Requires conda with Python 3.7.

1. Install conda dependencies in the environment: conda env create -f environment.yml
2. Run download_uci_data.sh from the repo main directory to download the Covertype dataset.
3. Activate the conda enviroment with conda activate robust_weighting
4. Setup up a wandb account and create a project named extreme-classification (or rename the project argument inside the wandb.init call inside src/main.py )

Navigate to the root of the repo.

Run ./power_exp.sh for the synthetic experiment results.

Run ./uci_exp.sh for the real world dataset (Covertype) results.
