Fair regression under localized demographic parity constraints

Arthur Charpentier, Christophe Denis, Romuald Elie +2

Demographic parity (DP) is a widely used group fairness criterion requiring predictive distributions to be invariant across sensitive groups. While natural in classification, full…

Federated Measurement of Demographic Disparities from Quantile Sketches

Arthur Charpentier, Agathe Fernandes Machado, Olivier Côté +1

Many fairness goals are defined at a population level that misaligns with siloed data collection, which remains unsharable due to privacy regulations. Horizontal federated learning…

Decomposing Direct and Indirect Biases in Linear Models under Demographic Parity Constraint

Bertille Tierny, Arthur Charpentier, François Hu

Linear models are widely used in high-stakes decision-making due to their simplicity and interpretability. Yet when fairness constraints such as demographic parity are introduced,…

EquiPy: Sequential Fairness using Optimal Transport in Python

Agathe Fernandes Machado, Suzie Grondin, Philipp Ratz +2

Algorithmic fairness has received considerable attention due to the failures of various predictive AI systems that have been found to be unfairly biased against subgroups of the po…

From Uncertainty to Precision: Enhancing Binary Classifier Performance through Calibration

Agathe Fernandes Machado, Arthur Charpentier, Emmanuel Flachaire +2

The assessment of binary classifier performance traditionally centers on discriminative ability using metrics, such as accuracy. However, these metrics often disregard the model's…

A Sequentially Fair Mechanism for Multiple Sensitive Attributes

François Hu, Philipp Ratz, Arthur Charpentier

In the standard use case of Algorithmic Fairness, the goal is to eliminate the relationship between a sensitive variable and a corresponding score. Throughout recent years, the sci…
