English(EN) Benchmark Contamination 101: How Train/Test Overlap Inflates Leaderboard Scores (and How to Catch It)

基准污染夸大AI模型分数;检测方法说明

基准污染,也称为训练/测试重叠或数据泄露,是指测试示例或其近乎重复的样本包含在模型的训练数据中。这会导致排行榜分数虚高,因为模型会记住答案而不是泛化,从而造成能力上的虚假印象。文章概述了三种检测这种污染的方法:n-gram重叠、金丝雀字符串和成员推理,并强调由于评估环境中固有的风险以及基准的过时,需要仔细审查自我报告的分数。 AI

影响 强调了严格评估实践的必要性,以确保AI模型性能指标的可靠性并反映真实的泛化能力。

    基准测试污染101:训练/测试重叠如何夸大排行榜分数(以及如何发现它)

    <h2> TL;DR </h2> <p>A leaderboard number is only as trustworthy as the gap between what a model trained on and what it was tested on. When test examples (or near-duplicates of them) leak into pretraining or fine-tuning data, the model memorizes answers instead of generalizing, an…
