English(EN) RECOM: A Validity Discrimination Tradeoff in Automatic Metrics for Open Ended Reddit Question Answering

新的RECOM数据集揭示了LLM评估中指标的权衡

研究人员推出了RECOM,这是一个新的评估数据集,旨在评估开放式问答的自动指标,特别是针对LLM生成的文本。该数据集包含15,000个r/AskReddit问题及其真实的社区回复,突显了指标识别真实内容一致性(有效性)的能力与其对不同模型进行排名(区分能力)的能力之间的紧张关系。实验表明,虽然余弦相似度等指标在有效性方面表现出色,但在区分能力方面却表现不佳,而BERTScore精确率等指标在排名方面显示出潜力,但有效性较弱。研究表明,这种权衡是指标本身的固有属性,源于它们的表示设计,并建议沿两个轴报告指标,并包含一个随机基线。 AI

影响 强调了当前LLM评估指标的局限性,可能指导更强大的评估工具的开发。

    Automatic metrics are the default for evaluating LLM-generated text, yet a metric is quietly asked to do two jobs: tell genuine content alignment from surface coincidence (validity), and tell a better system from a worse one (discriminative power). On open-ended, opinion-driven q…
