Ram Sriharsha created SPARK-7690: ------------------------------------ Summary: MulticlassClassificationEvaluator for tuning Multiclass Classifiers Key: SPARK-7690 URL: https://issues.apache.org/jira/browse/SPARK-7690 Project: Spark Issue Type: Improvement Components: ML Reporter: Ram Sriharsha
Provide a MulticlassClassificationEvaluator with weighted F1-score to tune multiclass classifiers using Pipeline API. MLLib already provides a MulticlassMetrics functionality which can be wrapped around a MulticlassClassificationEvaluator to expose weighted F1-score as metric. The functionality could be similar to scikit(http://scikit-learn.org/stable/modules/generated/sklearn.metrics.f1_score.html) in that we can support micro, macro and weighted versions of the F1-score (with weighted being default) -- 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
