[jira] [Commented] (SOLR-10786) Add DBSCAN clustering Streaming
Evaluator
[ https://issues.apache.org/jira/browse/SOLR-10786?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16344035#comment-16344035 ]
Joel Bernstein commented on SOLR-10786:
---------------------------------------
Solr 7.3 has kmeans++, fuzzyKmeans clustering. But DBSCAN clustering just to slow I thought to be useful for the Solr users. I will try it again sometime to see if it was just how I put things together, but it was painfully slow compared to kmeans.
