FairPy Documentation

FairPy is a comprehensive Python Library for Machine Learning Fairness, covering various fairness notions, data structures, and learning tasks. TODO: This challenging field has many key Applications….

FairPy includes more than 10 latest fairness algorithms, such as InflFair (ICML’22) [LL22] and FairGLM (ICML’22) [DPM+22]. For consistency and accessibility, FairPy is developed on top of scikit-learn and PyTorch.

Sample Code of FairPy

from fairpy.dataset import Adult
from fairpy.model import LabelBias

model = LabelBias()     # Choose a fairness algorithm
dataset = Adult()       # Choose or customize a dataset
X, y, s = dataset.get_X_y_s()   # Extract features, labels, and sensitive attributes from the dataset

model.fit(X, y, s)      # Fit model with provided data
pred = model.predict(X) # Predict
