> The main take away is that Machine Learning is Statistics. That and brute force computation. A lot of ML models use vastly more data and bigger feature sets than was feasible when these techniques were originally developed. Stepwise regression, lassos, cross validation, etc have become much more popular as raw computing power has increased.
