All Implemented Interfaces:

java.io.Serializable

public class IntensifyModifier

extends ModifierFunction

implements java.io.Serializable

Concrete implementaion of the intensify modifier. Consider the following example:

Description	Visual Representation
Unmodified fuzzy value: this is the unmodified fuzzy value to which the modifier is applied.
After intensify modifier applied: the INTENSIFY modifier returns the expanded FuzzyValue passed as its argument, having having performed the following modifications on it: if (0.0 <= y <= 0.5), y = 2*y2 if (0.5 < y <= 1.0), y = 1 - 2*(1-y)2 The has the effect of emphasizing the sections of the FuzzyValue that have a membership value greater than 0.5, and understating any sections of the FuzzyValue with a membership value less than or equal to 0.5.

Method Detail

call

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

Returns a new FuzzyValue object which represents the FuzzyValue argument after the application of the intensify modifier. The intensify modifier uses the following rules for application of modifiers and operators:

• if (0.0 <= y <= 0.5), y = 2*y²
• if (0.5 < y <= 1.0), y = 1 - 2*(1-y)²

Where y is the membership value of each point of the FuzzyValue.

Specified by:

call in class ModifierFunction

Parameters:

fv - the FuzzyValue to modify with the intensify hedge

Returns:

a new FuzzyValue object representing FuzzyValue argument after the application of the intensify hedge. This new FuzzyValue object has the same FuzzyVariable as the FuzzyValue argument.

call

public nrc.fuzzy.FuzzySet call(nrc.fuzzy.FuzzySet a)

Returns a new FuzzySet object which represents the FuzzySet argument after the application of the intensify modifier. The intensify modifier uses the following rules for application of modifiers and operators:

• if (0.0 <= y <= 0.5), y = 2*y²
• if (0.5 < y <= 1.0), y = 1 - 2*(1-y)²

Where y is the membership value of each point of the FuzzySet.

Specified by:

call in class ModifierFunction

Parameters:

a - the fuzzy set to be modified

Returns:

a new FuzzySet object representing FuzzySet argument after the application of the intensify hedge.
