>The feedback/back-propagation is very similar i really wish people wouldn't say these things just to sound smart. it confuses people that don't know better. feedback loops have nothing to do with backprop, which is just a way to factorize the jacobian into matrix vector products instead of matrix matrix products. do you have some proof (and it would require a proof) that PID controllers actually compute the gradient of a function with respect to n-inputs? because that's what backprop does.
