> The implementation of mahout at present only using canopy algorithm creating initial cluster centroids for k-means.  It will calculate the distance from  each center to every point while iterating. But  the most import improvement of canopies is that needs only calculating the distance from each  center to a much smaller number of points which exists in the same canopy.
