Neural network toolbox

Hi

I am trying to design a neural network using the NN toolbox, the toolbox set the only one hidden layer by default, My question is how can I add another hidden layer in the network

Thanks Ram

The method is not clear to me. Earlier when someone asked much the same question for newff(), my interpretation was:

It appears to me that the number of layers is one more than the number of size (Si) parameters that you provide. Thus,

newff(p,t,[3 3])

would, I think, create two hidden layers both with 3 neurons.

No promises, but you could try the experiment.

That is correct. However, there is seldom a need for more than one hidden layer.

For the earlier version of newff with size(p) = [I N], size(t) = [O N] and an I-H1-H2-O node topology:

net = newff(minmax(p),[H1 H2 O]);

instead of

net = newff(p,t,[H1 H2]);

In the newest version

net = fitnet([H1 H2]);

Hope this helps.
