We should also check for implementations in other packages to find out what
arguments and argument names (including "micro" and "macro") are most common.
Perhaps R, Weka, etc.
> 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)
