Constructor Details

SMAggregateKMaximumImpl

public SMAggregateKMaximumImpl()

Method Details

compute

public Similarity compute(DataObject queryObject,
 DataObject caseObject,
 SimilarityValuator valuator)

Specified by:

compute in interface SimilarityMeasure

Returns:

getK

public int getK()

Specified by:

getK in interface SMAggregateKMaximum

Returns:

the k value for k-maximum

setK

public void setK(int k)

Description copied from interface: SMAggregateKMaximum

To use the k-Maximum Aggregation it is necessary to set the k value. k

Specified by:

setK in interface SMAggregateKMaximum

getSystemName

public String getSystemName()

Description copied from interface: SimilarityMeasure

The system name can be used to distinguish the similarity measures. Each similarity measure that can be instantiated contains a static final field called NAME representing the system name, e.g., SMAggregateEuclidian.NAME

The system name must also be given during initialization, see SimilarityModel.createSimilarityMeasure(String, DataClass).

Specified by:

getSystemName in interface SimilarityMeasure

Returns:

The system name of the similarity measure. This is equal to SimilarityMeasure.NAME.

initializeBasedOn

protected void initializeBasedOn(SimilarityMeasure base)

Description copied from class: SimilarityMeasureImpl

Initialize measure based on existing instance

Overrides:

initializeBasedOn in class SMAggregateWeightedImpl

Parameters:

base - similarity measure to base on
