I guess that depends on the size, dimensionality and sparseness of the data as well?
Great discussion @chris441!
SMILE author claims he writed fastest algorithms.
I really tried to, without being annoying, let people know there was a lot more here (in Clojure) than they thought. I was very, very happy to be on a Panel with Chris Lattner and would have enjoyed talking to just him quite a bit about some of my theories/ideas but the panel wasn't the place for that. I definitely had a chance to talk about clojisr though and this was the perfect forum 🙂.
