I had a quick look at theano. It looks more like symbolic
differentiation. Is that right?
How does it handle functions with loops in the body?
Also, I have another AD tool on github
(http://github.com/b45ch1/algopy/tree/master) that implements its own
graph structure at the moment.
It might be nice if I could use theano internally to optimize the
computational graph. Do you think that might be possible?
