Reinforcement Learning with Metacognitive Feedback Elicits Faithful Uncertainty Expression in LLMs
Evolving story · 1 updatesMetacognitive Advances in LLMsTimeline →Researchers propose using metacognitive feedback to improve uncertainty expression in large language models (LLMs). This approach aims to address systemic deficiencies in LLMs' metacognitive faculties.
Metacognition is a critical component of intelligence that describes the ability to monitor and regulate one's own cognitive processes. Yet LLMs exhibit systemic deficiencies in key metacognitive faculties: they hallucinate with high confidence, fail to recognize knowledge boundaries, and misrepresent their internal uncertainty--undermining trustworthiness and reliability. Since monitoring task performance and adapting behavior accordingly are central to metacognition, we posit that models capable of accurately judging their own performance are better positioned to improve it. We operationaliz
