MATLAB: Cross validation, neutal networks, doubt

Question

Hello everybody,

I'm seriously concerned about the matlab functions that are used to make neural networks. I need to make a neural network able to get 3 sets of vectors: a training, a validation and a testing set. The problem is: the newfit/newff function gets the set with all vectors and just uses the dividerand function on it (which is too much automatic). So, I already have the 3 sets and I need to use the newfit and the train functions using the sets I've already prepared. Any suggestions?

Thanks in advance, Guilherme

Answer 1

You can specify the subsets using

 net.divideFcn = 'divideind'
 help divideind
 doc divideind

Hope this helps
