Class SOMPattern

java.lang.Object

org.encog.neural.pattern.SOMPattern

All Implemented Interfaces:

NeuralNetworkPattern

public class SOMPattern
extends Object
implements NeuralNetworkPattern

A self organizing map is a neural network pattern with an input and output layer. There is no hidden layer. The winning neuron, which is that neuron with the higest output is the winner, this winning neuron is often used to classify the input into a group.

Method Detail

addHiddenLayer

public void addHiddenLayer(int count)

Add a hidden layer. SOM networks do not have hidden layers, so this will throw an error.

Specified by:

addHiddenLayer in interface NeuralNetworkPattern

Parameters:

count - The number of hidden neurons.

clear

public void clear()

Clear out any hidden neurons.

Specified by:

clear in interface NeuralNetworkPattern

generate

public MLMethod generate()

Generate the RSOM network.

Specified by:

generate in interface NeuralNetworkPattern

Returns:

The neural network.

setActivationFunction

public void setActivationFunction(ActivationFunction activation)

Set the activation function. A SOM uses a linear activation function, so this method throws an error.

Specified by:

setActivationFunction in interface NeuralNetworkPattern

Parameters:

activation - The activation function to use.

setInputNeurons

public void setInputNeurons(int count)

Set the input neuron count.

Specified by:

setInputNeurons in interface NeuralNetworkPattern

Parameters:

count - The number of neurons.

setOutputNeurons

public void setOutputNeurons(int count)

Set the output neuron count.

Specified by:

setOutputNeurons in interface NeuralNetworkPattern

Parameters:

count - The number of neurons.
