Package de.uni_trier.wi2.procake.similarity.base.numeric

Interface SMNumericThreshold

All Superinterfaces:

SimilarityMeasure, SMNumeric

All Known Implementing Classes:

SMNumericThresholdImpl

public interface SMNumericThreshold
extends SMNumeric

Threshold functions should be used if there is the possibility that the contribution of an attribute to the utility is binary in the sense that up to a certain difference the case is useful and beyond it is not useful.
