Hi,
does someone know how the error of the neural network is computed when setting up these command lines:
net.performParam.normalization = 'standard'
net.performFcn = 'mse'
In the matlab documentation there is only written, that it normalizes errors between -2 and 2, corresponding to normalizing outputs and targets between -1 and 1. But i can't figure out the formular being used.
I will be very thankful if someone can tell me the formular.

It is just a straightforward linear transformation. For the target, t:
tn = a*t +b
-1 = a*tmin + b
1 = a*tmax + b
Just solve for a and b. Then plug in
t = (tn-b)/a
Hope this helps
Thank you for formally accepting my answer
Greg
