English(EN) From Answers to Interpretations: Rethinking Ambiguity-Induced Aleatoric Uncertainty Estimation in LLMs

新的LLM不确定性估计方法绕过答案，降低成本

作者 PulseAugur 编辑部 · [1 个来源] · 2026-09-07 04:00

研究人员开发了一种新的方法来估计大型语言模型（LLM）中由歧义引起的随机不确定性，而无需模型生成答案。这种仅澄清的方法直接分析输入的可行解释空间，研究人员认为这比比较澄清输入答案的传统方法更有效，并且不易发生认知泄漏。据报道，新方法提高了AUROC分数，显著降低了计算成本，并产生了与认知不确定性相关性较低的估计值，这表明从解释而非响应中可以更好地捕捉歧义。 AI

影响这种新方法通过提高不确定性估计的准确性和效率，可能带来更可靠的LLM部署。

从答案到解读：重新思考LLM中由歧义引起的随机不确定性估计

arXiv:2609.04543v1 Announce Type: new Abstract: A key challenge in reliable LLM deployment is recognizing when uncertainty reflects irreducible variability in the task rather than limitations in the model's knowledge. In language tasks, a central source of such aleatoric uncertai…
