abstract: Token probabilities—though individually overconfident—can yield informative confidence signals when aggregated across full answer sequences. Multi-pass methods (self-verification, Monte Carlo Dropout) achieve better calibration than single-pass baselines. Post-hoc calibration (Platt scaling, isotonic regression) reduces in-domain error but shows limited cross-dataset and cross-model transferability.

    text: Aggregating token probabilities over the full sequence captures small but consistent differences between correct and incorrect generations, yielding more informative confidence estimates.
    appearance: While individual token probabilities can be highly saturated, we find that aggregating token probabilities over the full sequence captures small but consistent differences between correct and incorrect generations, yielding more informative confidence estimates.
