LLM uncertainty quantification research explores calibration for reliable answers

By PulseAugur Editorial · [2 sources] ·

Two research papers explore methods for improving the reliability of answers generated by large language models (LLMs), particularly in question-answering tasks. The first paper introduces A-CRC-QA, a post-hoc calibration framework designed to control error rates among accepted answers by reformulating selection-conditioned error control as a linear expectation constraint. The second paper empirically studies how to derive calibrated confidence estimates from token probabilities for mathematical question answering, comparing single-pass and multi-pass estimators and evaluating post-hoc calibration methods like Platt scaling and isotonic regression.
