I do need some one to follow my code, i have attached my m-file here! I don’t know what the hell is wrong with my code whatever I do it works too good to be correct My neural network, no matter how many neurons I put for its hidden layer it works too good , I know there must be something wrong , if u can figure out where I am wrong , please let me know ,I got so frustrated by this program , what I am doing is a simple classification of the glass data which I got from here: http://archive.ics.uci.edu/ml/machine-learning-databases/glass/ I try to classify this data into 7 classes, no matter how many neurons I have in hidden layer the training and learning errors are about 0. How is it possible? I know I must be wrong somewhere, but I cannot figure it out:/

please help me with this!

if true
  %NET STRUCTURE

net=feedforwardnet(1);% i have changed number of neurons here

% but no matter what it is , it works %,i mean the learning error and

%test of error are close to zero:/

net.divideParam.trainRatio=0.9 net.divideParam.valRatio=0.1 net.divideParam.testRatio=0

%LEARNING PHASE

[net,tr]=train(net,OL,traininglabel); net.trainparam.epochs=1000; yt=net(OL); E_oL=mse(yt-traininglabel) learnigErrorofactualdata(ii,1)=E_oL;

%testing PHASE BY USING 20% OF ACTUAL DATA

kv=testdata'; Dv=testlable';

Ytest=net(kv); E_ov=mse(Ytest-Dv);

ValErofACtudata(ii,1)=E_ov end

i attached my m-file , please have a look on it ,thanks in advance , i do need help

Please explain and post your corrected code.

Did you do anything special to deal with the empty class 4?
