New method CreDRO captures epistemic uncertainty beyond training randomness

Researchers have introduced CreDRO, a novel method for learning credal ensembles that better captures epistemic uncertainty. Unlike previous approaches that primarily attributed uncertainty to optimization randomness, CreDRO defines it as disagreement among models trained with variations of the i.i.d. assumption. This allows CreDRO to account for uncertainty arising from potential distribution shifts between training and test data. Empirical results demonstrate CreDRO's superior performance over existing credal methods in out-of-distribution detection and selective classification tasks. AI

IMPACT This new method for capturing epistemic uncertainty could lead to more robust AI systems, particularly in applications sensitive to distribution shifts.
