A side-note: Statistical classification is machine learning, which is a subset of AI. Or atleast, was a subset of AI when it was classified itself. Machine learning has a lot of overlap with artificial intelligence, and statistical classification is, pedantically, AI. On a more general note, AI is an extremely broad field and -- I am assuming this is where you're coming from -- is not limited to the whole General/Narrow/Vertical/Foo/Baz/Bar jumble mumble.
