Joseph K. Bradley created SPARK-15617:
-----------------------------------------
Summary: Clarify that fMeasure in MulticlassMetrics and
MulticlassClassificationEvaluator is "micro" f1_score
Key: SPARK-15617
URL: https://issues.apache.org/jira/browse/SPARK-15617
Project: Spark
Issue Type: Documentation
Components: Documentation, ML, MLlib
Reporter: Joseph K. Bradley
Priority: Minor
See description in sklearn docs:
[http://scikit-learn.org/stable/modules/generated/sklearn.metrics.f1_score.html]
I believe we are calculating the "micro" average for {{val fMeasure: Double}}.
We should clarify this in the docs.
I'm not sure if "micro" is a common term, so we should check other libraries
too.
