Subject [jira] [Commented] (SPARK-5436) Validate GradientBoostedTrees during training
Date Thu, 29 Jan 2015 02:49:34 GMT

    [ https://issues.apache.org/jira/browse/SPARK-5436?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14296301#comment-14296301

Chris T commented on SPARK-5436:
--------------------------------

I may be able to attempt this, but I'm not confident I'll be able to implement a solution
(or even one of sufficient quality). I only wrote my first line of scala about a week ago,
so I'm still finding my way around how things work. If I can come up with something, I'll
share it...

> For Gradient Boosting, it would be valuable to compute test error on a separate validation
set during training.  That way, training could stop early based on the test error (or some
other metric specified by the user).
