----------------------------------------
Summary: ML prediction abstractions should have defaultEvaluator
fields
Key: SPARK-9961
URL: https://issues.apache.org/jira/browse/SPARK-9961
Project: Spark
Issue Type: New Feature
Components: ML
Reporter: Joseph K. Bradley
Predictor and PredictionModel should have abstract defaultEvaluator methods
which return Evaluators. Subclasses like Regressor, Classifier, etc. should
all provide natural evaluators, set to use the correct input columns and
metrics. Concrete classes may later be modified to
The initial implementation should be marked as DeveloperApi since we may need
to change the defaults later on.
