Researchers have introduced Pandora's Regret, a novel scoring rule designed to evaluate sequential search processes more effectively than traditional methods. Unlike local rules like log loss, Pandora's Regret considers the ranking of alternatives and the costs associated with testing them. This new rule is derived from analyzing expected search costs and provides a way to elicit true probabilities while penalizing miscalibrations that rank incorrect options higher than the correct one. Its application to MedMNIST models demonstrated a better prediction of clinical diagnostic costs compared to existing metrics. AI
