I've tried adding mapminmax() to my own feedforward calculation, but I was not able to replicate MATLAB's calculations. I would love to know. I need the hidden node values, and the only way to get those is to do so manually--ie no built in method in the net object. And, as a sanity check, it would be nice if I could match >predictions with the processing functions turned on.
Don't forget that targets are also normalized for training.
Therefore outputs have to be unnormalized in order to get the final answer.
