Researchers have introduced a new metric called epistemic calibration to evaluate the trustworthiness of uncertainty estimates in machine learning models, particularly for second-order classification tasks. This metric goes beyond classical calibration by assessing whether the reported epistemic uncertainty accurately reflects the dispersion of model predictions against the ground truth. The proposed Expected Epistemic Calibration Error (EECE) serves as a consistent estimator for this new criterion, and experiments demonstrate its effectiveness in revealing significant differences in uncertainty quantification methods.
