[jira] [Commented] (SPARK-8069) Add support for cutoff to RandomForestClassifier

["holdenk (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SPARK-8069?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14650477#comment-14650477 ] 

holdenk commented on SPARK-8069:
--------------------------------

So I was looking at https://docs.google.com/document/d/1nV6m7sqViHkEpawelq1S5_QLWWAouSlv81eiEEjKuJY/edit?pli=1# and I can't comment or edit the design document so I figured I'd write my notes here ([~josephkb] if you could give me comment permission on the document that would be great).

The document calls for only having thresholds for ProbabilisticClassifier but also up above discusses having an implementation for both, which one do we want to do?
