Package libai.fuzzy.defuzzifiers

Class CenterOfArea

  • public class CenterOfArea
extends CenterOfGravity
    Defuzzifier method that calculates the value of x where the areas become equal in the aggregated function. Formally, CoA = Area(f, x0, CoA) = Area(f, CoA, xn) This implementation uses Riemann's sums and Binary search to locate the value of CoA, to a precision of 1.e-8

        public double getValue​(java.util.List<java.awt.geom.Point2D.Double> function)
        Description copied from class: CenterOfGravity
        Implements the center of gravity by calculating the Riemann's sums of the area using the trapezoidal rule. It assumes the x points are equally spaced across the whole domain of the function.
        Overrides:
        getValue in class CenterOfGravity
        Parameters:
        function - the list of points [x, f(x)] representing the function to analyze.
        Returns:
        the center of gravity of the function.
