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

Interface SMNumericExponential

All Superinterfaces:

SimilarityMeasure, SMNumeric

All Known Implementing Classes:

SMNumericExponentialImpl

public interface SMNumericExponential
extends SMNumeric

Another possibility to describe the similarity between two numeric values is by an exponential function. The semantics of such a similarity function is that little differences between the two values cause a big decrease of similarity. The larger the parameter $\alpha$ the faster is the decrease.
