LLM评估置信区间因数据聚类而过于狭窄

评估语言模型的常见假设是每个测试示例都是独立的,但在实践中这通常会被违反。当示例是聚类的(例如,来自同一文档的多个问题或同一对话的多个轮次)时,它们携带重叠的信息,导致置信区间比应有的更窄。这种统计偏差可能导致研究人员错误地认为他们取得了显著的改进,而实际上并没有。解决方案是通过对整个聚类进行重采样,而不是对单个示例进行重采样,以准确反映有效的样本量并纠正置信区间宽度。 AI

影响 突出了常见LLM评估实践中的一个关键缺陷,可能使过去的基准测试结果无效,并需要重新评估模型改进。

    您的评估置信区间假设示例独立。您的示例是聚类的。

    <p>Every binomial confidence interval you have ever computed on an eval pass rate, Wald, Wilson, Clopper-Pearson, all of them, rests on one assumption: each example is an independent draw. Most eval sets violate it. You have 40 questions generated from the same 8 documents, or 20…
