XAI-Bench is a library for benchmarking feature attribution techniques using synthetic data. Unlike real-world datasets, synthetic datasets allow the efficient computation of conditional expected values that are needed to evaluate many explainability metrics such as ground-truth Shapley values, faithfulness, and monotonicity. This repository can be used to benchmark six different feature attribution techniques across five popular evaluation metrics.

See our NeurIPS Datasets Track paper at https://arxiv.org/abs/2106.12543.

Installation

To use our package, make sure you install all the dependencies in requirements.txt using

pip install -r requirements.txt

Sample Usage

We use an Experiment to benchmark various datasets, models, explainers, metrics. This is the recommended way to access our library.

To run a sample benchmarking experiment on our GaussianPiecewiseConstant dataset using the sample config configs/experiment_config.json, run

python main_driver.py --mode regression --seed 7 --experiment --experiment-json configs/experiment_config.jsonc --no-logs

For running several experiments across multiple datasets, use a script as shown in,

./script.sh

Each Experiment object is saved after execution for checkpointing. This way, additional experiments can be run without having to rerun previous computation.


More details

The API uses main_driver.py which takes in the arguments -

> python main_driver.py -h

usage: Driver for the explainability project [-h] [--mode {classification,regression}] --dataset DATASET --model MODEL --explainer
