A new method called CORD (Calibrator-Output Repair for Top-1 Decision Preservation) has been developed to address the issue of post-hoc calibration in machine learning models. Unlike previous methods that could alter the top-1 prediction, CORD ensures the original prediction remains unchanged while still correcting the confidence scores. This is achieved by repairing the calibrated probability vector to preserve the initial top-1 decision. Experiments on datasets like CIFAR-10/100 and ImageNet-1K show that CORD successfully maintains zero Top-1 Prediction Change Rate (TPCR) and improves metrics such as Expected Calibration Error (ECE) and Negative Log-Likelihood (NLL).
