新的LCA-UQ方法增强了大型语言模型的不确定性估计

研究人员引入了一种名为标签置信度感知不确定性量化(LCA-UQ)的新方法,以提高大型语言模型(LLMs)不确定性估计的可靠性。该方法解决了现有方法的主要局限性,即现有方法主要使用来自多个样本的熵,而常常忽略候选答案的具体置信度。LCA-UQ利用点向Kullback-Leibler散度来更好地使采样输出的一致性与候选答案的校准相匹配。在各种LLMs和NLP数据集上的实证结果表明,LCA-UQ能有效捕捉采样结果与标签来源之间的细微差别,从而实现更优越的不确定性估计。 AI

影响 通过更好地识别潜在的幻觉或无效响应,提高了LLMs的可靠性。
