Subject [jira] [Commented] (MAHOUT-887) Bottom Up Clustering
Date Tue, 15 Nov 2011 04:53:52 GMT

    [ https://issues.apache.org/jira/browse/MAHOUT-887?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13150234#comment-13150234

Paritosh Ranjan commented on MAHOUT-887:
----------------------------------------

To begin with, I will start with CanopyClustering merging clusters having single point till
the clusters (centroids) are within the user specified distance.I think it will be the smallest
step towards Bottom Up Clustering.

Is anyone having any thought on how to proceed better on this? If not, I will proceed and
provide a patch on this.

> Bottom up clustering is achieved by starting with small clusters/single points and then
merging clusters recursively which are closer than a specified control constraint.
