I have seen a few times people using -1 as opposed to 0 when working with neural networks for the input data. How is this better and does it effect any of the mathematics to implement it?

Edit: Using feedforward and back prop

Edit 2: I gave it a go but the network stopped learning so I assume the maths would have to change somewhere?
