I can't see support in his article that 100% accuracy in a test set is categorically sub-optimal, as opposed to merely irrelevant, although he does later mention manipulating the data set to achieve 100% accuracy, which is, obviously, problematic.
Jun 14, 2017 at 17:19 comment added DukeZhou The concept of a solved game may be useful. If you have 100% accuracy, the problem is tractable, which is rarely the case in highly complex systems. ML is proving useful in tackling intractable problems, but in a condition of intractability, here a function of bounded rationality, you never have perfect certainty, only perceived optimality. The ML system may even get it right 100% of the time in a given sample, but that is no guarantee it will always do so.
