All Implemented Interfaces:

java.lang.Cloneable, java.io.Serializable, SimilarityOperatorInterface

public class SimilarityByAreaOperator

extends SimilarityOperator

implements java.io.Serializable

A class that provides an operator to calculate the similarity between 2 fuzzy values. The similarity measure is the ratio of area of intersection to area of union of the fuzzy values.

The default similarity operator is the SimilarityByPossibilityOperator. This can be changed using the static setDefaultSimilarityOperator method of the FuzzyValue class.
