Training Fair Tabular Foundation Models

Patrik Kenfack, Jesse C. Cresswell, Anthony L. Caterini +2

Tabular Foundation Models (TFMs) have emerged as leading methods for tabular predictive tasks, leveraging in-context learning to predict on new data without task-specific training.…

Model Stealing Through the Lens of Model Multiplicity

Eliott Baltz, Satoshi Hara, Ulrich Aïvodji

Model stealing attacks, where adversaries create high-fidelity surrogate models, are a significant threat to the intellectual property of machine learning services. Conventional wi…

When Interpretability Is Unequally Distributed: Fairness in Hybrid Interpretable Models

Ziba Jabbar Zare, Ulrich Aïvodji, Julien Ferry +1

Hybrid interpretable models combine a transparent component with a black-box model by assigning some examples to the former and deferring the rest to the latter. While this design…

Test-Time Collective Action: Proxy-Based Perturbations for Correcting Algorithmic Harms

Meghana Bhange, Ulrich Aïvodji, Elliot Creager

When machine learning systems under-perform for particular subgroups, affected users typically have no way to correct these disparities without relying on platform-level fixes. Exi…
