-----------------------------------
Why was mahout-68 cloned to produce this issue? It seems like the same thing.

[jira] Updated: (MAHOUT-73) addPoint, computeCentroid can be
optimized by using vector operators
Posted by "Pallavi Palleti (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/MAHOUT-73?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Pallavi Palleti updated MAHOUT-73:
----------------------------------
Attachment: MAHOUT-73.patch
We can use Vector operators in addPoint and computeCentroid methods of Canopy class. There by, this can be optimized for Sparse vector.Also, by using vector operators, we are hiding the implementation details and reusing the existing code in Sparse Vector, Dense Vector classes.
