Hi I got two questions about the nnet function in R. I would be thankful to
have an answer.
1) Does the function intrinsically normalize the X and Y matrices before
the training, or normalization should be
done by the user.
2) I need to understand the $wts matrix. I do imagine that it is a single
column transformation of the two
matrices of weighs (input to hidden Ninputs+1 x Nodes) and hidden to output
(Nodes+1 x Noutputs).
Thanks
