it seems people call these techniques machine learning/AI simply because it sounds cooler: a lot of the techniques have a 30+ year history in statistics. this is the same story as neural networks: neural networks are just nested logistic regression, a technique with much history in statistics. a lot of high frequency trading is simply linear/logistic regression (on the right features of course). anything more complicated is too slow.
