Method Detail

compute

public double compute(double[] a,
             double[] b)

Computes the Hamming distance between two vectors. May cause a loss of precision, if the doubles are "really" doubles (in that case, please don't use).

Specified by:

compute in interface org.apache.commons.math3.ml.distance.DistanceMeasure

Parameters:

a - n-dimensional vector of values.

b - n-dimensional vector of values

Returns:

Hamming distance between a and b.
