New framework CoCHI targets internal LLM components to fix overconfident errors

A new framework called CoCHI has been developed to address overconfident errors in large language models (LLMs). Unlike existing methods that adjust outputs or retrain models, CoCHI intervenes in the LLM's internal components that are responsible for distinct confidence behaviors. By analyzing correctness-confidence patterns, CoCHI targets specific internal structures to reduce incorrect high-confidence predictions while preserving accurate ones. Experiments show that CoCHI consistently improves calibration metrics like Expected Calibration Error and Brier Score across various LLMs, offering a more mechanistic approach to model reliability.
