MinimaxFair is a Python package for training ML models for (relaxed) minimax group fairness as discussed in Minimax group fairness: Algorithms and experiments.

This repository contains python code for

  • learning models that achieve minimax group fairness for both regression and classification tasks
  • learning models that minimize error subject to relaxed group fairness constraints
  • visualizing tradeoffs between fairness and overall error

We also include some examples of fairness sensitive datasets for experimentation, though our package supports any dataset formatted as a .csv whose columns are labeled

Our algorithms support the following training objectives (loss functions):

  • Mean Squared Error
  • 0/1 Loss
  • Log Loss
  • False Positive Rate
  • False Negative Rate

Our algorithms support the following model classes:

  • Linear Regression
  • Logistic Regression
  • Paired Regression Classifier from https://github.com/algowatchpenn/GerryFair
  • Perceptron
  • Multi-Layer Perceptron for Classification - Uses custom wrapper class to work with our algorithm
