When I generate a Matlab function of a neural network, it comes with the normalization/re-normalization constants. Will these constants affect the neural network performance on another data set? Why?
The normalization/re-normalization (for example, mapping the data to [-1,1] or [0,1]) is built for the training data. What does ...
