Talk Title
Robustness Issues in Counterfactual Explanations for Deep Learning Models.
Abstract
Counterfactual explanations (CEs) are advocated as being ideally suited to providing algorithmic recourse for subjects affected by the predictions of machine learning models. While CEs can be beneficial to affected individuals, recent work has exposed severe issues related to the robustness of state-of-the-art methods for obtaining CEs. Since a lack of robustness may compromise the validity of CEs, techniques to mitigate this risk are in order. In this talk we will begin by introducing the problem of (lack of) robustness and discuss its implications on fairness. We will then present some recent solutions we developed to compute CXs with robustness guarantees.
