Do Counterfactually Fair Image Classifiers Satisfy Group Fairness? -- A Theoretical and Empirical Study

Sangwon Jung, Sumin Yu, Sanghyuk Chun, Taesup Moon

The notion of algorithmic fairness has been actively explored from various aspects of fairness, such as counterfactual fairness (CF) and group fairness (GF). However, the exact relationship between CF and GF remains to be unclear, especially in image classification tasks; the rea…

CoMet: Context and Multiplicity Decomposition for Multimodal Uncertainty Estimation

Sanghyuk Chun, William Yang, Amaya Dharmasiri, Olga Russakovsky

Uncertainty estimation has been a long-standing challenge in AI models; it amounts to "knowing what you don't know," and metacognition is notoriously difficult even for humans (cf. the Dunning-Kruger effect). Although it is still far from solved even in simpler classification sys…
