Regularizes interpretations (computed via contextual decomposition) to improve neural networks. Official code for Interpretations are useful: penalizing explanations to align neural networks with prior knowledges (ICML 2020 pdf).
Note: this repo is actively maintained. For any questions please file an issue.
- fully-contained data/models/code for reproducing and experimenting with CDEP
- the src folder contains the core code for running and penalizing contextual decomposition
- in addition, we run experiments on 4 datasets, each of which are located in their own folders
- notebooks in these folders show demos for different kinds of text
ISIC skin-cancer classification - using CDEP, we can learn to avoid spurious patches present in the training set, improving test performance!
The segmentation maps of the patches can be downloaded here
ColorMNIST - penalizing the contributions of individual pixels allows us to teach a network to learn a digit's shape instead of its color, improving its test accuracy from 0.5% to 25.1%
Fixing text gender biases - CDEP can help to learn spurious biases in a dataset, such as gendered words
using CDEP requires two steps:
- run CD/ACD on your model. Specifically, 3 things must be altered:
- the pred_ims function must be replaced by a function you write using your own trained model. This function gets predictions from a model given a batch of examples.
- the model must be replaced with your model
- the current CD implementation doesn't always work for all types of networks. If you are getting an error inside of
cd.py, you may need to write a custom function that iterates through the layers of your network (for examples seecd.py)
- add CD scores to the loss function (see notebooks)
- ACD (ICLR 2019 pdf, github) - extends CD to CNNs / arbitrary DNNs, and aggregates explanations into a hierarchy
- PDR framework (PNAS 2019 pdf) - an overarching framewwork for guiding and framing interpretable machine learning
- TRIM (ICLR 2020 workshop pdf, github) - using simple reparameterizations, allows for calculating disentangled importances to transformations of the input (e.g. assigning importances to different frequencies)
- DAC (arXiv 2019 pdf, github) - finds disentangled interpretations for random forests
