aequitas-fairlib 2.8.2

A library for detecting and mitigating bias in machine learning models, with a focus on interoperability with scikit-learn, Pandas, and PyTorch.

FairLib - Python Library for Fairness Metrics and Processing

This library provides a set of tools for measuring and improving fairness in machine learning models, covering a variety of fairness metrics, pre-processing, in-processing, and post-processing techniques.

Library functionality

The library will provide some fairness metrics to perform various analyses. Plus a number of pre-processing, in-processing and post-processing algorithms.

Fairness Metrics

• Statistical Parity Difference - Example Notebook
• Disparate Impact - Example Notebook
• Equal Opportunity Difference - Example Notebook

Pre-Processing Techniques

• Disparate Impact Remover - Example Notebook
• LFR (Learning Fair Representations) - Example Notebook
• Reweighing - Example Notebook

In-Processing Techniques

• FaUCI - Example Notebook
• Adversarial Debiasing - Example Notebook
• Prejudice Remover - Example Notebook

Restore dev dependencies

1. Install Poetry if you don't have it yet

pip install -r requirements.txt

2. Install the project's dependencies

poetry install

Run unit tests

poetry run poe test

Tests are automatically run in CI, on all pushes on all branches. There, tests are executed on multiple OS (Win, Mac, Ubuntu) and on multiple Python versions.
