How does a large company with million if images make sure there aren't very similar copies in not the training set and validation set? Seems like you could be accidentally over training if there's a lot of copies of very similar images. (For example, there's going to be a lot more pictures of the Taco Bell Chihuahua compared to other Chihuahuas, and possibly some of those pictures have enough similarity to make over fitting possible.

To be fair, humans have this problem as well; if I showed you an octagonal red sign that had the words "GO" inscribed in the middle you may still mistake it for a stop sign at first.
