public interface NeighborhoodFunction

Defines how a neighborhood function should work in competitive training. This is most often used in the training process for a self-organizing map. This function determines to what degree the training should take place on a neuron, based on its proximity to the "winning" neuron.

Method Summary

Modifier and Type	Method and Description
double	function(int currentNeuron, int bestNeuron) Determine how much the current neuron should be affected by training based on its proximity to the winning neuron.
double	getRadius()
void	setRadius(double radius) Set the radius.

Method Detail

function

double function(int currentNeuron,
                int bestNeuron)

Determine how much the current neuron should be affected by training based on its proximity to the winning neuron.

Parameters:

currentNeuron - THe current neuron being evaluated.

bestNeuron - The winning neuron.

Returns:

The ratio for this neuron's adjustment.

getRadius

double getRadius()

Returns:

The radius.

setRadius

void setRadius(double radius)

Set the radius.

Parameters:

radius - The new radius.
