MATLAB: How create NN ??

feed forwordMATLABneural networkstoolbox

How many layers are hidden ? Is it Backpropagation network ?
net = newff(minmax(alphabet),[S1 10 S2],{'logsig' 'logsig' 'logsig' },'traingdx');
net.LW{2,1} = net.LW{2,1}*0.01;
net.b{2} = net.b{2}*0.01;
net.performFcn = 'mse';
net.trainParam.show = 20;
net.trainParam.epochs = 2000;
net.trainParam.mc = 0.95;
P = alphabet;
T = targets;
[net,tr] = train(net,P,T);

Best Answer

there are 2 hidden layers .
but you should know that there is a difference between the training method and the type of the network ;
back propagation is a training tool to NN , you can't say that it is a backpropagation network , because many different types of nets can be trained with back propagation
