Recourse under Model Multiplicity via Argumentative Ensembling (Technical Report)

1 code implementation22 Dec 2023 Junqi Jiang, Antonio Rago, Francesco Leofante, Francesca Toni

Model Multiplicity (MM) arises when multiple, equally performing machine learning models can be trained to solve the same prediction task.

Promoting Counterfactual Robustness through Diversity

1 code implementation11 Dec 2023 Francesco Leofante, Nico Potyka

Counterfactual explanations shed light on the decisions of black-box models by explaining how an input can be altered to obtain a favourable decision from the model (e. g., when a loan application has been rejected).

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.
