In my opinion, the first step should be to ensure your code is
efficient. The speed of Mathematica code can vary enormously with quite
For example, if the critical part of your NN calculation can be
expressed as matrix multiplication, try to do that, and make sure you
use packed arrays, or sparse arrays as appropriate.
