DiffMask

Overview

This library contains a Pytorch implementation of Differentiable Masking Explainer (Diffmask), as presented in [1](https://arxiv.org/abs/2004.14992).

Dependencies

• python>=3.6
• pytorch>=1.5: https://pytorch.org
• pytorch-lightning==0.7.3: https://pytorch-lightning.readthedocs.io
• transformers>=2.9.0: https://github.com/huggingface/transformers
• torch-optimizer>=0.0.1a9: https://github.com/jettify/pytorch-optimizer
• matplotlib>=3.1.1: https://matplotlib.org

Notice that older or newer version could work but they were not tested.

Installation

To install, run

$ python setup.py install

To donwload datasets run

$ ./scripts/download_datasets.sh

To download models, use the following link. Note that these are not the exact same models used for the paper.

Structure

• diffmask: Contains the source code for DiffMask.

We have 5 jupyter notebbok with the code for reproducing some of the results from our work [1]. Note that since i) the code was refactored and ii) we were not able to realise the exact same models used for the paper, re-generated plots and tables might differ from the ones in our work.

• QuestionAnsweringSquadAnalysis Plots and analysis using other methods of a BERT large model for question answering.
• QuestionAnsweringSquadDiffMaskAnalysis Plots and analysis using DiffMask of a BERT large model for question answering.
• SentimentClassificationSSTAnalysis Plots and analysis using other methods of a BERT base model for sentiment analisys.
• SentimentClassificationSSTDiffMaskAnalysis Plots and analysis using DiffMask of a BERT base model for sentiment analisys.
• ToyTask Training, analysis and plots for the artificial toy task using both other methods and DiffMask.
