I know it’s a quite old article but I was wondering if you were able to give me more pointers about this sentence: “There are war stories of algorithms with data leakage running in production systems for years before the bugs in the data creation or training scripts were detected”.

I’m Denis, a PhD student at the ENS in Paris. Lately, I’ve been focus in formally proving the absence/presence of data leakage on machine learning code – in the data preparation phase. I would love to receive some suggestion/pointers of such problem in code snippets where data leakage happened in production! I don’t have a working tool yet, I’m still in the exploration phase to understand what are the ML scientist needs about data leakage.
