Stanford Statistical Learning Theory – Lecture Notes [pdf] (web.stanford.edu)

Nice thanks. I've read the first chapter on online learning - that's close to a problem I have - I think it's very well written, but what happens when assumptions fall (e.g. convexity) is left for the reader to guess (which is ok, it's just my obsession)

This seems interesting. There are exercises on the corresponding course page. Unfortunately, the solutions are not public.
