Field Details

valBelowZero

protected double valBelowZero

valBelowZero will influence local similarity in the following way: (1+valBelowZero) * sim - valBelowZero

currentCalcInstance

protected DTW currentCalcInstance

Instance used for the current/last calculation

Constructor Details

SMListDTWImpl

public SMListDTWImpl()

Method Details

compute

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

Specified by:

compute in interface SimilarityMeasure

Returns:

computeDTWSim

protected SimilarityImpl computeDTWSim(DataObject originalQueryObj,
 DataObject originalCaseObj,
 DTW dtwCalculation,
 SimilarityValuator valuator)

isSimilarityFor

public boolean isSimilarityFor(DataClass dataclass,
 String orderName)

Specified by:

isSimilarityFor in class SimilarityMeasureImpl

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.

getValBelowZero

public double getValBelowZero()

Specified by:

getValBelowZero in interface SMListDTW

setValBelowZero

public void setValBelowZero(double val)

Description copied from interface: SMListDTW

Set the stretching factor to 1 + val.

Specified by:

setValBelowZero in interface SMListDTW

getCalcInstance

public DTW getCalcInstance()

Specified by:

getCalcInstance in interface SMListDTW
