Autograd can automatically differentiate native Python
and Numpy code. It can handle a large subset of Python
features, including loops, ifs, recursion and closures,
and it can even take derivatives of derivatives of
derivatives. It supports reverse-mode differentiation
(a.k.a. backpropagation), which means it can efficiently
take gradients of scalar-valued functions with respect to
array-valued arguments, as well as forward-mode differentiation,
and the two can be composed arbitrarily. The main intended
application of Autograd is gradient-based optimization
