All Implemented Interfaces:

ConfigurationListener, PreviewListener, ParameterHandler, LoggingHandler

public class RandomClustering
extends AbstractClusterer

Returns a random clustering. Note that this algorithm does not garantuee that all clusters are non-empty. This operator will create a cluster attribute if not present yet.

Method Detail

generateClusterModel

public ClusterModel generateClusterModel(ExampleSet exampleSet)
                                  throws OperatorException

Description copied from class: AbstractClusterer

Generates a cluster model from an example set. Called by AbstractClusterer.apply().

Specified by:

generateClusterModel in class AbstractClusterer

Throws:

OperatorException

getParameterTypes

public java.util.List<ParameterType> getParameterTypes()

Description copied from class: Operator

Returns a list of ParameterTypes describing the parameters of this operator. The default implementation returns an empty list if no input objects can be retained and special parameters for those input objects which can be prevented from being consumed.

Specified by:

getParameterTypes in interface ParameterHandler

Overrides:

getParameterTypes in class Operator

getInputDescription

public InputDescription getInputDescription(java.lang.Class cls)

Indicates that the consumption of example sets can be user defined.

Overrides:

getInputDescription in class Operator
