Subject [jira] [Commented] (SPARK-14682) Provide evaluateEachIteration method or equivalent for spark.ml GBTs
Date Tue, 14 Mar 2017 00:32:41 GMT

    [ https://issues.apache.org/jira/browse/SPARK-14682?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15923309#comment-15923309
] 

Joseph K. Bradley commented on SPARK-14682:
-------------------------------------------

[~podongfeng]  Sorry for the slow response.  To clarify, spark.mllib's GBT provides a public
API for this method.  This JIRA is for adding a similar public API for GBTClassificationModel
and GBTRegressionModel in spark.ml.
