MATLAB: Can target vector of neural network have sum of columns >1

Question

i have 56 classes ( 1 , 2, …..56) as output. i want to define target vector for neural network. I have converted classes into binary and output neurons are now 6. So for each column the value is >1. Is it ok? Can u help me to write a code to convert 6 output into original classes?

Answer 1

No! Target columns should be columns of eye(56);

 truclassindices = vec2ind(target);
 target          = ind2vec(truclassindices);
 ...
 output          = net(input);
 estclassindices = vec2ind(output);

Hope this helps

Thank you for formally accepting my answer
