zhengruifeng created SPARK-27944: ------------------------------------ Summary: Unify the behavior of checking empty output column names Key: SPARK-27944 URL: https://issues.apache.org/jira/browse/SPARK-27944 Project: Spark Issue Type: Improvement Components: ML Affects Versions: 3.0.0 Reporter: zhengruifeng
In some algs (LDA, DT, GBTC, SVC, LR, MLP, NB), the transform method will check whether an output column name is empty, and if all names are empty, it will log a warning msg and do nothing. It maybe better to make other algs (regression, ovr, clustering, als) also check the output columns before transformation. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
