CORD Ensures Post-hoc Calibration Preserves Original Top-1 Predictions
September 1, 2026
CORD is a post-fit adapter designed to correct confidence without altering the model's top-1 prediction. It repairs the calibrated probability vector by redistributing mass such that the original argmax remains unchanged, addressing the Top-1 Prediction Change Rate issue.
