Calibration Methods and Transfer for UCBD Uncertainty Scores

Develop and evaluate calibration techniques for UCBD-derived uncertainty scores—including isotonic regression, temperature scaling, and cross-dataset calibration transfer—and determine their effectiveness and transferability beyond Platt scaling.

Background

While Platt scaling substantially improved calibration (ECE reduction by 88%) in the reported experiments, the authors did not investigate other standard calibration techniques or their transferability across datasets.

Explicitly noting that these options are not yet explored indicates an unresolved methodological question about achieving robust and transferable calibration for uncertainty estimates in this setting.
