zhengruifeng commented on issue #24793: [SPARK-27944][ML] Unify the behavior of checking empty output column names URL: https://github.com/apache/spark/pull/24793#issuecomment-505387634 This pr can help to avoid uncessary computation. For example, in GMM, current impl always predict twice, one for `probabilityCol` and one for `probabilityCol`. if we only need probability, the first col can be skipped.
