VerifiedBenchmark data contamination refers to the phenomenon where, after a test set is made public, its questions may appear in the pre-training corpora of subsequent models, causing scores to reflect memorization rather than genuine reasoning ability.78% similarUnverifiedOnce a public benchmark attracts widespread attention, it risks being targeted for optimization, and high scores do not necessarily reflect generalized reasoning ability.78% similarVerifiedDrift detection involves a trade-off: setting the threshold too sensitively leads to frequent false alarms and unnecessary retraining, while setting it too loosely may allow model performance to continuously degrade without being detected.77% similarVerified若用含测试集的全量数据计算均值和标准差,会导致预处理泄漏,使评估指标虚高,无法真实反映模型泛化能力76% similar
