-------------------------------------
Summary: 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, MLlib
Reporter: Robert Dodier
Priority: Minor
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.
