Learning Invariant Graph Representations Through Redundant Information

Barproda Halder, Pasan Dissanayake, Sanghamitra Dutta

Learning invariant graph representations for out-of-distribution (OOD) generalization remains challenging because the learned representations often retain spurious components. To a…

Counterfactual Explanations for Model Ensembles Using Entropic Risk Measures

Erfaun Noorani, Pasan Dissanayake, Faisal Hamman +1

Counterfactual explanations indicate the smallest change in input that can translate to a different outcome for a machine learning model. Counterfactuals have generated immense int…

Private Counterfactual Retrieval With Immutable Features

Shreya Meel, Pasan Dissanayake, Mohamed Nomeir +2

In a classification task, counterfactual explanations provide the minimum change needed for an input to be classified into a favorable class. We consider the problem of privately r…
