AI总结:

本研究针对大语言模型输出看似正确但推理模式可能有误的问题,提出基于输入短语相互作用量化及配套指标的推理模式正确性评估方法,在法律LLM案例中验证了该问题的普遍存在。

摘要:

本文以法律大语言模型(LLM)为案例研究,提出一种分析大语言模型(LLMs)用于判断的推理模式的方法,旨在依据人类领域知识识别LLM潜在的错误表征。与传统针对语言生成结果的评估不同,我们提出评估LLM在看似正确的输出背后,其详细推理模式的正确性。为此,我们量化LLM用作基本推理模式的输入短语之间的相互作用,因为近期的理论成果已证明基于相互作用的解释的忠实性具备若干数学保障。我们设计了一组指标来评估LLMs的详细推理模式。实验表明,即便语言生成结果看似正确,LLM用于法律判断的推理模式中仍有相当一部分可能呈现误导性或无关的逻辑。

英文摘要:

This paper presents a method to analyze the inference patterns used by Large Language Models (LLMs) for judgment in a case study on legal LLMs, so as to identify potential incorrect representations of the LLM, according to human domain knowledge. Unlike traditional evaluations on language generation results, we propose to evaluate the correctness of the detailed inference patterns of an LLM behind its seemingly correct outputs. To this end, we quantify the interactions between input phrases used by the LLM as primitive inference patterns, because recent theoretical achievements have proven several mathematical guarantees of the faithfulness of the interaction-based explanation. We design a set of metrics to evaluate the detailed inference patterns of LLMs. Experiments show that even when the language generation results appear correct, a significant portion of the inference patterns used by the LLM for the legal judgment may represent misleading or irrelevant logic.
