DECAF (DEbiasing CAusal Fairness)

Code Author: Trent Kyono and Boris van Breugel

This repository contains the code used for the "DECAF: Generating Fair Synthetic Data Using Causally-Aware Generative Networks" paper(2021).

Installation

pip install -r requirements.txt
pip install .

Tests

You can run the tests using

pip install -r requirements_dev.txt
pip install .
pytest -vsx

Contents

• decaf/DECAF.py - Synthetic data generator class - DECAF.
• tests/run_example.py - Runs a nonlinear toy DAG example. The dag structure is stored in the dag_seed variable. The edge removal is stored in the bias_dict variable. See example usage in this file.

Examples

Base example on toy dag:

$ cd tests
$ python run_example.py

An example to run with a dataset size of 2000 for 300 epochs:

$ python run_example.py --datasize 2000 --epochs 300
