Method Detail

getMeritOfSplit

public double getMeritOfSplit(DoubleVector[] preSplitDist,
                              DoubleVector[][] postSplitDists)

Specified by:

getMeritOfSplit in interface MultiLabelSplitCriterion

getBranchSplitVarianceOutput

public double[] getBranchSplitVarianceOutput(DoubleVector[] postSplitDists)

getBranchesSplitMerits

public double[] getBranchesSplitMerits(DoubleVector[][] postSplitDists)

Specified by:

getBranchesSplitMerits in interface MultiLabelSplitCriterion

getMeritOfSplitForOutput

protected double getMeritOfSplitForOutput(DoubleVector[] preSplitDist,
                                          DoubleVector[][] postSplitDists,
                                          int outputAttributeIndex)

getMeritOfSplitForOutput

protected double getMeritOfSplitForOutput(DoubleVector preSplitDist,
                                          DoubleVector[] postSplitDists)

getRangeOfMerit

public double getRangeOfMerit(DoubleVector[] preSplitDist)

Specified by:

getRangeOfMerit in interface MultiLabelSplitCriterion

getDescription

public void getDescription(java.lang.StringBuilder sb,
                           int indent)

Description copied from interface: MOAObject

Returns a string representation of this object. Used in AbstractMOAObject.toString to give a string representation of the object.

Specified by:

getDescription in interface MOAObject

Parameters:

sb - the stringbuilder to add the description

indent - the number of characters to indent

prepareForUseImpl

protected void prepareForUseImpl(TaskMonitor monitor,
                                 ObjectRepository repository)

Description copied from class: AbstractOptionHandler

This method describes the implementation of how to prepare this object for use. All classes that extends this class have to implement prepareForUseImpl and not prepareForUse since prepareForUse calls prepareForUseImpl.

Specified by:

prepareForUseImpl in class AbstractOptionHandler

Parameters:

monitor - the TaskMonitor to use

repository - the ObjectRepository to use
