Explaining Concept Drift through the Evolution of Group Counterfactuals

Ignacy Stępka, Jerzy Stefanowski

Machine learning models in dynamic environments often suffer from concept drift, where changes in the data distribution degrade performance. While detecting this drift is a well-st…

The Problem of Coherence in Natural Language Explanations of Recommendations

Jakub Raczyński, Mateusz Lango, Jerzy Stefanowski

Providing natural language explanations for recommendations is particularly useful from the perspective of a non-expert user. Although several methods for providing such explanatio…

Counterfactual Explanations with Probabilistic Guarantees on their Robustness to Model Change

Ignacy Stępka, Mateusz Lango, Jerzy Stefanowski

Counterfactual explanations (CFEs) guide users on how to adjust inputs to machine learning models to achieve desired outputs. While existing research primarily addresses static sce…

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

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. They can be generated by a variety of…
