Subject [jira] [Commented] (SPARK-5226) Add DBSCAN Clustering Algorithm to MLlib
Date Mon, 21 Dec 2015 22:49:46 GMT

    [ https://issues.apache.org/jira/browse/SPARK-5226?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15067200#comment-15067200

mustafa elbehery commented on SPARK-5226:
-----------------------------------------

Better Implementation, based on research paper for parallel DBSCAN can be found here. https://github.com/irvingc/dbscan-on-spark
.. 

The approach solved bottleneck of reduce step, in which discovered clusters are merged.

Hope it helps.

> MLlib is all k-means now, and I think we should add some new clustering algorithms to
it. First candidate is DBSCAN as I think.
