Approximation of group explainers with coalition structure using Monte Carlo sampling on the product space of coalitions and features

no code implementations17 Mar 2023 Konstandinos Kotsiopoulos, Alexey Miroshnikov, Khashayar Filom, Arjun Ravi Kannan

In our work, we focus on a wide class of linear game values, as well as coalitional values, for the marginal game based on a given ML model and predictor vector.

On marginal feature attributions of tree-based models

1 code implementation16 Feb 2023 Khashayar Filom, Alexey Miroshnikov, Konstandinos Kotsiopoulos, Arjun Ravi Kannan

We exploit the symmetry to derive an explicit formula, with improved complexity and only in terms of the internal model parameters, for marginal Shapley (and Banzhaf and Owen) values of CatBoost models.

Model-agnostic bias mitigation methods with regressor distribution control for Wasserstein-based fairness metrics

no code implementations19 Nov 2021 Alexey Miroshnikov, Konstandinos Kotsiopoulos, Ryan Franks, Arjun Ravi Kannan

The post-processing methodology involves reshaping the predictor distributions by balancing the positive and negative bias explanations and allows for the regressor bias to decrease.

Stability theory of game-theoretic group feature explanations for machine learning models

no code implementations22 Feb 2021 Alexey Miroshnikov, Konstandinos Kotsiopoulos, Arjun Ravi Kannan

The first part of our work formulates a stability theory for these explanation operators by establishing certain bounds for both marginal and conditional explanations.

Wasserstein-based fairness interpretability framework for machine learning models

no code implementations6 Nov 2020 Alexey Miroshnikov, Konstandinos Kotsiopoulos, Ryan Franks, Arjun Ravi Kannan

The objective of this article is to introduce a fairness interpretability framework for measuring and explaining the bias in classification and regression models at the level of a distribution.
