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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
