I want to calculate ( Mean Square Error , Normalized Mean Square Error , Correlation Coefficient ) for the output result of neural network using matlab code ...
the Data are a group of different images, its features were extracted using PCA and then entered into the Nueral Network.
How can I know about system performance ?
PLZ any help .. thanks

inputs = x_test ; % your test data inputs
targets = y_test ; % your test data targets
P = net(inputs);
Error = targets - P;
MSE = mse(targets,P);
NMSE = (mean(error.^2)) / (mean(var(targets',1)));
