Reproducing paper results

Sythetic data

To produce results

cd InvariantRiskMinimization/code/experiment_synthetic/
./run_sems.sh

To analyze results

noteooks/sem_results.ipynb

Color MNIST

To produce results

./exps/cmnist_label_noise_sweep.sh

To analyze results

notebooks/plot_cmnist_label_noise_sweep.ipynb

As an alternative, InvariantRiskMinimization/code/colored_mnist/optimize_envs.sh also runs EIIL+IRM on CMNIST with 25% label noise (the default from the IRM paper).
