Method Detail

setPreviousRun

public void setPreviousRun(GmeansSampling<I,D> previousRun)

Description copied from interface: IRerunnableSamplingAlgorithmFactory

Set the previous run of the sampling algorithm, if one occurred, can be set here to get data from it.

Specified by:

setPreviousRun in interface IRerunnableSamplingAlgorithmFactory<I extends INumericLabeledAttributeArrayInstance<? extends java.lang.Number>,D extends IDataset<I>,GmeansSampling<I extends INumericLabeledAttributeArrayInstance<? extends java.lang.Number>,D extends IDataset<I>>>

Parameters:

previousRun - Algorithm object of the previous of the sampling algorithm.

setClusterSeed

public void setClusterSeed(long clusterSeed)

Set the seed the clustering will use for initialization. Default is without a fix seed and the system time instead.

Parameters:

clusterSeed -

setDistanceMeassure

public void setDistanceMeassure(org.apache.commons.math3.ml.distance.DistanceMeasure distanceMeassure)

Set the distance measure for the clustering. Default is the Manhattan distance.

Parameters:

distanceMeassure -

getAlgorithm

public GmeansSampling<I,D> getAlgorithm(int sampleSize,
                                              D inputDataset,
                                              java.util.Random random)

Description copied from interface: ISamplingAlgorithmFactory

After the necessary config is done, this method returns a fully configured instance of a sampling algorithm.

Specified by:

getAlgorithm in interface ISamplingAlgorithmFactory<I extends INumericLabeledAttributeArrayInstance<? extends java.lang.Number>,D extends IDataset<I>,GmeansSampling<I extends INumericLabeledAttributeArrayInstance<? extends java.lang.Number>,D extends IDataset<I>>>

Parameters:

sampleSize - Desired size of the sample that will be created.

inputDataset - Dataset where the sample will be drawn from.

random - Random object to make samples reproducible.

Returns:

Configured sampling algorithm object.
