Constructor Detail

FuzzyFingerprintingEncoding.FuzzificationScheme

public FuzzyFingerprintingEncoding.FuzzificationScheme()

The default constructor. Initializes the interval boundaries with {0.5} to create the two intervals [0, 0.5] and (0.5, 1].

FuzzyFingerprintingEncoding.FuzzificationScheme

public FuzzyFingerprintingEncoding.FuzzificationScheme(double[] intervalBoundaries)

The explicit constructor. Initializes the fuzzification scheme with user defined interval boundaries. All boundaries have to be defined in the range (0, 1).

Parameters:

intervalBoundaries -

Method Detail

evaluate

public double evaluate(double value)

Applies the fuzzification scheme to the given value and returns it fuzzified representation.

Parameters:

value - a normalized deviation in the range of [0, 1]

Returns:

the fuzzified representation as a double value

locate

public int locate(double value)

Finds the index of the interval the value corresponds to.

Parameters:

value - a normalized deviation in the range of [0, 1]

Returns:

the index of the corresponding interval

getIntervalBoundaries

public double[] getIntervalBoundaries()

Returns the internal interval boundaries.

Returns:

a number of doubles which represent the interval boundaries

setIntervalBoundaries

public void setIntervalBoundaries(double[] intervalBoundaries)

Sets the internal interval boundaries.

Parameters:

intervalBoundaries - the user defined interval boundaries
