All Implemented Interfaces:

java.io.Serializable, InputPatternListener, Learnable, LearnableSynapse, NeuralElement, OutputPatternListener, Inspectable, InputSynapse, PlugInListener

public class LearningSwitch
extends InputSwitchSynapse

This class is useful to switch the input data set of a neural network from a training set to a validation set depending on the 'validation' parameter contained in the Monitor object. Very useful during a training phase to test the generalization capacity of the neural network with a validation data set never seen before.
