parallelize k-means sharing the predominance of canopies
--------------------------------------------------------
Key: MAHOUT-54
URL: https://issues.apache.org/jira/browse/MAHOUT-54
Project: Mahout
Issue Type: Improvement
Components: Clustering
Affects Versions: 0.1
Environment: OS Independent
Reporter: Jeremy Chow
Fix For: 0.1
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.
