How many hidden neurons should I use in my neural network?

by  Predictor  Posted    (Edited  )
Optimal neural architecture parameters depend on many factors, and there is no simple way to determine what these are short of actually building complete models. Formulas which are often given are merely heursitics and should be taken as, at most, a suggested starting point. Consult the comp.ai.neural-nets (Usenet) FAQ, which can be found at:

ftp://ftp.sas.com/pub/neural/FAQ.html

Specifically, see this section:

I will recommend that one shoot for an effective neural network, rather than the optimal one, which will still require some experimentation.
