Regarding Neural network fitting tool

Hi I have two data sets 1. Training data: To train the neural network 2 test data: to use neural network to predict the result

I have used the training data to train the rquired neural model. Now I want to use the model to predict answers fpr my test data. But I dont know how to predict answer from my test data.

Please Help

Everything you need is stored in the training structure tr. Just type tr = tr with no semicolon to see what is there.

[ net tr Y E ] = train(net,x,t);

tstInd = tr.divideParam.testInd;

Ytst = Y(:,tstInd);

Etst = E(:,tstInd);

MSEtst = mse(Etst)

bestepoch = tr.best_epoch

MSEtst = tr.tperf(bestepoch)

Hope this helps.

Thank you for formally accepting my answer
