All Implemented Interfaces:

java.io.Serializable

public class AboveModifier

extends ModifierFunction

implements java.io.Serializable

Concrete implementation of the above modifier. Consider the following example:

Description	Visual Representation
Unmodified fuzzy value: this is the unmodified fuzzy value to which the modifier is applied.
After Above modifier applied: the ABOVE modifier identifies the first x value at which the maximum value is reached. All membership values below this point are set to zero and all membership values above this value are set to 1-y. For convex fuzzy sets this gives an intuitive result.

Method Detail

call

public nrc.fuzzy.FuzzyValue call(nrc.fuzzy.FuzzyValue fv)

Creates a new FuzzyValue by applying the above modifier to an existing FuzzyValue. Above identifies the first x value at which the maximum value is reached. All membership values below this point are set to zero and all membership values above this value are set to 1-y. For convex fuzzy sets this gives an intuitive result.

Specified by:

call in class ModifierFunction

Parameters:

fv - the fuzzy value to which the below modifier is applied.

Parameters:

a - the fuzzy set to be modified
