MATLAB: Neural Network retrieve test dataset to plot

Question

I am wanting to retrieve the data in the 'test' plot from training so that I can plot the data myself in a different format.

I can access the training, validation, test indices using [tr] but how do I find the network outputs for these to plot against the targets?

Answer 1

From either

 [ net tr y e ] = train( net, x, t );
 % or
 % [ net tr ] = train( net, x, t );
 % y = net(x);
 % e = t - y ; 
 ttrn = t(:,tr.trainInd);
 ytrn = y(:,tr.trainInd);

and similarly for yval and ytst.

Hope this helps.

Thank you for formally accepting my answer
