hello can I know how to train features using nntool neural network matlab.I'd extract the feature using principal component analysis as I get the eigenvalue of ROI image.I used this coding in matlab
[pc, score,lat,tsq] = princomp(x)
I'd save the lat value in a directory.Now, can you show me how to train this value to nntool in matlab?if you have any tutorial that I can learn is good.I want to use backpropagation nn.Can I know how to set the target value.Kindly respond to this question.
