This repo contains the refactored code and pointers to the data accompanying our paper "Efficient Explanations from Empirical Explainers".
Below, please find (1) pointers to the heatmaps promised in the paper, (2) instructions on how to replicate our experiments and (3) all our data, models and logs.
Disclaimer: This is a refactored and prettified version of the code and has not been tested exhaustively yet. This disclaimer will be removed when the tests have been conducted.
Here are the explanations and experiments.
Explanations are contained in the folder explanations
. Explanations are the attribution maps returned by the expensive target explainers and the Empirical Explainers. Each line contains an HTML document. Your browser probably will not be able to load all data at once. You can extract individual lines into separate files to solve that issue.
Our experiments (data, models, logs) can be downloaded from the folder experiments
or replicated as described below. Please note that the archives in experiments
range in size from 1 - 10 GB.
You can replicate our experimental results, following the steps below or download our data, model and logs, following the links at the bottom. Our experiments are config-driven.
We assume a base directory for all experiments with 5 sub folders:
- |-
data
: The raw data is downloaded here, using Huggingface's (HF) datasets. - |-
models
: Model parameters are saved here. - |-
explanations
: Saliency maps are saved here as json lines. - |-
visualizations
: We save attribution maps in html format here. - |-
logs
: Training, explanation and visualization logs are saved here.
- Install pytorch / torchvision
- Install the requirements listed in
requirements.txt
- A complete list of the exact requirements is contained in
pip.freeze.txt
- A complete list of the exact requirements is contained in
All jobs are coordinated using the flags and pointers in ./configs/run_job.jsonnet
.
To run a job, adapt the config and then run, e.g.
CUDA_VISIBLE_DEVICES=0 python run_job.py 2>&1 | tee -a <base-dir>/logs/job.log
In run_job.jsonnet
, please set the download
flag to true
and let path_config_download
point to a download configuration file. Example files are provided in
./configs/snli/download/
and ./configs/imdb/download/
. We annotated
./configs/imdb/download/download.imdb.validation.jsonnet
We save the training data to |-data/train/
, the validation data to |-data/validation/
and the test data to |data/test/
.
We train models using PyTorch Ignite in conjunction w/ HF's Transformers.
The training is again config-driven. We annotated the fields in
./configs/imdb/train/train.downstream.jsonnet
.
After training, the model can be found in |-models
.
We explain models using PyTorch's Captum. The training is again config driven, an annotated config is provided in
./configs/imdb/explain/explain.expensive.jsonnet
Explanations are written to json lines. The json file can be found in |-explanations/
, after the job is done.
At a minimum, an explanation contains the fields input_ids
and attributions
.
The training of the Empirical Explainer uses the same script as the training of the downstream model. An annotated config file is provided in
./configs/train/train.empirical-explainer.jsonnet
The model weights can be found in |-models/
after training.
The efficient explanations are generated with the same script as the expensive explanations. An annotated config file is provided in
./configs/imdb/explain/explain.empirical.jsonnet
Explanations are written to json lines again, which can be found in |-explanations
after the job is done.
Evaluation statistics are logged, which requires you to pipe the logger output into a log, e.g. using
2>&1 | tee -a <base-dir>/logs/my-log.log
An example config file is provided
./configs/imdb/evaluate/evaluate.jsonnet
The MSEs between the specified target explanations and the approximative explanations are logged, as is the weighted F1 score, which is derived from the true labels and predictions that should be contained in the expensive target explanations.
Finally, you can visualize explanations. For this, specify one or many explanations to load. It is assumed that the instances contained in the json lines appear in the same order in the files you specified.
We again provide an annotated config file
./configs/visualize/visualize.jsonnet
After the job is done, the sub folder |-visualizations/
contains the heatmaps. The heatmaps are written to a file,
line by line, where each line is an HTML document that contains the explanations.
