Well, where's the learning?

There's a general tendency to reclassify any kind of statistical analysis that produces a useful result as "machine learning", and I don't think it helps. For example there are lots of machine vision techniques; the neural net ones can sensibly be called "learning" but things like edge detection shouldn't be.

(also, just because something is taught in course X doesn't mean that it is X, it might be an embedded prerequisite)
