Insufficient Information.
What versions of Matlab & NNToolbox?
What kind of physical problem are you trying to solve?
Regression or Classification?
What are your inputs and outputs?
Number of input/output training pairs: Ntrn = 35
Input vector dimensionality: I = ?
Output vector dimensionality: O = 10
One hidden layer is sufficent; For I-H-O node topology:
Number of training equations Neq = Ntrn*O
Number of unknown weights Nw = (I+1)*H+(H+1)*O
For robust solution want Neq >> Nw or
H << (Neq-O)/(I+O+1)
size(p) = [I Ntrn]
size(t) = [O Ntrn]
See NNTB documentation for examples.
