Class PropagationSynapse

java.lang.Object
  org.encog.neural.networks.training.propagation.PropagationSynapse

public class PropagationSynapse
extends java.lang.Object

The back propagation training algorithms requires training data to be stored for each of the synapses. The propagation class creates a PropagationSynapse object for each of the synapses in the neural network that it is training.

Constructor Summary

PropagationSynapse(Synapse synapse)
Construct a PropagationSynapse object that corresponds to a specific synapse.

Method Summary

void	accumulateMatrixDelta(int i1, int i2, double value) Accumulate a matrix delta.
Matrix	getAccMatrixGradients()
Matrix	getDeltas()
Matrix	getLastMatrixGradients()
Synapse	getSynapse()
void	setLastMatrixGradients(Matrix d) Set the matrix gradients.

Parameters:

d - The matrix to set.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

Returns:

This object as a string.
