UnverifiedThe way to avoid data leakage is to split data by individual — all augmented images derived from the same original image must go either entirely into the training set or entirely into the validation set.78% similarUnverifiedA leak-free benchmark means strictly avoiding the use of future information in data splitting and feature engineering, ensuring the fairness of evaluation and its practical deployment value.77% similarUnverifiedTwo practical principles for guarding against data leakage are developing a baseline intuition (knowing the normal performance range of features) and eliminating errors through architecture rather than relying on manual review.75% similarUnverifiedFor uncertain data errors, the prudent approach is to quarantine suspicious data to a dead-letter queue rather than making hasty modifications.73% similarUnverified在数据离开边界前应对敏感字段进行脱敏或最小化处理，以确保即使泄露也无害73% similar
