Provably Robust and Plausible Counterfactual Explanations for Neural Networks via Robust Optimisation

1 code implementation22 Sep 2023 Junqi Jiang, Jianglin Lan, Francesco Leofante, Antonio Rago, Francesca Toni

In this work, we propose Provably RObust and PLAusible Counterfactual Explanations (PROPLACE), a method leveraging on robust optimisation techniques to address the aforementioned limitations in the literature.

Formalising the Robustness of Counterfactual Explanations for Neural Networks

1 code implementation31 Aug 2022 Junqi Jiang, Francesco Leofante, Antonio Rago, Francesca Toni

Existing attempts towards solving this problem are heuristic, and the robustness to model changes of the resulting CFXs is evaluated with only a small number of retrained models, failing to provide exhaustive guarantees.
