The 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.

UnverifiedSemi-automated data mining strategy: when one modality continuously detects a target for more than 8 consecutive frames while the other modality misses it entirely, a binary judgment is triggered to obtain missed-detection or false-positive samples.74% similarVerifiedStandardizing the entire dataset before splitting it leads to data leakage, exposing test set information to the training set.73% similarUnverified遇到某变量为空的报错时，应顺着数据流向前追溯，在报错处打断点逐个变量悬停查看值以定位源头71% similarUnverifiedOther common sources of data leakage include computing mean/standard deviation for normalization using the full dataset, using future time-point information in feature engineering, and failing to apply cross-validation isolation during target encoding.71% similarUnverified从事件监听打断点并沿调用栈逐层追溯，比盲目全局搜索效率更高且不易遗漏中间数据转换环节71% similar
