Feature Release

qlik-py-tools-8.0.zip

This zip archive only contains the files needed to deploy the SSE. You can get sample Qlik Sense apps from the docs or download the full source code below.

Tips for updating on Windows
You'll need to download the zip file above, extract it and run Qilk-Py-Init as an administrator. Any model's trained previously will need to be re-trained.

Change Log v.8.0

  • Ability to call pre-trained models that provide a REST API from the load script and chart expressions.
  • Removed dependency on skater. Upgraded to scikit-learn 0.23.1 which now provides the capability to calculate feature importances.
  • Updated HDBSCAN to version 0.8.26
  • Updated spaCy to version 2.2.4
  • Docker image v.8.0 released.

Change Log v.7.0

  • Ability to call externally trained scikit-learn and Keras models for predictions.
  • Sample app and documentation added here.
  • Additional sample app for forecasting with scikit-learn using existing capabilities.

Recent Updates

This release adds the capability to use pre-trained scikit-learn, Keras and REST API based models with Qlik. Read more here.

With version 6, Deep Learning capabilities were added through integration with Keras and Tensorflow. This offers powerful capabilities for sequence predictions and complex timeseries forecasting.

PyTools now also includes the ability to use Additional Regressors with Prophet, allowing you to model more complex timeseries.

For more information refer to the Usage section.

Capabilities

  • Supervised Machine Learning : Implemented using scikit-learn, the go-to machine learning library for Python. This SSE implements the full machine learning flow from data preparation, model training and evaluation, to making predictions in Qlik.
  • Unsupervised Machine Learning : Also implemented using scikit-learn. This provides capabilities for dimensionality reduction and clustering.
  • Deep Learning : Implemented using Keras and TensorFlow. This SSE implements the full flow of setting up a neural network, training and evaluating it, and using it to make predictions. Deep Learning models can be used for sequence predictions and complex timeseries forecasting.
  • Use of pretrained ML models in Qlik : Pre-trained scikit-learn, Keras and REST API based models can be called from this SSE, allowing predictions to be exposed within the broader analysis and business context of a Qlik app. The implementation also allows for What-if analysis using the models.
  • Named Entity Recognition : Implemented using spaCy, an excellent Natural Language Processing library that comes with pre-trained neural networks. This SSE allows you to use spaCy's models for Named Entity Recognition or retrain them with your data for even better results.
  • Association rules : Implemented using Efficient-Apriori. Association Rules Analysis is a data mining technique to uncover how items are associated to each other. This technique is best known for Market Basket Analysis, but can be used more generally for finding interesting associations between sets of items that occur together, for example, in a transaction, a paragraph, or a diagnosis.
  • Clustering : Implemented using HDBSCAN, a high performance algorithm that is great for exploratory data analysis.
  • Time series forecasting : Implemented using Facebook Prophet, a modern library for easily generating good quality forecasts. Now with the ability to use multiple regressors as input.
  • Seasonality and holiday analysis : Also using Facebook Prophet.
  • Linear correlations : Implemented using Pandas.
