Researchers have developed a new method called Reinforcement Learning with Metacognitive Feedback (RLMF) to improve how Large Language Models (LLMs) express their uncertainty. This approach uses the model's self-assessment of its performance to refine its responses and identify valuable training data, outperforming standard active learning techniques. Experiments demonstrate that RLMF significantly enhances Faithful Calibration, aligning expressed uncertainty with intrinsic confidence, and improves the LLMs' ability to recognize and communicate their knowledge boundaries.
