- lumost 4y agoBlack box ml model take the to a new level however. You can fit a model to anything, even if it lacks a causal relationship. If you setup the test set in such a way that it overlaps with the train set- then you'll get a positive result. You may think that you haven't overlapped the sets... But in practice most datasets have large numbers of duplicates once some irrelevant random variable is removed (eg time).
