Class RbfRandomCenterSelector

java.lang.Object
  org.joone.util.AbstractConverterPlugIn
      org.joone.util.ConverterPlugIn
          org.joone.util.RbfRandomCenterSelector

All Implemented Interfaces:

java.io.Serializable, PlugInListener

public class RbfRandomCenterSelector
extends ConverterPlugIn

This plug in is used to select fixed centers for Gaussian RBF layers randomly from the input data. Therefore, I implemented the selector as a plug in, because this way I can easily select centers randomly from the input.

Constructor Detail

RbfRandomCenterSelector

public RbfRandomCenterSelector(RbfGaussianLayer aRbfGaussianLayer)

Creates a new instance of RbfRandomCenterSelector

Parameters:

aRbfGaussianLayer - the RBF Gaussian layer to get the number of nodes.

Method Detail

convert

protected boolean convert(int serie)

Description copied from class: AbstractConverterPlugIn

Applies the conversion on the Nth serie of the buffered pattern data. The method is abstract and should be overridden by the implementing class. Implementing classes can obtain the input patterns by calling the AbstractConverterPlugIn.getInputVector() method. The result is a Vector of Pattern objects which this method should use by converting the requested serie.

Specified by:

convert in class AbstractConverterPlugIn

Parameters:

serie - the serie to convert

getGaussianParameters

public RbfGaussianParameters[] getGaussianParameters()

Gets the parameters for the different nodes in a RBF layer.

Returns:

the parameters for the different nodes in a RBF layer.

getMaxDistance

protected double getMaxDistance(java.util.Vector aPatterns,
                                int[] anIndexes)

Gets the maximum distance between centers.

Parameters:

aPatterns - all the input patterns (which might have been selected to become a center).

anIndexes - the indexes of the selected centers.

getDistance

protected double getDistance(Pattern aCenter1,
                             Pattern aCenter2)

Gets the distance between two centers.

Parameters:

aCenter1 - the first center.

aCenter2 - the second center.

Returns:

the distance between the two centers.
