Subject: Retrieve best parameters from CrossValidator


Hi everyone,

Is there a better way to retrieve the best model parameters obtained from
cross validation than inspecting the logs issued while calling the fit
method (with the call here:
https://github.com/apache/spark/blob/branch-1.5/mllib/src/main/scala/org/apache/spark/ml/tuning/CrossValidator.scala#L106)?

Wouldn't it be useful to expose this to the end user through the
crossValidatorModel?

Thanks for your response.

Best,
Ben.
