Method Details

getStepVec

public Vector getStepVec(DataObject queryObj,
 DataObject caseObj)

Description copied from interface: DP

Vector representing DP-specific possibilities associated with each step. This function is implemented by DTW and SWA individually.

Specified by:

getStepVec in interface DP

Returns:

A vector representing each step's values. (#val diagonal step#, #val horizontal step#, #val vertical step#, 0).

getAlignment

public DataObject[][] getAlignment()

Description copied from interface: DP

Returns the found alignment of the dp algorithm as a 2d array. return[0] und return[1] enthalten die alignments.

Specified by:

getAlignment in interface DP

Returns:

A 2d array containing the alignment.

getNormedSimilarityScore

public double getNormedSimilarityScore()

Description copied from interface: DP

Return the normalized similarity.

Specified by:

getNormedSimilarityScore in interface DP

Returns:

The normalized similarity score.

setStretchSim

public void setStretchSim(double valBelowZero)

Description copied from interface: DTW

Set the stretching factor to be used for local similarities.

Specified by:

setStretchSim in interface DTW

Parameters:

valBelowZero - The local sims will be mapped to the interval [-valBelowZero, 1]
