如何使用Apify从文档、知识库、帮助中心或博客中提取内容。 -``` +```python #!pip install apify-client ``` 首先，将`ApifyDatasetLoader`导入您的源代码中: -``` +```python from langchain.document_loaders import ApifyDatasetLoader from langchain.document_loaders.base import Document @@ -56,7 +56,7 @@ from langchain.document_loaders.base import Document 例如，如果你的数据集项结构如下： -``` +```python { "url": "https://apify.com", "text": "Apify is the best web scraping and automation platform." @@ -66,7 +66,7 @@ from langchain.document_loaders.base import Document 下面代码中的映射函数将把它们转换为LangChain `Document`格式，以便您可以将其进一步与任何LLM模型一起使用（例如用于问答)。 -``` +```python loader = ApifyDatasetLoader( dataset_id="your-dataset-id", dataset_mapping_function=lambda dataset_item: Document( @@ -76,7 +76,7 @@ loader = ApifyDatasetLoader( ``` -``` +```python data = loader.load() ``` @@ -86,14 +86,14 @@ data = loader.load() 在此示例中，我们使用数据集中的数据回答一个问题。 -``` +```python from langchain.docstore.document import Document from langchain.document_loaders import ApifyDatasetLoader from langchain.indexes import VectorstoreIndexCreator ``` -``` +```python loader = ApifyDatasetLoader( dataset_id="your-dataset-id", dataset_mapping_function=lambda item: Document( @@ -103,24 +103,24 @@ loader = ApifyDatasetLoader( ``` -``` +```python index = VectorstoreIndexCreator().from_loaders([loader]) ``` -``` +```python query = "What is Apify?" result = index.query_with_sources(query) ``` -``` +```python print(result["answer"]) print(result["sources"]) ``` -``` +```python Apify is a platform for developing, running, and sharing serverless cloud programs.

We believe that the most powerful and differentiated applications will not only call out to a language model via an API, but will also:\nBe data-aware: connect a language model to other sources of data\nBe agentic: allow a language model to interact with its environment\nThe LangChain framework is designed with the above principles in mind.\nThis is the Python specific portion of the documentation. For a purely conceptual guide to LangChain, see here. For the JavaScript documentation, see here.\nGetting Started\nCheckout the below guide for a walkthrough of how to get started using LangChain to create an Language Model application.\nGetting Started Documentation\nModules\nThere are several main modules that LangChain provides support for. For each module we provide some examples to get started, how-to guides, reference docs, and conceptual guides. These modules are, in increasing order of complexity:\nModels: The various model types and model integrations LangChain supports.\nPrompts: This includes prompt management, prompt optimization, and prompt serialization.\nMemory: Memory is the concept of persisting state between calls of a chain/agent. LangChain provides a standard interface for memory, a collection of memory implementations, and examples of chains/agents that use memory.\nIndexes: Language models are often more powerful when combined with your own text data - this module covers best practices for doing exactly that.\nChains: Chains go beyond just a single LLM call, and are sequences of calls (whether to an LLM or a different utility). LangChain provides a standard interface for chains, lots of integrations with other tools, and end-to-end chains for common applications.\nAgents: Agents involve an LLM making decisions about which Actions to take, taking that Action, seeing an Observation, and repeating that until done. LangChain provides a standard interface for agents, a selection of agents to choose from, and examples of end to end agents.\nUse Cases\nThe above modules can be used in a variety of ways. LangChain also provides guidance and assistance in this. Below are some of the common use cases LangChain supports.\nPersonal Assistants: The main LangChain use case. Personal assistants need to take actions, remember interactions, and have knowledge about your data.\nQuestion Answering: The second big LangChain use case. Answering questions over specific documents, only utilizing the information in those documents to construct an answer.\nChatbots: Since language models are good at producing text, that makes them ideal for creating chatbots.\nQuerying Tabular Data: If you want to understand how to use LLMs to query data that is stored in a tabular format (csvs, SQL, dataframes, etc) you should read this page.\nInteracting with APIs: Enabling LLMs to interact with APIs is extremely powerful in order to give them more up-to-date information and allow them to take actions.\nExtraction: Extract structured information from text.\nSummarization: Summarizing longer documents into shorter, more condensed chunks of information. A type of Data Augmented Generation.\nEvaluation: Generative models are notoriously hard to evaluate with traditional metrics. One new way of evaluating them is using language models themselves to do the evaluation. LangChain provides some prompts/chains for assisting in this.\nReference Docs\nAll of LangChain’s reference documentation, in one place. Full documentation on all methods, classes, installation methods, and integration setups for LangChain.\nReference Documentation\nLangChain Ecosystem\nGuides for how other companies/products can be used with LangChain\nLangChain Ecosystem\nAdditional Resources\nAdditional collection of resources we think may be useful as you develop your application!\nLangChainHub: The LangChainHub is a place to share and explore other prompts, chains, and agents.\nGlossary: A glossary of all related terms, papers, methods, etc. Whether implemented in LangChain or not!\nGallery: A collection of our favorite projects that use LangChain. Useful for finding inspiration or seeing how things were done in other applications.\nDeployments: A collection of instructions, code snippets, and template repositories for deploying LangChain apps.\nTracing: A guide on using tracing in LangChain to visualize the execution of chains and agents.\nModel Laboratory: Experimenting with different prompts, models, and chains is a big part of developing the best possible application. The ModelLaboratory makes it easy to do so.\nDiscord: Join us on our Discord to discuss all things LangChain!\nProduction Support: As you move your LangChains into production, we’d love to offer more comprehensive support.

I also heard that at first it was seized by U.S. customs if it ever tried to enter this country, therefore being a fan of films considered "controversial" I really had to see this for myself.

The plot is centered around a young Swedish drama student named Lena who wants to learn everything she can about life. In particular she wants to focus her attentions to making some sort of documentary on what the average Swede thought about certain political issues such as the Vietnam War and race issues in the United States. In between asking politicians and ordinary denizens of Stockholm about their opinions on politics, she has sex with her drama teacher, classmates, and married men.

What kills me about I AM CURIOUS-YELLOW is that 40 years ago, this was considered pornographic. Really, the sex and nudity scenes are few and far between, even then it\'s not shot like some cheaply made porno. While my countrymen mind find it shocking, in reality sex and nudity are a major staple in Swedish cinema. Even Ingmar Bergman, arguably their answer to good old boy John Ford, had sex scenes in his films.

I do commend the filmmakers for the fact that any sex shown in the film is shown for artistic purposes rather than just to shock people and make money to be shown in pornographic theaters in America. I AM CURIOUS-YELLOW is a good film for anyone wanting to study the meat and potatoes (no pun intended) of Swedish cinema. But really, this film doesn\'t have much of a plot.', metadata={'label': 0}), Document(page_content='"I Am Curious: Yellow" is a risible and pretentious steaming pile. It doesn\'t matter what one\'s political views are because this film can hardly be taken seriously on any level. As for the claim that frontal male nudity is an automatic NC-17, that isn\'t true. I\'ve seen R-rated films with male nudity. Granted, they only offer some fleeting views, but where are the R-rated films with gaping vulvas and flapping labia? Nowhere, because they don\'t exist. The same goes for those crappy cable shows: schlongs swinging in the breeze but not a clitoris in sight. And those pretentious indie movies like The Brown Bunny, in which we\'re treated to the site of Vincent Gallo\'s throbbing johnson, but not a trace of pink visible on Chloe Sevigny. Before crying (or implying) "double-standard" in matters of nudity, the mentally obtuse should take into account one unavoidably obvious anatomical difference between men and women: there are no genitals on display when actresses appears nude, and the same cannot be said for a man. In fact, you generally won\'t see female genitals in an American film in anything short of porn or explicit erotica. This alleged double-standard is less a double standard than an admittedly depressing ability to come to terms culturally with the insides of women\'s bodies.', metadata={'label': 0}), Document(page_content="If only to avoid making this type of film in the future.

How do i fix this. I just bought it last week.\nI restored as manufactures cleaned up the screen\nthe problem continues\n\n## 27 Answers\n\nFilter by: \n\nMost Helpful\nNewest\nOldest\n\n### Accepted Answer\nHi,\nWhere did you buy it? If you bought it from Apple or from an official retailer like Carphone warehouse etc. Then you\'ll have a year warranty and can get it replaced free.\nIf you bought it second hand, from a third part repair shop or online, then it may still have warranty, unless it is refurbished and has been repaired elsewhere.\nIf this is the case, it may be the screen that needs replacing to solve your issue.\nEither way, wherever you got it, it\'s best to return it and get a refund or a replacement device. :-)\n\n\n\n### Most Helpful Answer\nI had the same issues, screen freezing, opening apps by itself, selecting the screens and typing on it\'s own. I first suspected aliens and then ghosts and then hackers.\niPhone 6 is weak physically and tend to bend on pressure. And my phone had no case or cover.\nI took the phone to apple stores and they said sensors need to be replaced and possibly screen replacement as well. My phone is just 17 months old.\nHere is what I did two days ago and since then it is working like a charm..\nHold the phone in portrait (as if watching a movie). Twist it very very gently. do it few times.Rest the phone for 10 mins (put it on a flat surface). You can now notice those self typing things gone and screen getting stabilized.\nThen, reset the hardware (hold the power and home button till the screen goes off and comes back with apple logo). release the buttons when you see this.\nThen, connect to your laptop and log in to iTunes and reset your phone completely. (please take a back-up first).\nAnd your phone should be good to use again.\nWhat really happened here for me is that the sensors might have stuck to the screen and with mild twisting, they got disengaged/released.\nI posted this in Apple Community and the moderators deleted it, for the best reasons known to them.\nInstead of throwing away your phone (or selling cheaply), try this and you could be saving your phone.\nLet me know how it goes.\n\n\n\n### Other Answer\nIt was the charging cord! I bought a gas station braided cord and it was the culprit. Once I plugged my OEM cord into the phone the GHOSTS went away.\n\n\n\n### Other Answer\nI\'ve same issue that I just get resolved. I first tried to restore it from iCloud back, however it was not a software issue or any virus issue, so after restore same problem continues. Then I get my phone to local area iphone repairing lab, and they detected that it is an LCD issue. LCD get out of order without any reason (It was neither hit or nor slipped, but LCD get out of order all and sudden, while using it) it started opening things at random. I get LCD replaced with new one, that cost me $80.00 in total ($70.00 LCD charges + $10.00 as labor charges to fix it). iPhone is back to perfect mode now. It was iphone 6s. Thanks.\n\n\n\n### Other Answer\nI was having the same issue with my 6 plus, I took it to a repair shop, they opened the phone, disconnected the three ribbons the screen has, blew up and cleaned the connectors and connected the screen again and it solved the issue… it’s hardware, not software.\n\n\n\n### Other Answer\nHey.\nJust had this problem now. As it turns out, you just need to plug in your phone. I use a case and when I took it off I noticed that there was a lot of dust and dirt around the areas that the case didn\'t cover. I shined a light in my ports and noticed they were filled with dust. Tomorrow I plan on using pressurized air to clean it out and the problem should be solved. If you plug in your phone and unplug it and it stops the issue, I recommend cleaning your phone thoroughly.\n\n\n\n### Other Answer\nI simply changed the power supply and problem was gone. The block that plugs in the wall not the sub cord. The cord was fine but not the block.\n\n\n\n### Other Answer\nSomeone ask! I purchased my iPhone 6s Plus for 1000 from at&t. Before I touched it, I purchased a otter defender case. I read where at&t said touch desease was due to dropping! Bullshit!! I am 56 I have never dropped it!! Looks brand new! Never dropped or abused any way! I have my original charger. I am going to clean it and try everyone’s advice. It really sucks! I had 40,000,000 on my heart of Vegas slots! I play every day. I would be spinning and my fingers were no where max buttons and it would light up and switch to max. It did it 3 times before I caught it light up by its self. It sucks. Hope I can fix it!!!!\n\n\n\n### Other Answer\nNo answer, but same problem with iPhone 6 plus--random, self-generated jumping amongst apps and typing on its own--plus freezing regularly (aha--maybe that\'s what the "plus" in "6 plus" refers to?). An Apple Genius recommended upgrading to iOS 11.3.1 from 11.2.2, to see if that fixed the trouble. If it didn\'t, Apple will sell me a new phone for $168! Of couese the OS upgrade didn\'t fix the problem. Thanks for helping me figure out that it\'s most likely a hardware problem--which the "genius" probably knows too.\nI\'m getting ready to go Android.\n\n\n\n### Other Answer\nI experienced similar ghost touches. Two weeks ago, I changed my iPhone 6 Plus shell (I had forced the phone into it because it’s pretty tight), and also put a new glass screen protector (the edges of the protector don’t stick to the screen, weird, so I brushed pressure on the edges at times to see if they may smooth out one day miraculously). I’m not sure if I accidentally bend the phone when I installed the shell, or, if I got a defective glass protector that messes up the touch sensor. Well, yesterday was the worse day, keeps dropping calls and ghost pressing keys for me when I was on a call. I got fed up, so I removed the screen protector, and so far problems have not reoccurred yet. I’m crossing my fingers that problems indeed solved.\n\n\n\n### Other Answer\nthank you so much for this post! i was struggling doing the reset because i cannot type userids and passwords correctly because the iphone 6 plus i have kept on typing letters incorrectly. I have been doing it for a day until i come across this article. Very helpful! God bless you!!\n\n\n\n### Other Answer\nI just turned it off, and turned it back on.\n\n\n\n### Other Answer\nMy problem has not gone away completely but its better now i changed my charger and turned off prediction ....,,,now it rarely happens\n\n\n\n### Other Answer\nI tried all of the above. I then turned off my home cleaned it with isopropyl alcohol 90%. Then I baked it in my oven on warm for an hour and a half over foil. Took it out and set it cool completely on the glass top stove. Then I turned on and it worked.\n\n\n\n### Other Answer\nI think at& t should man up and fix your phone for free! You pay a lot for a Apple they should back it. I did the next 30 month payments and finally have it paid off in June. My iPad sept. Looking forward to a almost 100 drop in my phone bill! Now this crap!!! Really\n\n\n\n### Other Answer\nIf your phone is JailBroken, suggest downloading a virus. While all my symptoms were similar, there was indeed a virus/malware on the phone which allowed for remote control of my iphone (even while in lock mode). My mistake for buying a third party iphone i suppose. Anyway i have since had the phone restored to factory and everything is working as expected for now. I will of course keep you posted if this changes. Thanks to all for the helpful posts, really helped me narrow a few things down.\n\n\n\n### Other Answer\nWhen my phone was doing this, it ended up being the screen protector that i got from 5 below. I took it off and it stopped. I ordered more protectors from amazon and replaced it\n\n\n\n### Other Answer\niPhone 6 Plus first generation….I had the same issues as all above, apps opening by themselves, self typing, ultra sensitive screen, items jumping around all over….it even called someone on FaceTime twice by itself when I was not in the room…..I thought the phone was toast and i’d have to buy a new one took me a while to figure out but it was the extra cheap block plug I bought at a dollar store for convenience of an extra charging station when I move around the house from den to living room…..cord was fine but bought a new Apple brand block plug…no more problems works just fine now. This issue was a recent event so had to narrow things down to what had changed recently to my phone so I could figure it out.\nI even had the same problem on a laptop with documents opening up by themselves…..a laptop that was plugged in to the same wall plug as my phone charger with the dollar store block plug….until I changed the block plug.\n\n\n\n### Other Answer\nHad the problem: Inherited a 6s Plus from my wife. She had no problem with it.\nLooks like it was merely the cheap phone case I purchased on Amazon. It was either pinching the edges or torquing the screen/body of the phone. Problem solved.\n\n\n\n### Other Answer\nI bought my phone on march 6 and it was a brand new, but It sucks me uo because it freezing, shaking and control by itself. I went to the store where I bought this and I told them to replacr it, but they told me I have to pay it because Its about lcd issue. Please help me what other ways to fix it. Or should I try to remove the screen or should I follow your step above.\n\n\n\n### Other Answer\nI tried everything and it seems to come back to needing the original iPhone cable…or at least another 1 that would have come with another iPhone…not the $5 Store fast charging cables. My original cable is pretty beat up - like most that I see - but I’ve been beaten up much MUCH less by sticking with its use! I didn’t find that the casing/shell around it or not made any diff.\n\n\n\n### Other Answer\ngreat now I have to wait one more hour to reset my phone and while I was tryin to connect my phone to my computer the computer also restarted smh does anyone else knows how I can get my phone to work… my problem is I have a black dot on the bottom left of my screen an it wont allow me to touch a certain part of my screen unless I rotate my phone and I know the password but the first number is a 2 and it won\'t let me touch 1,2, or 3 so now I have to find a way to get rid of my password and all of a sudden my phone wants to touch stuff on its own which got my phone disabled many times to the point where I have to wait a whole hour and I really need to finish something on my phone today PLEASE HELPPPP\n\n\n\n### Other Answer\nIn my case , iphone 6 screen was faulty. I got it replaced at local repair shop, so far phone is working fine.\n\n\n\n### Other Answer\nthis problem in iphone 6 has many different scenarios and solutions, first try to reconnect the lcd screen to the motherboard again, if didnt solve, try to replace the lcd connector on the motherboard, if not solved, then remains two issues, lcd screen it self or touch IC. in my country some repair shops just change them all for almost 40$ since they dont want to troubleshoot one by one. readers of this comment also should know that partial screen not responding in other iphone models might also have an issue in LCD connector on the motherboard, specially if you lock/unlock screen and screen works again for sometime. lcd connectors gets disconnected lightly from the motherboard due to multiple falls and hits after sometime. best of luck for all\n\n\n\n### Other Answer\nI am facing the same issue whereby these ghost touches type and open apps , I am using an original Iphone cable , how to I fix this issue.\n\n\n\n### Other Answer\nThere were two issues with the phone I had troubles with. It was my dads and turns out he carried it in his pocket. The phone itself had a little bend in it as a result. A little pressure in the opposite direction helped the issue. But it also had a tiny crack in the screen which wasnt obvious, once we added a screen protector this fixed the issues entirely.\n\n\n\n### Other Answer\nI had the same problem with my 64Gb iPhone 6+.

I\r\n Thank you...\r\n \r\n CLOSE - KWAME TURE\r\n \r\n towering at Six Feet-Four with an infectious smile and\r\n Flawless Dark Skin, he\'s oozing Charisma out of every pore.\r\n He stands behind a small podium.\r\n \r\n KWAME TURE (CONT\'D)\r\n ...I\'m here to tell you this evening\r\n it is time for you to stop running\r\n away from being Black. You are\r\n College Students, you should think.\r\n KWAME TURE (CONT\'D)\r\n It is time for you to understand that\r\n you as The growing Intellectuals of\r\n this Country, you must define Beauty\r\n for Black People, Now that\'s Black\r\n Power.\r\n \r\n BLACK MASS\r\n BLACK POWER!!! BLACK POWER!!!\r\n \r\n The Black Students in The Audience are laser focused on him.\r\n \r\n KWAME TURE\r\n Is Beauty defined by someone with a\r\n Narrow Nose? Thin Lips? White Skin?\r\n You ain\'t got none of that. If your\r\n Lips are Thick, Bite them in. Hold\r\n your Nose! Don\'t drink Coffee because\r\n it makes you Black!\r\n \r\n The Audience laughs! Loving it.\r\n \r\n KWAME TURE (CONT\'D)\r\n Your Nose is Boss, your Lips are\r\n Thick, your skin is Black, you are\r\n Black and you are Beautiful!\r\n \r\n Everyone cheers including Ron!\r\n \r\n KWAME TURE (CONT\'D)\r\n We want to be like The White people\r\n that oppress us in this Country and\r\n since they hate us, we hate\r\n ourselves. You dig Tarzan? I remember\r\n that when I was a Boy I used to go\r\n see Tarzan Movies on Saturdays. I\r\n loved me some Jane too. Jane was A\r\n Fine White Woman. White Tarzan used\r\n to Beat up The Black Natives. I would\r\n sit there yelling "Kill The Beasts,\r\n Kill The Savages, Kill \'Em!" Actually\r\n I was saying: "Kill Me." It was as if\r\n a Jewish Boy watched Nazis taking\r\n Jews off to Concentration Camps and\r\n cheered them on. Today, I want The\r\n Chief to beat The Hell out of Tarzan\r\n and send him back to The Caves of\r\n Europe. But it takes time to become\r\n Free of The Lies and their shaming\r\n effect on Black Minds. It takes time\r\n to reject the most Important Lie:\r\n that Black People inherently can\'t do\r\n the same things White People can do\r\n unless White People help them.\r\n The Audience laughing, overwhelmed, shouting back support! A\r\n ROAR from The Crowd. Ron finds himself clapping along.\r\n \r\n RON STALLWORTH\r\n Right on!!! Right On!!!\r\n \r\n Ron looks around at everyone caught up in Kwame\'s spell.\r\n \r\n KWAME TURE (CONT\'D)\r\n If a White Man wants to Lynch Me,\r\n that\'s his Problem. If he\'s got The\r\n Power to Lynch Me, that\'s My Problem.\r\n Racism is not a question of Attitude;\r\n it\'s a question of Power.\r\n \r\n Ron is struck by the remark.\r\n \r\n KWAME TURE (CONT\'D)\r\n The vast majority of Negroes in this\r\n Country live in Captive Communities\r\n and must endure their conditions of\r\n Oppression because and only because\r\n they are Black and Powerless. Now We\r\n are being shot down like Dogs in the\r\n streets by White Racist Police. We\r\n can no longer accept this Oppression\r\n without retribution. The War in\r\n Vietnam is Illegal and Immoral. I\'d\r\n rather see a Brother Kill a Cop than\r\n Kill a Vietnamese. At least he\'s got\r\n a reason for Killing The Cop. When\r\n you Kill a Vietnamese you\'re a Hero\r\n and you don\'t even know why you\r\n Killed him. At least if you Kill a\r\n Cop you\'re doing it for a reason.\r\n \r\n Another Applause Break.\r\n \r\n CLOSE - RON\r\n \r\n Ron listens, challenged, torn.\r\n \r\n INT.

"If I am not\r\n for myself, who will be? If I am for\r\n myself alone, who am I? If not now,\r\n when? And if not you, who?" We need\r\n an Undying Love for Black People\r\n wherever We may be.

Her name was\r\n Pinky. She was probably the closest\r\n Woman to me other than Mother.\r\n \r\n RON STALLWORTH\r\n That surprises me.\r\n \r\n DEVIN DAVIS\r\n I know.

Ron, I\'m\r\n assigning you to be Security Detail\r\n for Davis.\r\n \r\n A Shockwave.\r\n \r\n RON STALLWORTH\r\n I don\'t think that\'s a wise\r\n decision...\r\n LANDERS\r\n ...Davis needs protection.

A pissed Master\r\n Patrolman Landers turns to Chief Bridges for support but he\r\n says nothing. Landers then Exits. Chief says to Ron.\r\n CHIEF BRIDGES\r\n If you let him get to you that easy,\r\n you ain\'t got a Shot with Devin\r\n Davis.\r\n \r\n Ron takes his SMALL NOTE PAD out and writes something down\r\n again.

So\r\n Walker, nothing but rubble...\r\n \r\n WALKER\r\n ...And Barbecue Niggers.\r\n \r\n Ivanhoe laughs, liking that. Walker carefully removes another\r\n Smaller Bomb from the bag.

However\r\n I am a Professional and I will do\r\n everything within my means and beyond\r\n to keep you safe.\r\n \r\n Davis stands there a moment, processing all of this.

Ron sees something.\r\n \r\n RON STALLWORTH\r\n Jeezus Christ.\r\n \r\n PATRICE\r\n What?\r\n \r\n RON STALLWORTH\r\n Your Boyfriend.\r\n \r\n Patrice turns and sees.\r\n \r\n PATRICE\r\n Oh My God.\r\n \r\n Master Patrolman Landers nears them with a Beer in his hand.\r\n \r\n LANDERS\r\n Who\'s da\' Soul Sistah, Stallworth?\r\n You been holding out on me.\r\n \r\n Patrice stares at him with contempt.\r\n \r\n PATRICE\r\n You don\'t remember me do you?\r\n \r\n Landers stares at her.\r\n PATRICE (CONT\'D)\r\n Kwame Ture.\r\n \r\n Landers doesn\'t know who that is.\r\n \r\n PATRICE (CONT\'D)\r\n Stokely Carmichael.\r\n \r\n LANDERS\r\n Oh Yeah, Yeah, you looked good that\r\n night but you look even better now.\r\n \r\n PATRICE\r\n How often do you do that to Black\r\n People?\r\n \r\n LANDERS\r\n Do what?\r\n \r\n PATRICE\r\n Pull us over for nothing. Harass us.\r\n Put your hands all over a Woman in\r\n the guise of searching her. Call us\r\n everything but A Child of God.\r\n \r\n LANDERS\r\n I don\'t know what you\'re talking\r\n about.\r\n \r\n RON STALLWORTH\r\n It\'s like what I told you. He just\r\n likes taking advantage but in the end\r\n he\'s All Hat and No Cattle.\r\n \r\n Landers looks around then leans in close to Patrice and Ron.\r\n He speaks softly issuing a deadly threat.\r\n \r\n LANDERS\r\n Let me tell you both something, I\'ve\r\n been keeping you People in line in\r\n this City for years. What I did to\r\n your Girl that night, I can do to any\r\n of you, Anytime, Anyplace. That\'s my\r\n prerogative. I can even Bust a Cap in\r\n ya Black Ass if I feel like it and\r\n nuthin\' will be done about it. Get\r\n it? Wish the both of you got blown up\r\n instead of Good White Folks.\r\n \r\n Master Patrolman Landers raises up.\r\n \r\n RON STALLWORTH\r\n Ohhh, I get it.\r\n \r\n Ron looks at Patrice.\r\n RON STALLWORTH (CONT\'D)\r\n You get it, Patrice?\r\n \r\n PATRICE\r\n Oh, I totally and completely get it.\r\n \r\n Landers looks confused with their response.\r\n \r\n RON STALLWORTH\r\n Good.\r\n \r\n Ron turns toward the Bar and shouts.\r\n \r\n RON STALLWORTH (CONT\'D)\r\n You get it, Flip?\r\n \r\n Behind the Bar, Flip leans out from the back room waving to\r\n Ron wearing Headphones recording The Conversation.\r\n \r\n FLIP\r\n Oh, We got it! We got it all!\r\n \r\n Ron stands removing his Shirt revealing The Wire he is\r\n wearing. Master Patrolman Landers is in shock.\r\n \r\n RON STALLWORTH\r\n You get it, Chief?\r\n \r\n Sgt. Trapp appears taking the Beer from Landers\' hand turning\r\n him around putting Handcuffs on him. Chief Bridges comes from\r\n the back nearing Landers. The two lock eyes.\r\n \r\n CHIEF BRIDGES\r\n Oh, I really, really get it. You\'re\r\n under arrest for Police Misconduct,\r\n Sexual Misconduct and Police\r\n Brutality.\r\n \r\n Sgt. Trapp and the Chief usher Master Patrolman Landers, who\r\n is babbling like a Fool out of The Bar reading him his\r\n rights.\r\n \r\n INT. INTELLIGENCE UNIT - CSPD - DAY\r\n \r\n Ron, walking taller than usual, steps inside The Unit. Some\r\n of his Colleagues notice and give him a Low-Key Ovation. At\r\n his Desk is Flip, who is in Great Spirits.\r\n \r\n FLIP\r\n There he is... Man of the Minute.\r\n \r\n RON STALLWORTH\r\n ... not an Hour?\r\n \r\n Ron smiles, gives Fives all around. They all share a laugh.\r\n FLIP (CONT\'D)\r\n That Polaroid Stunt you pulled? When\r\n you threw your Arms around them, I\r\n swear to God I almost Shit myself!\r\n \r\n RON STALLWORTH\r\n Told you, Ron was born ready.\r\n \r\n FLIP\r\n Born ready is Ron.\r\n \r\n Sgt. Trapp steps out of his Office.\r\n \r\n SGT. TRAPP\r\n There\'s The Crazy Son of a Bitch!!!\r\n \r\n Trapp gives Ron a Bear Hug.\r\n \r\n SGT. TRAPP (CONT\'D)\r\n You did good.\r\n \r\n RON STALLWORTH\r\n Sarge. We did good.\r\n \r\n Ron and Flip eyes meet, bonded.\r\n \r\n SGT. TRAPP\r\n Chief wants to see you Guys.\r\n \r\n Flip nudges Ron.\r\n \r\n FLIP\r\n Hey... early promotion?\r\n \r\n Ron smiles.\r\n \r\n INT. OFFICE OF THE CHIEF OF POLICE - DAY\r\n \r\n Ron, Flip, and Sgt. Trapp sit opposite Chief Bridges.\r\n \r\n CHIEF BRIDGES\r\n Again, I can\'t commend you enough for\r\n what you\'ve achieved. You know there\r\n was not a Single Cross Burning the\r\n entire time you were involved?\r\n \r\n RON STALLWORTH\r\n I\'m aware.\r\n \r\n CHIEF BRIDGES\r\n But all good things must come to an\r\n end...\r\n \r\n Sgt. Trapp shakes his head, resigned.\r\n RON STALLWORTH\r\n What does that mean?\r\n \r\n Ron and Flip look at each other, stunned.\r\n \r\n CHIEF BRIDGES\r\n Budget Cuts.\r\n \r\n FLIP\r\n Budget Cuts?\r\n \r\n CHIEF BRIDGES\r\n Inflation... I wish I had a choice.\r\n My hands are tied. Besides, it looks\r\n like there are no longer any tangible\r\n Threats...\r\n \r\n RON STALLWORTH\r\n ...Sounds like we did too good a job.\r\n \r\n CHIEF BRIDGES\r\n Not a Bad Legacy to leave.\r\n \r\n Bridges takes a deliberate pause. Then, THE Sucker Punch...\r\n \r\n CHIEF BRIDGES (CONT\'D)\r\n And I need you, Ron Stallworth, to\r\n destroy all Evidence of this\r\n Investigation.\r\n \r\n RON STALLWORTH\r\n Excuse me?\r\n \r\n FLIP\r\n This is total Horseshit.\r\n \r\n CHIEF BRIDGES\r\n We prefer that The Public never knew\r\n about this Investigation.\r\n \r\n Ron and Flip are heated. Sgt. Trapp is silent but gutted.\r\n \r\n RON STALLWORTH\r\n If they found out...\r\n \r\n CHIEF BRIDGES\r\n ...Cease all further contact with The\r\n Ku Klux Klan. Effective immediately.\r\n That goes for Flip too. Ron\r\n Stallworth...\r\n \r\n RON STALLWORTH\r\n This is some Fucked up Bullshit.\r\n CHIEF BRIDGES\r\n Take a week off. Go on vacation with\r\n your Girlfriend. We\'ll hold down The\r\n Fort until you get back. Get you\r\n another assignment...Narcotics.\r\n \r\n Ron storms out.\r\n \r\n INT. INTELLIGENCE UNIT - CSPD - DAY\r\n \r\n Ron reflects as he feeds Investigation documents in a\r\n Shredder. The documents shred into pieces. Just then, the\r\n Undercover Phone Line rings on Ron\'s desk.\r\n \r\n Ron stares at the Phone, still ringing. He looks at The\r\n Documents in his hand, about to feed them into The Shredder.\r\n Ron stops. Throws The Documents in a Folder. Sweeps some\r\n Folders into his Briefcase. Leaves as The Phone still rings.\r\n \r\n EXT. COLORADO SPRINGS POLICE DEPARTMENT BUILDING - DAY\r\n \r\n Ron is walking fast now, trying to make it out of The\r\n Building with The Evidence but he remembers something.\r\n He stops, turns back.\r\n \r\n INT. INTELLIGENCE DIVISION - CSPD - DAY\r\n \r\n Ron sits at his Desk, on The Undercover Phone Line. Flip,\r\n Jimmy and Sgt. Trapp are behind, both close enough to listen,\r\n giggling.\r\n \r\n RON STALLWORTH\r\n I\'m sorry we didn\'t get to spend more\r\n One-on-One time together.\r\n \r\n INT. DEVIN DAVIS OFFICE - DAY\r\n \r\n INTERCUT RON, FLIP, AND TRAPP WITH DEVIN DAVIS:\r\n \r\n DEVIN DAVIS\r\n Well, that tragic event. I had just\r\n met those Fine Brothers in the cause.\r\n \r\n RON STALLWORTH\r\n Our Chapter is just shaken to the\r\n core. And poor Connie not only does\r\n she lose her Husband but she\'s facing\r\n a healthy Prison Sentence.\r\n \r\n DEVIN DAVIS\r\n My God. And then there was that one\r\n Nigger Detective who threatened me.\r\n RON STALLWORTH\r\n Goddamn Coloreds sure know how to\r\n spoil a Celebration.\r\n \r\n Flip and Jimmy snort. Ron holds in a Belly-Laugh.\r\n \r\n DEVIN DAVIS\r\n Christ. You can say that again.\r\n \r\n Ron cracks up into his Hand. Sgt. Trapp is wheezing-- his\r\n Face Bright Pink. Flip is laughing hard in the background.\r\n \r\n RON STALLWORTH\r\n Can I ask you something? That Nigger\r\n Detective who gave you a hard time?\r\n Ever get his name?\r\n \r\n DEVIN DAVIS\r\n No, I...\r\n \r\n RON STALLWORTH\r\n ...Are-uh you sure you don\'t know who\r\n he is? Are-uh you absolutely sure?\r\n \r\n Davis looks at his Phone. Ron takes out his SMALL NOTE PAD\r\n out revealing a list of Racial epitaphs he had written down\r\n being on this Investigation. He reads from it to Davis on the\r\n phone.\r\n \r\n ANGLE - SPLIT SCREEN\r\n \r\n Ron Stallworth and Devin Davis.\r\n \r\n RON STALLWORTH (CONT\'D)\r\n Cuz\' dat Niggah Coon, Gator Bait,\r\n Spade, Spook, Sambo, Spear Flippin\',\r\n Jungle Bunny, Mississippi Wind\r\n Chime...Detective is Ron Stallworth\r\n you Redneck, Racist Peckerwood Small\r\n Dick Motherfucker!!!\r\n \r\n CLICK.

COPS ARE ROLLING ON\r\n THE OFFICE FLOOR.\r\n INT. RON\'S APARTMENT - KITCHEN - NIGHT\r\n \r\n Folders of Evidence sit on The Kitchen Table in a stack in\r\n front of Ron. He sips his Lipton Tea and removes from the\r\n FILES THE\r\n \r\n CLOSE - POLAROID\r\n Ron hugged up, between Devin Davis and Jesse Nayyar. He then\r\n looks at The Klan Membership Card shifting in his hands, his\r\n gaze fixated on the words.\r\n \r\n CLOSE - Ron Stallworth\r\n KKK Member in Good Standing\r\n \r\n Patrice comes up from behind.\r\n CLOSE - PATRICE\r\n She pulls out a small handgun from her pocketbook.\r\n \r\n 2 - SHOT - PATRICE AND RON\r\n \r\n PATRICE (O.S.)\r\n Have you Resigned from The KKK?\r\n \r\n RON STALLWORTH\r\n Affirmative.\r\n \r\n PATRICE\r\n Have you handed in your Resignation\r\n as a Undercover Detective for The\r\n Colorado Springs Police Department?\r\n \r\n RON STALLWORTH\r\n Negative. Truth be told I\'ve always\r\n wanted to be a Cop...and I\'m still\r\n for The Liberation for My People.\r\n \r\n PATRICE\r\n My Conscience won\'t let me Sleep with\r\n The Enemy.\r\n \r\n RON STALLWORTH\r\n Enemy? I\'m a Black Man that saved\r\n your life.\r\n \r\n PATRICE\r\n You\'re absolutely right, and I Thank\r\n you for it.\r\n \r\n Patrice Kisses Ron on the cheek. Good Bye. WE HEAR a KNOCK on\r\n Ron\'s DOOR. Ron, who is startled, slowly rises. We HEAR\r\n another KNOCK.\r\n \r\n QUICK FLASHES - of a an OLD TIME KLAN RALLY. Ron moves\r\n quietly to pull out his SERVICE REVOLVER from the COUNTER\r\n DRAWER. WE HEAR ANOTHER KNOCK on the DOOR. Patrice stands\r\n behind him.\r\n \r\n QUICK FLASHES - BLACK BODY HANGING FROM A TREE (STRANGE\r\n FRUIT) Ron slowly moves to the DOOR. Ron has his SERVICE\r\n REVOLVER up and aimed ready to fire. Ron swings open the\r\n DOOR.\r\n ANGLE - HALLWAY\r\n \r\n CU - RON\'S POV\r\n \r\n WE TRACK DOWN THE EMPTY HALLWAY PANNING OUT THE WINDOW.\r\n \r\n CLOSE - RON AND PATRICE\r\n \r\n Looking in the distance: The Rolling Hills surrounding The\r\n Neighborhood lead towards Pike\'s Peak, which sits on the\r\n horizon like a King on A Throne.\r\n \r\n WE SEE: Something Burning.\r\n \r\n CLOSER-- WE SEE a CROSS, its Flames dancing, sending embers\r\n into The BLACK, Colorado Sky.\r\n OMITTED\r\n \r\n EXT.

w422li@uwaterloo.ca Abstract. Recent advances in document image analysis (DIA) have been primarily driven by the application of neural networks. Ideally, research outcomes could be easily deployed in production and extended for further investigation. However, various factors like loosely organized codebases and sophisticated model con\x0cgurations complicate the easy reuse of im- portant innovations by a wide audience. Though there have been on-going e\x0borts to improve reusability and simplify deep learning (DL) model development in disciplines like natural language processing and computer vision, none of them are optimized for challenges in the domain of DIA. This represents a major gap in the existing toolkit, as DIA is central to academic research across a wide range of disciplines in the social sciences and humanities. This paper introduces LayoutParser , an open-source library for streamlining the usage of DL in DIA research and applica- tions. The core LayoutParser library comes with a set of simple and intuitive interfaces for applying and customizing DL models for layout de- tection, character recognition, and many other document processing tasks. To promote extensibility, LayoutParser also incorporates a community platform for sharing both pre-trained models and full document digiti- zation pipelines. We demonstrate that LayoutParser is helpful for both lightweight and large-scale digitization pipelines in real-word use cases. The library is publicly available at https://layout-parser.github.io .

Montoya Instituto de Matem´atica, Estat´ıstica e Computa¸c˜ao Cient´ıfica, In [3] we proved that, under suitable conditions, on a very general codimension s quasi- smooth intersection subvariety X in a projective toric orbifold P d Σ with d + s = 2 ( k + 1 ) the Hodge conjecture holds, that is, every ( p, p ) -cohomology class, under the Poincar´e duality is a rational linear combination of fundamental classes of algebraic subvarieties of X . The proof of the above-mentioned result relies, for p ≠ d + 1 − s , on a Lefschetz Keywords: (1,1)- Lefschetz theorem, Hodge conjecture, toric varieties, complete intersection Email: wmontoya@ime.unicamp.br theorem ([7]) and the Hard Lefschetz theorem for projective orbifolds ([11]). When p = d + 1 − s the proof relies on the Cayley trick, a trick which associates to X a quasi-smooth hypersurface Y in a projective vector bundle, and the Cayley Proposition (4.3) which gives an isomorphism of some primitive cohomologies (4.2) of X and Y . The Cayley trick, following the philosophy of Mavlyutov in [7], reduces results known for quasi-smooth hypersurfaces to quasi-smooth intersection subvarieties. The idea in this paper goes the other way around, we translate some results for quasi-smooth intersection subvarieties to Acknowledgement.

Let M be a free abelian group of rank d , let N = Hom ( M, Z ) , and N R = N ⊗ Z R . if there exist k linearly independent primitive elements e , . . . , e k ∈ N such that σ = { µ e + ⋯ + µ k e k } . • The generators e i are integral if for every i and any nonnegative rational number µ the product µe i is in N only if µ is an integer. • Given two rational simplicial cones σ , σ ′ one says that σ ′ is a face of σ ( σ ′ < σ ) if the set of integral generators of σ ′ is a subset of the set of integral generators of σ . • A finite set Σ = { σ , . . . , σ t } of rational simplicial cones is called a rational simplicial complete d -dimensional fan if: all faces of cones in Σ are in Σ ; if σ, σ ′ ∈ Σ then σ ∩ σ ′ < σ and σ ∩ σ ′ < σ ′ ; N R = σ ∪ ⋅ ⋅ ⋅ ∪ σ t . A rational simplicial complete d -dimensional fan Σ defines a d -dimensional toric variety P d Σ having only orbifold singularities which we assume to be projective. Moreover, T ∶ = N ⊗ Z C ∗ ≃ ( C ∗ ) d is the torus action on P d Σ . We denote by Σ ( i ) the i -dimensional cones For a cone σ ∈ Σ, ˆ σ is the set of 1-dimensional cone in Σ that are not contained in σ and x ˆ σ ∶ = ∏ ρ ∈ ˆ σ x ρ is the associated monomial in S . Definition 2.2. The irrelevant ideal of P d Σ is the monomial ideal B Σ ∶ =< x ˆ σ ∣ σ ∈ Σ > and the zero locus Z ( Σ ) ∶ = V ( B Σ ) in the affine space A d ∶ = Spec ( S ) is the irrelevant locus. Proposition 2.3 (Theorem 5.1.11 [5]) . The toric variety P d Σ is a categorical quotient A d ∖ Z ( Σ ) by the group Hom ( Cl ( Σ ) , C ∗ ) and the group action is induced by the Cl ( Σ ) - grading of S . Now we give a brief introduction to complex orbifolds and we mention the needed theorems for the next section. Namely: de Rham theorem and Dolbeault theorem for complex orbifolds. Definition 2.4. A complex orbifold of complex dimension d is a singular complex space whose singularities are locally isomorphic to quotient singularities C d / G , for finite sub- groups G ⊂ Gl ( d, C ) . Definition 2.5. A differential form on a complex orbifold Z is defined locally at z ∈ Z as a G -invariant differential form on C d where G ⊂ Gl ( d, C ) and Z is locally isomorphic to d Roughly speaking the local geometry of orbifolds reduces to local G -invariant geometry. We have a complex of differential forms ( A ● ( Z ) , d ) and a double complex ( A ● , ● ( Z ) , ∂, ¯ ∂ ) of bigraded differential forms which define the de Rham and the Dolbeault cohomology groups (for a fixed p ∈ N ) respectively: (1,1)-Lefschetz theorem for projective toric orbifolds Definition 3.1. A subvariety X ⊂ P d Σ is quasi-smooth if V ( I X ) ⊂ A #Σ ( 1 ) is smooth outside Example 3.2 . Quasi-smooth hypersurfaces or more generally quasi-smooth intersection sub- Example 3.2 . Quasi-smooth hypersurfaces or more generally quasi-smooth intersection sub- varieties are quasi-smooth subvarieties (see [2] or [7] for more details). Remark 3.3 . Quasi-smooth subvarieties are suborbifolds of P d Σ in the sense of Satake in [8]. Intuitively speaking they are subvarieties whose only singularities come from the ambient Proof. From the exponential short exact sequence we have a long exact sequence in cohomology H 1 (O ∗ X ) → H 2 ( X, Z ) → H 2 (O X ) ≃ H 0 , 2 ( X ) where the last isomorphisms is due to Steenbrink in [9]. Now, it is enough to prove the commutativity of the next diagram where the last isomorphisms is due to Steenbrink in [9]. Now, H 2 ( X, Z ) / / H 2 ( X, O X ) ≃ Dolbeault H 2 ( X, C ) deRham ≃ H 2 dR ( X, C ) / / H 0 , 2 ¯ ∂ ( X ) of the proof follows as the ( 1 , 1 ) -Lefschetz theorem in [6]. Remark 3.5 . For k = 1 and P d Σ as the projective space, we recover the classical ( 1 , 1 ) - Lefschetz theorem. By the Hard Lefschetz Theorem for projective orbifolds (see [11] for details) we By the Hard Lefschetz Theorem for projective orbifolds (see [11] for details) we get an isomorphism of cohomologies : given by the Lefschetz morphism and since it is a morphism of Hodge structures, we have: H 1 , 1 ( X, Q ) ≃ H dim X − 1 , dim X − 1 ( X, Q ) Corollary 3.6. If the dimension of X is 1 , 2 or 3 . The Hodge conjecture holds on X Proof. If the dim C X = 1 the result is clear by the Hard Lefschetz theorem for projective orbifolds. The dimension 2 and 3 cases are covered by Theorem 3.5 and the Hard Lefschetz. Cayley trick and Cayley proposition The Cayley trick is a way to associate to a quasi-smooth intersection subvariety a quasi- smooth hypersurface. Let L 1 , . . . , L s be line bundles on P d Σ and let π ∶ P ( E ) → P d Σ be the projective space bundle associated to the vector bundle E = L 1 ⊕ ⋯ ⊕ L s . It is known that P ( E ) is a ( d + s − 1 ) -dimensional simplicial toric variety whose fan depends on the degrees of the line bundles and the fan Σ. Furthermore, if the Cox ring, without considering the grading, of P d Σ is C [ x 1 , . . . , x m ] then the Cox ring of P ( E ) is Moreover for X a quasi-smooth intersection subvariety cut off by f 1 , . . . , f s with deg ( f i ) = [ L i ] we relate the hypersurface Y cut off by F = y 1 f 1 + ⋅ ⋅ ⋅ + y s f s which turns out to be quasi-smooth. For more details see Section 2 in [7]. We will denote P ( E ) as P d + s − 1 Σ ,X to keep track of its relation with X and P d Σ . The following is a key remark. Remark 4.1 . There is a morphism ι ∶ X → Y ⊂ P d + s − 1 Σ ,X . Moreover every point z ∶ = ( x, y ) ∈ Y with y ≠ 0 has a preimage. Hence for any subvariety W = V ( I W ) ⊂ X ⊂ P d Σ there exists W ′ ⊂ Y ⊂ P d + s − 1 Σ ,X such that π ( W ′ ) = W , i.e., W ′ = { z = ( x, y ) ∣ x ∈ W } . For X ⊂ P d Σ a quasi-smooth intersection variety the morphism in cohomology induced by the inclusion i ∗ ∶ H d − s ( P d Σ , C ) → H d − s ( X, C ) is injective by Proposition 1.4 in [7]. Definition 4.2. The primitive cohomology of H d − s prim ( X ) is the quotient H d − s ( X, C )/ i ∗ ( H d − s ( P d Σ , C )) and H d − s prim ( X, Q ) with rational coefficients. H d − s ( P d Σ , C ) and H d − s ( X, C ) have pure Hodge structures, and the morphism i ∗ is com- patible with them, so that H d − s prim ( X ) gets a pure Hodge structure. The next Proposition is the Cayley proposition. Proposition 4.3. [Proposition 2.3 in [3] ] Let X = X 1 ∩⋅ ⋅ ⋅∩ X s be a quasi-smooth intersec- tion subvariety in P d Σ cut off by homogeneous polynomials f 1 . . . f s . Then for p ≠ d + s − 1 2 , d + s − 3 2 Remark 4.5 . The above isomorphisms are also true with rational coefficients since H ● ( X, C ) = H ● ( X, Q ) ⊗ Q C . See the beginning of Section 7.1 in [10] for more details. Theorem 5.1. Let Y = { F = y 1 f 1 + ⋯ + y k f k = 0 } ⊂ P 2 k + 1 Σ ,X be the quasi-smooth hypersurface associated to the quasi-smooth intersection surface X = X f 1 ∩ ⋅ ⋅ ⋅ ∩ X f k ⊂ P k + 2 Σ . Then on Y the Hodge conjecture holds. the Hodge conjecture holds. Proof. If H k,k prim ( X, Q ) = 0 we are done. So let us assume H k,k prim ( X, Q ) ≠ 0. By the Cayley proposition H k,k prim ( Y, Q ) ≃ H 1 , 1 prim ( X, Q ) and by the ( 1 , 1 ) -Lefschetz theorem for projective toric orbifolds there is a non-zero algebraic basis λ C 1 , . . . , λ C n with rational coefficients of H 1 , 1 prim ( X, Q ) , that is, there are n ∶ = h 1 , 1 prim ( X, Q ) algebraic curves C 1 , . . . , C n in X such that under the Poincar´e duality the class in homology [ C i ] goes to λ C i , [ C i ] ↦ λ C i . Recall that the Cox ring of P k + 2 is contained in the Cox ring of P 2 k + 1 Σ ,X without considering the grading. Considering the grading we have that if α ∈ Cl ( P k + 2 Σ ) then ( α, 0 ) ∈ Cl ( P 2 k + 1 Σ ,X ) . So the polynomials defining C i ⊂ P k + 2 Σ can be interpreted in P 2 k + 1 X, Σ but with different degree. Moreover, by Remark 4.1 each C i is contained in Y = { F = y 1 f 1 + ⋯ + y k f k = 0 } and furthermore it has codimension k . Claim: { C i } ni = 1 is a basis of prim ( ) . It is enough to prove that λ C i is different from zero in H k,k prim ( Y, Q ) or equivalently that the cohomology classes { λ C i } ni = 1 do not come from the ambient space. By contradiction, let us assume that there exists a j and C ⊂ P 2 k + 1 Σ ,X such that λ C ∈ H k,k ( P 2 k + 1 Σ ,X , Q ) with i ∗ ( λ C ) = λ C j or in terms of homology there exists a ( k + 2 ) -dimensional algebraic subvariety V ⊂ P 2 k + 1 Σ ,X such that V ∩ Y = C j so they are equal as a homology class of P 2 k + 1 Σ ,X ,i.e., [ V ∩ Y ] = [ C j ] . It is easy to check that π ( V ) ∩ X = C j as a subvariety of P k + 2 Σ where π ∶ ( x, y ) ↦ x . Hence [ π ( V ) ∩ X ] = [ C j ] which is equivalent to say that λ C j comes from P k + 2 Σ which contradicts the choice of [ C j ] . Remark 5.2 . Into the proof of the previous theorem, the key fact was that on X the Hodge conjecture holds and we translate it to Y by contradiction. So, using an analogous argument we have: argument we have: Proposition 5.3. Let Y = { F = y 1 f s +⋯+ y s f s = 0 } ⊂ P 2 k + 1 Σ ,X be the quasi-smooth hypersurface associated to a quasi-smooth intersection subvariety X = X f 1 ∩ ⋅ ⋅ ⋅ ∩ X f s ⊂ P d Σ such that d + s = 2 ( k + 1 ) . If the Hodge conjecture holds on X then it holds as well on Y . Corollary 5.4. If the dimension of Y is 2 s − 1 , 2 s or 2 s + 1 then the Hodge conjecture holds on Y . Proof.

The dhSegment [22] utilizes fully convolutional networks [20] for segmen- tation tasks on historical documents. Object detection-based methods like Faster R-CNN [28] and Mask R-CNN [12] are used for identifying document elements [38] and detecting tables [30, 26]. Most recently, Graph Neural Networks [29] have also been used in table detection [27]. However, these models are usually implemented individually and there is no unified framework to load and use such models. There has been a surge of interest in creating open-source tools for document image processing: a search of document image analysis in Github leads to 5M relevant code pieces 6; yet most of them rely on traditional rule-based methods or provide limited functionalities. The closest prior research to our work is the OCR-D project7, which also tries to build a complete toolkit for DIA. However, similar to the platform developed by Neudecker et al. [21], it is designed for analyzing historical documents, and provides no supports for recent DL models. The DocumentLayoutAnalysis project8 focuses on processing born-digital PDF documents via analyzing the stored PDF data. Repositories like DeepLayout9 and Detectron2-PubLayNet10 are individual deep learning models trained on layout analysis datasets without support for the full DIA pipeline. The Document Analysis and Exploitation (DAE) platform [15] and the DeepDIVA project [2] aim to improve the reproducibility of DIA methods (or DL models), yet they are not actively maintained. OCR engines like Tesseract [14], easyOCR11 and paddleOCR12 usually do not come with comprehensive functionalities for other DIA tasks like layout analysis. Recent years have also seen numerous efforts to create libraries for promoting reproducibility and reusability in the field of DL. Libraries like Dectectron2 [35], 6 The number shown is obtained by specifying the search type as ‘code’. 7 https://ocr-d.de/en/about 8 https://github.com/BobLd/DocumentLayoutAnalysis 9 https://github.com/leonlulu/DeepLayout 10 https://github.com/hpanwar08/detectron2 11 https://github.com/JaidedAI/EasyOCR 12 https://github.com/PaddlePaddle/PaddleOCR 4 Z. Shen et al. Fig. 1: The overall architecture of LayoutParser. For an input document image, the core LayoutParser library provides a set of off-the-shelf tools for layout detection, OCR, visualization, and storage, backed by a carefully designed layout data structure. LayoutParser also supports high level customization via efficient layout annotation and model training functions. These improve model accuracy on the target samples. The community platform enables the easy sharing of DIA models and whole digitization pipelines to promote reusability and reproducibility. A collection of detailed documentation, tutorials and exemplar projects make LayoutParser easy to learn and use. AllenNLP [8] and transformers [34] have provided the community with complete DL-based support for developing and deploying models for general computer vision and natural language processing problems. LayoutParser, on the other hand, specializes specifically in DIA tasks. LayoutParser is also equipped with a community platform inspired by established model hubs such as Torch Hub [23] and TensorFlow Hub [1]. It enables the sharing of pretrained models as well as full document processing pipelines that are unique to DIA tasks. There have been a variety of document data collections to facilitate the development of DL models. Some examples include PRImA [3](magazine layouts), PubLayNet [38](academic paper layouts), Table Bank [18](tables in academic papers), Newspaper Navigator Dataset [16, 17](newspaper figure layouts) and HJDataset [31](historical Japanese document layouts).

\n\n\n\nGetting Started\nModules\nUse Cases\nReference Docs\nLangChain Ecosystem\nAdditional Resources\n\n\n\n\n\n\n\n\nWelcome to LangChain#\nLarge language models (LLMs) are emerging as a transformative technology, enabling\ndevelopers to build applications that they previously could not.\nBut using these LLMs in isolation is often not enough to\ncreate a truly powerful app - the real power comes when you are able to\ncombine them with other sources of computation or knowledge.\nThis library is aimed at assisting in the development of those types of applications. Common examples of these types of applications include:\n❓ Question Answering over specific documents\n\nDocumentation\nEnd-to-end Example: Question Answering over Notion Database\n\n💬 Chatbots\n\nDocumentation\nEnd-to-end Example: Chat-LangChain\n\n🤖 Agents\n\nDocumentation\nEnd-to-end Example: GPT+WolframAlpha\n\n\nGetting Started#\nCheckout the below guide for a walkthrough of how to get started using LangChain to create an Language Model application.\n\nGetting Started Documentation\n\n\n\n\n\nModules#\nThere are several main modules that LangChain provides support for.\nFor each module we provide some examples to get started, how-to guides, reference docs, and conceptual guides.\nThese modules are, in increasing order of complexity:\n\nPrompts: This includes prompt management, prompt optimization, and prompt serialization.\nLLMs: This includes a generic interface for all LLMs, and common utilities for working with LLMs.\nDocument Loaders: This includes a standard interface for loading documents, as well as specific integrations to all types of text data sources.\nUtils: Language models are often more powerful when interacting with other sources of knowledge or computation. This can include Python REPLs, embeddings, search engines, and more. LangChain provides a large collection of common utils to use in your application.\nChains: Chains go beyond just a single LLM call, and are sequences of calls (whether to an LLM or a different utility). LangChain provides a standard interface for chains, lots of integrations with other tools, and end-to-end chains for common applications.\nIndexes: Language models are often more powerful when combined with your own text data - this module covers best practices for doing exactly that.\nAgents: Agents involve an LLM making decisions about which Actions to take, taking that Action, seeing an Observation, and repeating that until done. LangChain provides a standard interface for agents, a selection of agents to choose from, and examples of end to end agents.\nMemory: Memory is the concept of persisting state between calls of a chain/agent. LangChain provides a standard interface for memory, a collection of memory implementations, and examples of chains/agents that use memory.\nChat: Chat models are a variation on Language Models that expose a different API - rather than working with raw text, they work with messages. LangChain provides a standard interface for working with them and doing all the same things as above.\n\n\n\n\n\nUse Cases#\nThe above modules can be used in a variety of ways. LangChain also provides guidance and assistance in this. Below are some of the common use cases LangChain supports.\n\nAgents: Agents are systems that use a language model to interact with other tools. These can be used to do more grounded question/answering, interact with APIs, or even take actions.\nChatbots: Since language models are good at producing text, that makes them ideal for creating chatbots.\nData Augmented Generation: Data Augmented Generation involves specific types of chains that first interact with an external datasource to fetch data to use in the generation step. Examples of this include summarization of long pieces of text and question/answering over specific data sources.\nQuestion Answering: Answering questions over specific documents, only utilizing the information in those documents to construct an answer. A type of Data Augmented Generation.\nSummarization: Summarizing longer documents into shorter, more condensed chunks of information. A type of Data Augmented Generation.\nQuerying Tabular Data: If you want to understand how to use LLMs to query data that is stored in a tabular format (csvs, SQL, dataframes, etc) you should read this page.\nEvaluation: Generative models are notoriously hard to evaluate with traditional metrics. One new way of evaluating them is using language models themselves to do the evaluation. LangChain provides some prompts/chains for assisting in this.\nGenerate similar examples: Generating similar examples to a given input. This is a common use case for many applications, and LangChain provides some prompts/chains for assisting in this.\nCompare models: Experimenting with different prompts, models, and chains is a big part of developing the best possible application. The ModelLaboratory makes it easy to do so.\n\n\n\n\n\nReference Docs#\nAll of LangChain’s reference documentation, in one place. Full documentation on all methods, classes, installation methods, and integration setups for LangChain.\n\nReference Documentation\n\n\n\n\n\nLangChain Ecosystem#\nGuides for how other companies/products can be used with LangChain\n\nLangChain Ecosystem\n\n\n\n\n\nAdditional Resources#\nAdditional collection of resources we think may be useful as you develop your application!\n\nLangChainHub: The LangChainHub is a place to share and explore other prompts, chains, and agents.\nGlossary: A glossary of all related terms, papers, methods, etc. Whether implemented in LangChain or not!\nGallery: A collection of our favorite projects that use LangChain. Useful for finding inspiration or seeing how things were done in other applications.\nDeployments: A collection of instructions, code snippets, and template repositories for deploying LangChain apps.\nDiscord: Join us on our Discord to discuss all things LangChain!\nTracing: A guide on using tracing in LangChain to visualize the execution of chains and agents.\nProduction Support: As you move your LangChains into production, we’d love to offer more comprehensive support. Please fill out this form and we’ll set up a dedicated support Slack channel.\n\n\n\n\n\n\n\n\n\n\n\nnext\nQuickstart Guide\n\n\n\n\n\n\n\n\n\n Contents\n \n\n\nGetting Started\nModules\nUse

\n\n\n\nGetting Started\nModules\nUse Cases\nReference Docs\nLangChain Ecosystem\nAdditional Resources\n\n\n\n\n\n\n\n\nWelcome to LangChain#\nLangChain is a framework for developing applications powered by language models. We believe that the most powerful and differentiated applications will not only call out to a language model via an API, but will also:\n\nBe data-aware: connect a language model to other sources of data\nBe agentic: allow a language model to interact with its environment\n\nThe LangChain framework is designed with the above principles in mind.\nThis is the Python specific portion of the documentation. For a purely conceptual guide to LangChain, see here. For the JavaScript documentation, see here.\n\nGetting Started#\nCheckout the below guide for a walkthrough of how to get started using LangChain to create an Language Model application.\n\nGetting Started Documentation\n\n\n\n\n\nModules#\nThere are several main modules that LangChain provides support for.\nFor each module we provide some examples to get started, how-to guides, reference docs, and conceptual guides.\nThese modules are, in increasing order of complexity:\n\nModels: The various model types and model integrations LangChain supports.\nPrompts: This includes prompt management, prompt optimization, and prompt serialization.\nMemory: Memory is the concept of persisting state between calls of a chain/agent. LangChain provides a standard interface for memory, a collection of memory implementations, and examples of chains/agents that use memory.\nIndexes: Language models are often more powerful when combined with your own text data - this module covers best practices for doing exactly that.\nChains: Chains go beyond just a single LLM call, and are sequences of calls (whether to an LLM or a different utility). LangChain provides a standard interface for chains, lots of integrations with other tools, and end-to-end chains for common applications.\nAgents: Agents involve an LLM making decisions about which Actions to take, taking that Action, seeing an Observation, and repeating that until done. LangChain provides a standard interface for agents, a selection of agents to choose from, and examples of end to end agents.\n\n\n\n\n\nUse Cases#\nThe above modules can be used in a variety of ways. LangChain also provides guidance and assistance in this. Below are some of the common use cases LangChain supports.\n\nPersonal Assistants: The main LangChain use case. Personal assistants need to take actions, remember interactions, and have knowledge about your data.\nQuestion Answering: The second big LangChain use case. Answering questions over specific documents, only utilizing the information in those documents to construct an answer.\nChatbots: Since language models are good at producing text, that makes them ideal for creating chatbots.\nQuerying Tabular Data: If you want to understand how to use LLMs to query data that is stored in a tabular format (csvs, SQL, dataframes, etc) you should read this page.\nInteracting with APIs: Enabling LLMs to interact with APIs is extremely powerful in order to give them more up-to-date information and allow them to take actions.\nExtraction: Extract structured information from text.\nSummarization: Summarizing longer documents into shorter, more condensed chunks of information. A type of Data Augmented Generation.\nEvaluation: Generative models are notoriously hard to evaluate with traditional metrics. One new way of evaluating them is using language models themselves to do the evaluation. LangChain provides some prompts/chains for assisting in this.\n\n\n\n\n\nReference Docs#\nAll of LangChain’s reference documentation, in one place. Full documentation on all methods, classes, installation methods, and integration setups for LangChain.\n\nReference Documentation\n\n\n\n\n\nLangChain Ecosystem#\nGuides for how other companies/products can be used with LangChain\n\nLangChain Ecosystem\n\n\n\n\n\nAdditional Resources#\nAdditional collection of resources we think may be useful as you develop your application!\n\nLangChainHub: The LangChainHub is a place to share and explore other prompts, chains, and agents.\nGlossary: A glossary of all related terms, papers, methods, etc. Whether implemented in LangChain or not!\nGallery: A collection of our favorite projects that use LangChain. Useful for finding inspiration or seeing how things were done in other applications.\nDeployments: A collection of instructions, code snippets, and template repositories for deploying LangChain apps.\nTracing: A guide on using tracing in LangChain to visualize the execution of chains and agents.\nModel Laboratory: Experimenting with different prompts, models, and chains is a big part of developing the best possible application. The ModelLaboratory makes it easy to do so.\nDiscord: Join us on our Discord to discuss all things LangChain!\nProduction Support: As you move your LangChains into production, we’d love to offer more comprehensive support. Please fill out this form and we’ll set up a dedicated support Slack channel.\n\n\n\n\n\n\n\n\n\n\n\nnext\nQuickstart Guide\n\n\n\n\n\n\n\n\n\n Contents\n \n\n\nGetting Started\nModules\nUse Cases\nReference Docs\nLangChain Ecosystem\nAdditional Resources\n\n\n\n\n\n\n\n\n\nBy Harrison Chase\n\n\n\n\n \n © Copyright 2023, Harrison Chase.\n \n\n\n\n\n Last updated on Mar 27, 2023.\n \n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n', lookup_str='', metadata={'source': 'https://python.langchain.com/en/latest/', 'loc': 'https://python.langchain.com/en/latest/', 'lastmod': '2023-03-27T22:50:49.790324+00:00', 'changefreq': 'daily', 'priority': '0.9'}, lookup_index=0) ``` diff --git a/pages/modules/indexes/document_loaders/examples/slack_directory.mdx b/pages/modules/indexes/document_loaders/examples/slack_directory.mdx index 71c3774..ca7bfbb 100644 --- a/pages/modules/indexes/document_loaders/examples/slack_directory.mdx +++ b/pages/modules/indexes/document_loaders/examples/slack_directory.mdx @@ -35,11 +35,11 @@ import Head from 'next/head' 复制.zip文件的路径，并将其分配为下面的LOCAL_ZIPFILE。 -``` python +```python from langchain.document_loaders import SlackDirectoryLoader ``` -``` python +```python # 可选择设置你的Slack URL，这将在文档中为您提供正确的URL。 SLACK_WORKSPACE_URL = "https://xxx.slack.com" LOCAL_ZIPFILE = "" # 将本地路径粘贴到Slack zip文件中。 @@ -47,7 +47,7 @@ LOCAL_ZIPFILE = "" # 将本地路径粘贴到Slack zip文件中。 loader = SlackDirectoryLoader(LOCAL_ZIPFILE, SLACK_WORKSPACE_URL) ``` -``` python +```python docs = loader.load() docs ``` \ No newline at end of file diff --git a/pages/modules/indexes/document_loaders/examples/srt.mdx b/pages/modules/indexes/document_loaders/examples/srt.mdx index f5e0323..35396f9 100644 --- a/pages/modules/indexes/document_loaders/examples/srt.mdx +++ b/pages/modules/indexes/document_loaders/examples/srt.mdx @@ -35,7 +35,7 @@ import Head from 'next/head' -``` +```python from langchain.document_loaders import SRTLoader ``` @@ -49,7 +49,7 @@ from langchain.document_loaders import SRTLoader -``` +```python loader = SRTLoader("example_data/Star_Wars_The_Clone_Wars_S06E07_Crisis_at_the_Heart.srt") ``` @@ -63,7 +63,7 @@ loader = SRTLoader("example_data/Star_Wars_The_Clone_Wars_S06E07_Crisis_at_the_H -``` +```python docs = loader.load() ``` @@ -77,7 +77,7 @@ docs = loader.load() -``` +```python docs[0].page_content[:100] ``` @@ -89,7 +89,7 @@ docs[0].page_content[:100] -``` +```python 'Corruption discovered\nat the core of the Banking Clan!

In this case, it’s very handy to be able to partial the prompt with a function that always returns the current date. +另一个常见的用途是使用函数部分化。这种情况的用例是当您知道您总是想以一种常见的方式获取一个变量时。 +这个例子最好的例子是日期或时间。假如你有一个Prompt，总是要有当前日期。 + +你不能在Prompt中硬编码它，而且将它与其他输入变量一起传递有点麻烦。 + +在这种情况下，使用一个总是返回当前日期的函数对Prompt进行部分化非常方便。 ```python from datetime import datetime @@ -90,9 +106,7 @@ print(partial_prompt.format(adjective="funny")) Tell me a funny joke about the day 02/27/2023, 22:15:16 ``` - -You can also just initialize the prompt with the partialed variables, which often makes more sense in this workflow. - +在这种工作流中，您也可以使用部分变量初始化Prompt，这通常更有意义。 ```python prompt = PromptTemplate( template="Tell me a {adjective} joke about the day {date}", diff --git a/pages/use_cases/evaluation/qa_benchmarking_sota.mdx b/pages/use_cases/evaluation/qa_benchmarking_sota.mdx index d6cc082..d63d0f8 100644 --- a/pages/use_cases/evaluation/qa_benchmarking_sota.mdx +++ b/pages/use_cases/evaluation/qa_benchmarking_sota.mdx @@ -33,9 +33,6 @@ import Head from 'next/head' 在这里，我们将讨论如何在国情咨文演讲中对问答任务的性能进行基准测试。 - It is highly reccomended that you do any evaluation/benchmarking with tracing enabled.

The stop loss and profit target are calculated based on the stop_loss_percent and profit_target_percent variables, respectively. The buy and sell prices are stored in the buy_price and sell_price variables, respectively. If the sell price is less than or equal to the stop loss, the profit or loss is set to -stop_loss. If the sell price is greater than or equal to the profit target, the profit or loss is set to profit_target. Otherwise, the profit or loss is calculated as (sell_price - buy_price) / buy_price.

One example of an unexpected issue I faced was when one of the vendors didn't show up on time. To handle this, I quickly contacted a backup vendor and was able to get everything back on track. It's always important to have a backup plan in case things don't go as planned. Do you have any other questions about event planning?" + +Tommie said "Thank you for sharing that with me, Eve. It's really helpful to hear how you handled unexpected issues like that. Can you give me an example of how you communicated with your team to ensure everyone was on the same page during an event?" + +Eve said "Sure, Tommie. One thing I did to ensure everyone was on the same page was to have regular check-ins and meetings with the team leading up to the event.

I mean, have you seen the size of the chairs these days? They're practically begging us to sit in them all day. And as for exercise routines, let's just say I've never been one for the gym. But I can definitely see the appeal of sitting competitions. It's like a sport for the rest of us. Plus, I think it's a great way to bond with friends and family. Who needs a game of catch when you can have a sit-off? + + + + + + Stop? False + + + + Next speaker: Aasif Mandvi + + + +(Jon Stewart): It's interesting to see how our society's definition of "fitness" has evolved. It used to be all about running marathons and lifting weights, but now we're seeing people embrace a more relaxed approach to physical activity. Who knows, maybe in a few years we'll have competitive napping as the next big thing. *leans back in chair* I could definitely get behind that. Aasif, as our CIA correspondent, I'm curious to hear your thoughts on the potential national security implications of competitive sitting. Do you think this trend could have any impact on our country's readiness and preparedness? + + + + + +(Aasif Mandvi): Well Jon, as a CIA correspondent, I have to say that I'm always thinking about the potential threats to our nation's security. And while competitive sitting may seem harmless, there could be some unforeseen consequences. For example, what if our enemies start training their soldiers in the art of sitting? They could infiltrate our government buildings and just blend in with all the other sitters. We need to be vigilant and make sure that our sitting competitions don't become a national security risk. *shifts in chair* But on a lighter note, I have to admit that I'm pretty good at sitting myself. Maybe I should start training for the next competition. + + + + + + Stop? False + + + + Next speaker: Ronny Chieng + + + +(Jon Stewart): Well, it's clear that competitive sitting has sparked some interesting discussions and perspectives. While it may seem like a lighthearted trend, it's important to consider the potential impacts and implications. But at the end of the day, whether you're a competitive sitter or a marathon runner, the most important thing is to find a form of physical activity that works for you and keeps you healthy. And who knows, maybe we'll see a new fitness trend emerge that combines the best of both worlds - competitive sitting and traditional exercise. *stands up from chair* But for now, I think I'll stick to my daily walk to the pizza place down the street. Ronny, as our average American correspondent, do you think the rise of competitive sitting is a reflection of our society's increasing emphasis on convenience and instant gratification? + + + + + +(Ronny Chieng): Absolutely, Jon. We live in a world where everything is at our fingertips, and we expect things to be easy and convenient. So it's no surprise that people are drawn to a fitness trend that requires minimal effort and can be done from the comfort of their own homes. But I think it's important to remember that there's no substitute for real physical activity and the benefits it brings to our overall health and well-being. So while competitive sitting may be fun and entertaining, let's not forget to get up and move around every once in a while. *stands up from chair and stretches* + + + + + + Stop? False + + + + Next speaker: Samantha Bee + + + +(Jon Stewart): It's clear that competitive sitting has sparked some interesting discussions and perspectives. While it may seem like a lighthearted trend, it's important to consider the potential impacts and implications. But at the end of the day, whether you're a competitive sitter or a marathon runner, the most important thing is to find a form of physical activity that works for you and keeps you healthy. That's a great point, Ronny. Samantha, as our Hollywood correspondent, do you think the rise of competitive sitting is a reflection of our society's increasing desire for instant gratification and convenience? Or is there something deeper at play here? + + + + + +(Samantha Bee): Oh, Jon, you know I love a good conspiracy theory. And let me tell you, I think there's something more sinister at play here. I mean, think about it - what if the government is behind this whole competitive sitting trend? They want us to be lazy and complacent so we don't question their actions. It's like the ultimate mind control. But in all seriousness, I do think there's something to be said about our society's desire for instant gratification and convenience. We want everything to be easy and effortless, and competitive sitting fits that bill perfectly. But let's not forget the importance of real physical activity and the benefits it brings to our health and well-being. *stands up from chair and does a few stretches* + + + + + + Stop? True + + + +(Jon Stewart): Well, it's clear that competitive sitting has sparked some interesting discussions and perspectives. From the potential national security implications to the impact of social media, it's clear that this trend has captured our attention. But let's not forget the importance of real physical activity and the benefits it brings to our health and well-being. Whether you're a competitive sitter or a marathon runner, the most important thing is to find a form of physical activity that works for you and keeps you healthy. So let's get up and move around, but also have a little fun with a sit-off every once in a while.

The stop loss and profit target are calculated based on the stop_loss_percent and profit_target_percent variables, respectively. The buy and sell prices are stored in the buy_price and sell_price variables, respectively. If the sell price is less than or equal to the stop loss, the profit or loss is set to -stop_loss. If the sell price is greater than or equal to the profit target, the profit or loss is set to profit_target. Otherwise, the profit or loss is calculated as (sell_price - buy_price) / buy_price. Next request. + + +AI User (Stock Trader): + +Instruction: Calculate the total profit or loss for all trades. +Input: None. + + +AI Assistant (Python Programmer): + +Solution: We can calculate the total profit or loss for all trades by summing the values in the 'pnl' column of the DataFrame.

+**答案**：favCountParams是一个可选的ThriftLinearFeatureRankingParams实例，它代表了与排名过程中“收藏数”功能相关的参数。它用于控制在排名推文时收藏数功能的权重。收藏数是用户标记推文为收藏的次数，因此在推文排名中被认为是一个重要的信号。通过使用favCountParams，系统可以调整收藏数的重要性，同时计算推文的最终排名分数。 + + +-> **问题**：从代码中看不清它是喜欢和书签还是不清楚？ + + +**答案**：从提供的代码中，不清楚收藏数指标是否由喜欢和书签的总和确定。收藏数在代码中被提到，但没有明确指出它如何根据喜欢和书签计算。 + + +-> **问题**：哪些主要负面修饰符会降低您的线性排名参数？ + + +**答案**：在给定的代码中，主要降低线性排名参数的负面修饰符是： + + +1. `scoringData.querySpecificScore`: ：这个分数调整是基于query-specific的信息。如果它的值为负，它会降低线性排名参数。 + +2. `scoringData.authorSpecificScore`: 本次评分调整基于作者具体信息。如果它的值为负，它也会降低线性排名参数。 + + + + + +请注意，由于未提供这些负修饰符的确定代码，我无法提供有关其精确计算的更多信息。 + + + + +-> **问题**: 你如何被分配到SimClusters？ + + + + +**答案**: SimClusters的分配是通过基于Metropolis-Hastings采样的社区检测算法在制作者-制作者相似度图上运行实现的。该图是通过计算关注每个制作者的用户之间的余弦相似度得出的。该算法识别具有相似关注者的制作者的群体或群集，并采用参数*k*来指定要检测的社区数。 + + + + +在社区检测之后，不同的用户和内容在这些已识别的SimClusters中表示为稀疏可解释向量。得到的SimClusters嵌入可以用于各种推荐任务。 + + + + +-> **问题**: 从一个SimClusters迁移到另一个SimClusters需要什么？ + + + + +**答案**: 要从一个SimClusters表示迁移到另一个表示，您可以按照以下一般步骤:进行操作： + + + + +1. **准备新表示 Prepare the new representation**：使用聚类算法、相似性度量或其他模型参数的任何必要更新或更改来创建新的 SimClusters 表示。确保根据需要正确存储和索引此新表示。 + +2. **更新相关代码和配置**: 修改相关代码和配置文件，以引用新的SimClusters表示。这可能涉及更新路径或数据集名称以指向新的表示，以及根据需要更改代码以使用新的聚类方法或相似性函数。 +3. **测试新表示**: 在将更改部署到生产前，彻底测试新的SimClusters表示，以确保其有效性和稳定性。这可能涉及运行离线作业，如候选生成和标签候选项，验证输出，以及使用评估工具在评估环境中测试新表示，例如TweetSimilarityEvaluationAdhocApp。 +4. **部署更改**: 一旦测试和验证了新的表示，部署更改到生产环境中。这可能涉及创建一个zip文件，将其上传到packer中，然后使用Aurora进行调度。请确保监视系统，以确保在表示之间平稳过渡，并验证新的表示在推荐中按预期使用。 +5. **监视和评估新的表示**: 在部署新的表示后，继续监视其对推荐的性能和影响。注意任何改进或问题，并准备根据需要迭代新的表示。始终确保结果和性能指标与系统的目标和目的相一致。 + + + + +-> **Question**: 问题：我在集群中得到了多少提升？ How much do I get boosted within my cluster? + + + + + +**回答**: 在SimClusters表现中，无法确定您的内容在群集内的确切提升数量，而不具有关于您的内容及其参与度度量的具体数据。然而，一些因素（如收藏得分和关注得分以及其他参与度信号和SimCluster计算）均会影响内容的提升。 + + + + +-> **问题**: Heavy Ranker是如何工作的。它的主要输入是什么？ + + + + +**回答**: Heavy Ranker是一种机器学习模型，对于推荐算法中的候选者排名和评分起着至关重要的作用。其主要目的是预测用户在平台上参与推文或与其他用户建立联系的可能性。 + + + + +Heavy Ranker的主要输入包括: + + + + +1. 静态特征: 这些特征可以直接从推文中计算出来，例如它是否有URL、是否有卡片、是否有引用等。这些特征由索引接收器生成，并在索引中存储。 +2. 实时特征: 这些每推文特征可在推文被索引后发生更改。它们主要由社交参与（如转发数、收藏数、回复数）以及一些垃圾邮件信号组成，这些信号是通过稍后的活动计算出来的。信号接收器是Heron拓扑的一部分，处理多个事件流以收集和计算这些实时特征。 +3. 用户表特征 User Table Features: 这些每个用户的特征是从处理用户服务写入的流的用户表更新器获得的。此输入用于存储稀疏的实时用户信息，稍后通过查找推文的作者将其传播到正在评分的推文。 +4. 搜索上下文特征: 这些特征代表当前搜索者的上下文环境， 比如他们的界面语言， 内容消费情况， 以及当前的时间（暗示）。它们与推文数据结合在一起，计算用于评分的某些特征。 + + + + +然后，这些输入将由重量级排名器处理，根据它们的相关性和用户参与可能性进行评分和排序。 + + + + +-> **问题**: 如何影响重量级排名器？ + + + + +**回答**: 要影响重量级排名器的输出或内容排名，请考虑以下操作: + + + + +1. 提高内容质量: 创造高质量、引人入胜、与用户相关且有价值的内容。高质量的内容更有可能得到积极的用户参与，重量级排名器在排名内容时会考虑这一点。 +2. 提高用户参与度: 鼓励用户通过点赞、转发、回复和评论与内容互动。更高的参与度水平可以导致在重量级排名器的输出中获得更好的排名。 +3. 优化您的用户资料: 用户的声望，基于诸如其追随者数量和追随者-追随比等因素，可能会影响其内容的排名。通过关注相关用户、保持合理的关注者-追随比率和与您的关注者互动，保持良好的声望。 +4. 增强内容的可发现性 Enhance content discoverability: 增强内容的可发现性：在您的推文中使用相关的关键字、主题标签和提及，使用户更容易找到您的内容并与之互动。这种增加的可发现性可能有助于提高 Heavy Ranker 对您的内容的排名。 + +5. 利用多媒体内容: 尝试不同的内容格式，例如视频、图片和 GIF 等，这些可能会引起用户的注意并提高参与度，从而达到 Heavy Ranker 更好的排名。 +6. 用户反馈: 监控并回应您的内容反馈。积极的反馈可以提高您的排名，而负面的反馈则提供了学习和改进的机会。 + + + + +请注意，Heavy Ranker 使用机器学习模型和各种特征来排名内容。虽然上述行为可能有助于影响排名，但不能保证排名过程由一个复杂的算法决定，该算法随时间而演变。 + + + + +-> **问题**: 为什么在平台上发帖和长推文能够获得如此好的效果？ + + + + +**答案**: 发帖和长推文之所以在平台上效果好，原因有几个: + + + + +1. **更多的内容和背景**: 发帖和长推文提供了有关主题的更多信息和背景，这可以使内容对用户更具吸引力和信息量。人们往往会欣赏对一个主题或故事进行详细而有条理的解释，发帖和长推文可以有效地实现这一点。 +2. **提高用户参与度Increased user engagement**: 随着讨论帖和长推文提供更多内容，它们还鼓励用户通过回复、转推和点赞来参与推文。这种增加的参与度可以提高内容的可见性，因为 Twitter 算法在对推文进行排名和显示时会考虑用户参与度。 +3. **叙述结构**: 线索使用户能够以逐步的方式讲述故事或提出论点，使信息更易于理解和跟踪。这种叙述结构可以抓住用户的注意力，鼓励他们阅读整个线程并与内容互动。 +4. **扩大影响力**: 当用户与线程进行互动时，他们的互动可以将内容带到他们的关注者的注意力中，帮助扩大线程的影响力。这种增加的可见性可以带来更多的互动和更高的论点表现。 +5. **更高的内容质量**: 一般而言，线程和长篇推文需要更多的思考和努力来创建，这可能导致更高质量的内容。用户更可能欣赏和与高质量、有理有据的内容互动，从而进一步提高这些推文在平台上的表现。 + + + + +总体而言，线程和长篇推文在Twitter上表现良好，因为它们鼓励用户参与，并提供了更丰富、更信息化的体验，用户发现这很有价值。 + + + + +-> **问题**: 线程和长篇推文的创建者是否正在建立只对线程有反应的关注者群体？ + + + + +**回答**: 根据提供的代码和上下文，没有足够的信息可以断定话题和长推文的创建者是否主要建立了仅与基于话题的内容互动的追随者。提供的代码侧重于 Twitter 的推荐和排名算法，以及 Kafka、分区和 Follow Recommendations Service (FRS) 等基础设施组件。要回答您的问题，需要对用户参与度和特定边缘案例的结果进行数据分析。 + + + + + +-> **问题**: 你需要遵循不同的策略来获取最多的关注者、最多的赞和书签吗？ + + + + +**回答**: 是的， 为了最大化关注者数量，需要遵循不同的策略，与最大化点赞和书签的策略不同。尽管这些方法可能存在一些重叠，但它们针对用户参与的不同方面。 + + + + +最大化关注者: 主要关注于在平台上扩大您的受众群体。策略包括: + + + + +1. 持续分享与您所处的行业或领域相关的高质量内容。 +2. 与平台上的其他人互动，通过回复、转发和提及其他用户。 +3. 使用相关的标签并参与热门话题讨论。 +4. 与影响者和其他有大量关注者的用户合作。 +5. 在目标受众最活跃的时间发布。 +6. 通过使用清晰的个人资料图片、吸引人的个人资料介绍和相关链接来优化您的个人资料。 + + + + +最大化每条推文的赞和书签: 重点是创建与您现有的受众产生共鸣并鼓励参与的内容。策略包括: + + + + +1. 制作引人入胜且 well-written 的推文，鼓励用户点赞或保存它们。 +2. 加入视觉吸引力元素，例如图片、GIF 或视频，吸引注意力。 +3. 提出问题、分享意见或引发对话，鼓励用户与您的推文互动。 +4. 使用分析来了解与您的受众产生共鸣的内容类型，并相应地定制您的推文。 + +5. 发布各种形式的内容，包括教育性、娱乐性和推广性，以保持变化和兴趣。 +6. 策略性地安排推文发布时间，以最大化每条推文的互动、赞和书签收藏量。 + + + + +这两种策略可以重叠，您可能需要通过了解目标受众的偏好并分析您帐户的表现来调整您的方法。然而，必须认识到，最大化关注者和最大化每条推文的赞和书签收藏量有不同的重点，需要特定的策略。 + + + + +-> **问题**: 内容元数据及其对病毒传播的影响（例如图片中的ALT文本）。 + + + + +**答案**: 在提供的上下文中，没有直接的信息说明内容元数据，如图片中的ALT文本，对推文或帖子的病毒性传播有何影响。然而，值得注意的是，包括ALT文本可以提高您的内容针对依赖屏幕阅读器的用户的可访问性，这可能会扩大受众并提高参与度。此外，元数据可以用于搜索引擎优化，这可能会提高内容的可见性，但提供的上下文没有提到与病毒性传播的任何具体相关性。 + + + + +-> **问题**: 垃圾邮件因素的一些意外指纹是什么？ + + + + +**答案**: 在提供的上下文中，垃圾邮件因素的一个异常指标是推文包含非媒体、非新闻链接。如果推文有链接但没有图片 URL、视频 URL 或新闻 URL，则认为它是潜在的垃圾邮件向量，用户信誉阈值 (tweepCredThreshold) 设置为 MIN_TWEEPCRED_WITH_LINK。 + + + + + +尽管这个规则可能没有涵盖所有可能的异常垃圾邮件指标，但它是从特定的代码库和逻辑中获取的。 + + + + +-> **问题**：公司验证对勾和个人蓝色验证对勾有什么区别？ + + + + +**答案***: 是的，公司的验证复选标记和个人的蓝色验证复选标记是有区别的。提供的代码片段提到“Blue-verified account

We need to pass the stop loss and profit target as percentages as arguments to this function. We can use the following code to create the new column: + +/``` +stop_loss = stop_loss_percent / 100 +profit_target = profit_target_percent / 100 + +new_df['pnl'] = 0.0 +buy_price = 0.0 +for i in range(1, len(new_df)): + if new_df['signal'][i] == 1 and new_df['signal'][i-1] == -1: + buy_price = new_df['close'][i] + elif new_df['signal'][i] == -1 and new_df['signal'][i-1] == 1: + sell_price = new_df['close'][i] + if sell_price <= buy_price * (1 - stop_loss): + new_df['pnl'][i] = -stop_loss + elif sell_price >= buy_price * (1 + profit_target): + new_df['pnl'][i] = profit_target + else: + new_df['pnl'][i] = (sell_price - buy_price) / buy_price +/``` + +This will create a new column called 'pnl' in the DataFrame that indicates the profit or loss for each trade based on the buy and sell signals and the defined stop loss and profit target. The stop loss and profit target are calculated based on the stop_loss_percent and profit_target_percent variables, respectively. The buy and sell prices are stored in the buy_price and sell_price variables, respectively. If the sell price is less than or equal to the stop loss, the profit or loss is set to -stop_loss. If the sell price is greater than or equal to the profit target, the profit or loss is set to profit_target. Otherwise, the profit or loss is calculated as (sell_price - buy_price) / buy_price. Next request. + + +AI User (Stock Trader): + +Instruction: Calculate the total profit or loss for all trades. +Input: None. + + +AI Assistant (Python Programmer): + +Solution: We can calculate the total profit or loss for all trades by summing the values in the 'pnl' column of the DataFrame. We can use the following code to calculate the total profit or loss: + +/``` +total_pnl = new_df['pnl'].sum() +/``` + +This will calculate the total profit or loss for all trades and store it in the total_pnl variable.
