The mathematics of training a neural network. I understand how they work once trained, but that you can train them almost seems too good to be true.

On the contrary, this is a problem that goes "complicated-easy-complicated" the more you think about it. You're at stage two, so here's the mindfuck: Why aren't we constantly stuck at local minima? Surely these problems we're throwing at ANNs aren't all convex.

How do you KNOW you are not a local minima? You are putting the cart before the horse.
