Second Guess: Detecting Uncertainty Through Abstention and Answer Stability in Small Language Models 事件

Second Guess: Detecting Uncertainty Through Abstention and Answer Stability in Small Language Models arXiv:2605.25394v1 Announce Type: cross Abstract: Large language models often generate confident but incorrect answers rather than abstaining when uncertain. This problem is particularly acute for small language models (SLMs), where computational constraints and autonomous operation amplify the need for reliable uncertainty detection. We propose _Second Guess_, a lightweight, parameter-free prom
