proof bag of words

[walshbr]

i expanded on the bit to get a bit into how bag of words let's you do sentence similarity. Hopefully it's not quite too far afield. It's a bit hand-wavy and gets away from topic modeling, but maybe still worth keeping in there in some capacity? At any rate, let me know what you think. I can shorten it if you want!

looks great! i think a really good explanation of the theory behind topic modeling.
