Linear unit-tests for invariance discovery - Code

Official code for the paper Linear unit-tests for invariance discovery, presented as a spotlight talk at the NeurIPS 2020 Workshop Causal Discovery & Causality-Inspired Machine Learning.

Installing requirements

conda create -n invariance python=3.8
conda activate invariance
python3.8 -m pip install -U -r requirements.txt

Running a single experiment

python3.8 scripts/main.py \
    --model ERM --dataset Example1 --n_envs 3 \
    --num_iterations 10000 --dim_inv 5 --dim_spu 5 \
    --hparams '{"lr":1e-3, "wd":1e-4}' --output_dir results/

Running the experiments and printing results

python3.8 scripts/sweep.py --num_iterations 10000 --num_data_seeds 1 --num_model_seed 1 --output_dir results/
python3.8 scripts/collect_results.py results/COMMIT

Reproducing the figures

bash reproduce_plots.sh

Reproducing the results (requires a cluster)
