[~josephkb] Please go ahead. Thanks for taking over shepherding. I really have
lots of PRs waiting to review.
> Expose raw prediction scores in MultilayerPerceptronClassificationModel
> -----------------------------------------------------------------------
>
> Key: SPARK-12664
> URL: https://issues.apache.org/jira/browse/SPARK-12664
> Project: Spark
> Issue Type: Improvement
> Components: ML
> Reporter: Robert Dodier
> Assignee: Weichen Xu
>
> In
> org.apache.spark.ml.classification.MultilayerPerceptronClassificationModel,
> there isn't any way to get raw prediction scores; only an integer output
> (from 0 to #classes - 1) is available via the `predict` method.
> `mplModel.predict` is called within the class to get the raw score, but
> `mlpModel` is private so that isn't available to outside callers.
> The raw score is useful when the user wants to interpret the classifier
> output as a probability.
