Hi All I'm reading the code of SquaredEuclideanDistanceMeasure, the
"distance(double centroidLengthSquare, Vector centroid, Vector v)" method
confused me a lot, i don't know why we choose this expression
"centroidLengthSquare - 2 * v.dot(centroid) + v.getLengthSquared()" to
calculate the distance? What is the best case to use this Measure? BTW, I
think it would be great if we can have a wiki or some detail user guide or more
comments in the source code to explain each distance measure implementation,
that will really help, thanks guys. Cheers Ramon
