There are several distinct implementations available online. Also, Yu Lee and I have some experience on developing hierarchical clustering (clustering the data with arbitrary shape through connectivity-based clustering) on hadoop.
If you think this is OK, Yu Lee and I can take this task of implementation, test, and maintenance. Also, we would periodically report the progress. We can fork the mahout from github and conduct the implementation independently. 2013/5/7 Ted Dunning (JIRA) <j...@apache.org> > > [ > https://issues.apache.org/jira/browse/MAHOUT-1206?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13651369#comment-13651369] > > Ted Dunning commented on MAHOUT-1206: > ------------------------------------- > > Do you know of scalable algorithms for these other algorithms? > > Is there a demonstrated need?
