Uncertainty estimation is a critical technique used to improve the reliability of Large Language Models by mitigating hallucinations [1], [2], [3] and addressing overconfidence [4], [5]. It is specifically applied to these models through methods like probabilistic modeling and confidence-aware training [6], and is essential for safe deployment in sensitive domains like clinical decision-making [7], [8].

claimIn clinical settings, Large Language Models (LLMs) require robust mechanisms for uncertainty estimation because inaccurate or ungrounded outputs can mislead decision-making.
claimYuan et al. (2023) highlight the need for improved uncertainty estimation techniques to mitigate overconfidence in large language models.
claimEncouraging large language models to output uncertainty estimates or alternative explanations can address overconfidence and premature closure biases, particularly when users are guided to critically evaluate multiple options.
procedureEffective strategies for addressing poor calibration in large language models include probabilistic modeling, confidence-aware training, and ensemble methods, which enable models to provide uncertainty estimates alongside predictions.
