| - | Note a couple of things about this code: first, it is fully vectorized. Second, the ''numerical_gradient'' function accepts a parameter called ''loss_function'' -- ''numerical_gradient'' is a higher-order function that accepts another function as an input. This numerical gradient calculator could be used to calculate gradients for any function. | + | Note a couple of things about this code: first, it is fully vectorized.

This numerical gradient calculator could be used to calculate gradients for any function. Third, you may wonder why my ''loss_function'' doesn't need the data! Since the data never changes, I curried it into my loss function, resulting in a function that only takes one parameter -- the matrix ''W''. |
