Unifying Perspectives: Plausible Counterfactual Explanations on Global, Group-wise, and Local Levels

no code implementations27 May 2024 Patryk Wielopolski, Oleksii Furman, Jerzy Stefanowski, Maciej Zięba

By offering a cohesive solution to the optimization and plausibility challenges in GCEs, our work significantly advances the interpretability and accountability of AI models, marking a step forward in the pursuit of transparent AI.

Probabilistically Plausible Counterfactual Explanations with Normalizing Flows

no code implementations27 May 2024 Patryk Wielopolski, Oleksii Furman, Jerzy Stefanowski, Maciej Zięba

PPCEF advances beyond existing methods by combining a probabilistic formulation that leverages the data distribution with the optimization of plausibility within a unified framework.

Multi-criteria approach for selecting an explanation from the set of counterfactuals produced by an ensemble of explainers

1 code implementation20 Mar 2024 Ignacy Stępka, Mateusz Lango, Jerzy Stefanowski

Counterfactuals are widely used to explain ML model predictions by providing alternative scenarios for obtaining the more desired predictions.
