Miao Wang commented on SPARK-14900: ----------------------------------- Yes, "accuracy" makes more sense for binary classification problems. I will create a JIRA for it and work on it. For the MulticalssMetrics, I will make changes to deprecate "precision" by accuracy. > spark.ml classification metrics should include accuracy > ------------------------------------------------------- > > Key: SPARK-14900 > URL: https://issues.apache.org/jira/browse/SPARK-14900 > Project: Spark > Issue Type: New Feature > Components: ML > Reporter: Joseph K. Bradley > Priority: Minor > > To compute "accuracy" (0/1 classification accuracy), users can use > {{precision}} in MulticlassMetrics and > MulticlassClassificationEvaluator.metricName. We should also support > "accuracy" directly as an alias to help users familiar with that name. -- 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
