4.1 How to Build a Neural Network?

You should have learned with the tutorial basic PLearn neural network. The class used is NNet.

Here is a basic NNet script object:

NNet(
nhidden =  10 ;
noutputs = 1 ;
output_transfer_func = "";
hidden_transfer_func = "tanh"  ;
cost_funcs = 1 [ mse ]  ;
optimizer = GradientOptimizer(
                start_learning_rate = .01;
                decrease_constant = 0;
                )

batch_size = 1  ;
initialization_method = "normal_sqrt"  ;
nstages = 500 ;
);
