UnverifiedMachine learning models may overfit specific training samples and inadvertently reproduce details of the original data when generating content, a phenomenon known as training data memorization.80% similarVerifiedData contamination refers to test problems having already appeared in pretraining corpora, causing a model's high scores to more closely reflect memorization rather than reasoning.79% similarUnverifiedBenchmark contamination refers to the situation where benchmark questions have entered a model's training data, causing the model to "recall answers" rather than genuinely reason, inflating benchmark scores and failing to reflect actual capability.78% similarUnverifiedThe data contamination problem refers to the possibility that a model may have already encountered ideas or partial proofs during training that researchers have not yet formally published.77% similarUnverified蒸馏训练范式导致开源模型学习到经过高度过滤、几乎不包含失败和纠错过程的数据分布，使模型形成不愿自我纠正的性格77% similar
