CEL: Comprehensive Counterfactual Explanations Library and Benchmark

Oleksii Furman, Łukasz Lenkiewicz, Marcel Musiałek +1

Counterfactual explanations are a prominent approach in explainable artificial intelligence (xAI), providing actionable guidance on what input changes would alter a model's predict…

Counterfactual Explanations Under Concept Drift

Marcin Kostrzewa, Jerzy Stefanowski, Maciej Zięba

Counterfactual explanations (CFEs) provide actionable recourse, but most methods assume a static framework with fixed data and a trained classifier. This assumption breaks in evolv…

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

Oleksii Furman, Patryk Wielopolski, Łukasz Lenkiewicz +2

The growing complexity of AI systems has intensified the need for transparency through Explainable AI (XAI). Counterfactual explanations (CFs) offer actionable "what-if" scenarios…

A Probabilistic Consensus-Driven Approach for Robust Counterfactual Explanations

Marcin Kostrzewa, Maciej Zięba, Jerzy Stefanowski

Counterfactual explanations (CFEs) are essential for interpreting black-box models, yet they often become invalid when models are slightly changed. Existing methods for generating…

Towards plausibility in time series counterfactual explanations

Marcin Kostrzewa, Krzysztof Galus, Maciej Zięba

We present a new method for generating plausible counterfactual explanations for time series classification problems. The approach performs gradient-based optimization directly in…
