Class ElmanPattern

java.lang.Object
  org.encog.neural.pattern.ElmanPattern

All Implemented Interfaces:

NeuralNetworkPattern

public class ElmanPattern
extends Object
implements NeuralNetworkPattern

This class is used to generate an Elman style recurrent neural network. This network type consists of three regular layers, an input output and hidden layer. There is also a context layer which accepts output from the hidden layer and outputs back to the hidden layer. This makes it a recurrent neural network. The Elman neural network is useful for temporal input data. The specified activation function will be used on all layers. The Elman neural network is similar to the Jordan neural network.
