Understanding Interventional TreeSHAP : How and Why it Works

1 code implementation29 Sep 2022 Gabriel Laberge, Yann Pequignot

Shapley values are ubiquitous in interpretable Machine Learning due to their strong theoretical background and efficient implementation in the SHAP library.

Partial Order in Chaos: Consensus on Feature Attributions in the Rashomon Set

1 code implementation26 Oct 2021 Gabriel Laberge, Yann Pequignot, Alexandre Mathieu, Foutse khomh, Mario Marchand

In this work, instead of aiming at reducing the under-specification of model explanations, we fully embrace it and extract logical statements about feature attributions that are consistent across all models with good empirical performance (i. e. all models in the Rashomon Set).

Out-of-distribution detection for regression tasks: parameter versus predictor entropy

no code implementations24 Oct 2020 Yann Pequignot, Mathieu Alain, Patrick Dallaire, Alireza Yeganehparast, Pascal Germain, Josée Desharnais, François Laviolette

Focusing on regression tasks, we choose a simple yet insightful model for this OOD distribution and conduct an empirical evaluation of the ability of various methods to discriminate OOD samples from the data.

Embeddability on functions: order and chaos

no code implementations22 Feb 2018 Raphaël Carroy, Yann Pequignot, Zoltán Vidnyánszky

Our main result is the following dichotomy: the embeddability quasi-order restricted to continuous functions from a given compact space to another is either an analytic complete quasi-order or a well-quasi-order.
