getSplitCriterion

public OraSplitCriterion getSplitCriterion()
                                    throws javax.datamining.JDMException

Returns the Split criterion for k-Means Clustering

Returns:

OraSplitCriterion

Throws:

javax.datamining.JDMException

setNumberOfBins

public void setNumberOfBins(int numberOfBins)

Sets the number of histogram bins. Specifies the number of bins in the attribute histogram produced by k-Means. Default value is 10.

Returns:

void

getNumberOfBins

public int getNumberOfBins()

Returns the number of histogram bins. Specifies the number of bins in the attribute histogram produced by k-Means.

Returns:

int

setBlockGrowth

public void setBlockGrowth(int blockGrowth)

Sets the growth factor for memory allocated to hold cluster data. Valid range > 1 and <= 5. Default value is 2.

Returns:

void

getBlockGrowth

public int getBlockGrowth()

Returns the growth factor for memory allocated to hold cluster data.

Returns:

int

setMinPercentageAtrrSupport

public void setMinPercentageAtrrSupport(double minPercentageAtrrSupport)
