Xiangrui Meng resolved SPARK-4942. ---------------------------------- Resolution: Fixed Fix Version/s: 1.3.0 Issue resolved by pull request 3637 [https://github.com/apache/spark/pull/3637] > ML Transformers should allow output cols to be turned on,off > ------------------------------------------------------------ > > Key: SPARK-4942 > URL: https://issues.apache.org/jira/browse/SPARK-4942 > Project: Spark > Issue Type: Improvement > Components: ML > Affects Versions: 1.2.0 > Reporter: Joseph K. Bradley > Assignee: Joseph K. Bradley > Fix For: 1.3.0 > > > ML Transformers will eventually output multiple columns (e.g., predicted > labels, predicted confidences, probabilities, etc.). These columns should be > optional. > Benefits: > * more efficient (though Spark SQL may be able to optimize) > * cleaner column namespace if people do not want all output columns > Proposal: > * If a column name parameter (e.g., predictionCol) is an empty string, then > do not output that column. > This will require updating validateAndTransformSchema() to ignore empty > output column names in addition to updating transform(). -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
