Class GaussWeight

  • All Implemented Interfaces:
    WeightFunction

    public final class GaussWeight
    extends java.lang.Object
    implements WeightFunction
    Gaussian weight function, scaled such that the result it 0.1 when distance equals the maximum, using \( \exp(-2.3025850929940455 \frac{\text{dist}^2}{\max^2}) \).
    Since:
    0.2

        Specified by:
        getWeight in interface WeightFunction
        Parameters:
        distance - distance of the query point
        max - maximum distance of all included points
        stddev - standard deviation (i.e. quadratic mean / RMS) of the included points
        Returns:
        weight for the query point
