Re #20: I think there are a lot of things that people think of as "statistical" that have no "theory about the problem domain" in them, eg, PCA, linear discriminant analysis, regression. Even saying they're thought of as statistical is coming down a bit too much on one side: I'm pretty sure virtually every introductory machine learning course would cover them as well.
