This command trains an MLP network using the Matlab style training algorithm. The method is based on a global learning rate parameter with a momentum term. By default one neuron for each input is used.
Example (ex5.7): Train a three-layer (input + hidden + output layer) MLP network with sine data using sigmoid activation functions in neurons. After training, save the network output.
