TRACE: Single-Pass Decoding-Trace Risk Localization for Generation Calibration
TRACE is proposed, a single-pass, decoded-answer-preserving confidence estimator that treats decoding-time uncertainty as a trajectory through three steps: recording token-level surprisal and predictive entropy during decoding, applying local risk operators to preserve uncertainty spikes, and converting localized trace...
