Neural Network: newton method vs MLP
Posted:
Feb 15, 2010 9:30 PM


I have implemented a Multilayer perceptron and would like to adapt my program so that I can use the Netwon Method.
I understand the following: MLP neuron(id).beta=(dy)*(1y*y); end % d: correct value, y: output value Newton: error term is now omitted: if method==3 neuron(id).beta=(1 y*y); end % Newton method (=j)
I now have to calculate the 'hessian'. Any suggestions where I can find a good examle how to do this are much appreciated.
