Mosaic IT: Enhancing Instruction Tuning with Data Mosaics
This is the repo for the Mosaic-IT project, which introduces an augmentation method for Instruction Tuning, which concurrently improves the LLM performances and lowers the training expenses.
(Feel free to email minglii@umd.edu for any questions or feedback.)
- [2024/05] We initialized the Mosaic-IT repo.
Finetuning large language models with a variety of instruction-response pairs has enhanced their capability to understand and follow instructions. Current instruction tuning primarily relies on teacher models or human intervention to generate and refine the instructions and responses, which are costly, non-sustainable, and may lack diversity. In this paper, we introduce Mosaic Instruction Tuning (Mosaic-IT), a human/model-free method that can efficiently create rich and diverse augmentations from existing instruction tuning data to enhance the finetuned LLM. Mosaic-IT randomly concatenates multiple instruction data into one and trains the model to produce the corresponding responses with predefined higher-level meta-instructions to strengthen its multi-step instruction-following and format-following skills. Our extensive evaluations demonstrate a superior performance and training efficiency of Mosaic-IT, which achieves consistent performance improvements over various benchmarks and an 80% reduction in training costs compared with original instruction tuning.
Illustration of Mosaic-IT. The upper section represents the original Instruction Tuning method. In the middle is our method with the Primary Mosaic strategy, which concatenates instructions and corresponding responses as an augmentation for better Instruction Tuning. On the right are corresponding data examples of each method. The lower section illustrates the three Auxiliary Mosaic Strategies for Mosaic-IT.
- We extend the instruction tuning process into arbitrarily following multiple instructions, rather than one instruction at a time, which dramatically digs out the potential of the existing instruction tuning dataset.
- Our Mosaic-IT (1) achieves better performances on various benchmarks, with (2) 80% reduction on training cost (3) without using any extra models。
- Our method is a potential attempt to alleviate the memorizing effects during training, see Further Discussion for details.
- The Mosaic Strategies and Predefined Rules in our method can be easily further extended, potentially further improve the Mosaic-IT performance.
Install the dependencies with pip install -r requirements.txt
Note: The use of Mosaic-IT only needs the transformers package, thus if you are using a different code base with transformers installed, you can directly run the code and manually install the missing packages.
