Decomposing Probabilistic Scores: Reliability, Information Loss and Uncertainty

Arthur Charpentier, Agathe Fernandes Machado

Calibration is a conditional property that depends on the information retained by a predictor. We develop decomposition identities for arbitrary proper losses that make this depend…

Sequential Transport for Causal Mediation Analysis

Agathe Fernandes Machado, Iryna Voitsitska, Arthur Charpentier +1

We propose sequential transport (ST), a distributional framework for mediation analysis that combines optimal transport (OT) with a mediator directed acyclic graph (DAG). Instead o…

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…

Beyond Shapley Values: Cooperative Games for the Interpretation of Machine Learning Models

Marouane Il Idrissi, Agathe Fernandes Machado, Arthur Charpentier

Cooperative game theory has become a cornerstone of post-hoc interpretability in machine learning, largely through the use of Shapley values. Yet, despite their widespread adoption…

Unveil Sources of Uncertainty: Feature Contribution to Conformal Prediction Intervals

Marouane Il Idrissi, Agathe Fernandes Machado, Ewen Gallic +1

Cooperative game theory methods, notably Shapley values, have significantly enhanced machine learning (ML) interpretability. However, existing explainable AI (XAI) frameworks mainl…

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…
