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?

Neural Network Output Grouping 0.5?

as seen on Stack Overflow - Search for 'Stack Overflow'
I tried to write a Neural Network system, but even running through simple AND/OR/NOR type problems, the outputs seem to group around 0.5 (for a bias of -1) and 0.7 (for a bias of 1). It doesn't look exactly "wrong"... The 1,1 in the AND pattern does seem higher than the rest and the 0,0 in the OR… >>> More
