  NeurIPS (Conference on Neural Information Processing Systems) 2022

This is the code implementation for the NeurIPS 2022 paper above. Code and environments are adapted from the original Google ML-fairness-gym repo.

Installation

First, install Anaconda to set up virtual environment. Then, run:

conda create -n pocar python=3.8
conda activate pocar
pip install -r requirements.txt

Usage

First, cd to an experiment directory. Then, to train:

python main.py --train

To view training progress:

python main.py --show_train_progress

To evaluate models (make sure to specify model paths to evaluate in config.py):

python main.py --eval_path ./path/to/evaluations/

To view model evaluations:

python main.py --display_eval_path ./path/to/evaluations/

Environments

Attention Allocation

Lending

Vaccination / Infectious Disease Control
