You can specify the performance function in patternnet as crossentropy, and specify the performance weights to perform class balancing in Pattern Recognition Network.

As far as I understand this, performance weights are not specified before the training step. But class balancing will affect the training, right?

performance weights should be specified for training. greg
Can you provide instructions on or an example of how performance weights are to be specified during training? The parameter perfWeights is not a performParam as far as I see.
net = feedforwardnet(10);
net.performFcn = 'crossentropy';
net.performParam.regularization = 0.1;
net.performParam.normalization = 'none';
