Hi,
I am using check_grad from scipy for gradient checking of my mlp
implementation and I am not sure I am using it right, because it doesn't
work even on very trivial implementation of mlp. I have written a small
implementation of computing a gradient of mlp:
https://gist.github.com/2959786 I think I must be overlooking some stupid
mistake, because this implementation is very straightforward, but the
computed gradient is far from approximated one.
Any ideas where I am making a mistake?
Thanks
David
