I have trained a neural network and got the below regression plot.
First of all I have nomalized every sample, by substracting its mean value over the samples and dividing this with its standard deviation. So that all input and output is normalized and in the same range. Is that allowed, or do I introduce any errors into my data.?
I have tried several network structures and always get such a cross in the regression plot, but as I guess, some of the output data seems to be insensitive to the input data. Is that right? If so, how can I check that.
Thanks for your help! Best regards,
