To Pool or Not To Pool: Analyzing the Regularizing Effects of Group-Fair Training on Shared Models

AISTATS 2024poster

In fair machine learning, one source of performance disparities between groups is overfitting to groups with relatively few training samples. We derive group-specific bounds on the generalization error of welfare-centric fair machine learning that benefit from the larger sample size of the majority…

Shapley Residuals: Quantifying the limits of the Shapley value for explanations

NeurIPS 2021poster

Popular feature importance techniques compute additive approximations to nonlinear models by first defining a cooperative game describing the value of different subsets of the model's features, then calculating the resulting game's Shapley values to attribute credit additively between the features.…

Problems with Shapley-value-based explanations as feature importance measures

ICML 2020poster

Game-theoretic formulations of feature importance have become popular as a way to "explain" machine learning models. These methods define a cooperative game between the features of a model and distribute influence among these input elements using some form of the game’s unique Shapley values. Justif…
