Joseph K. Bradley updated SPARK-7146:
-------------------------------------
Target Version/s: 1.6.0 (was: 1.5.0)
> Should ML sharedParams be a public API?
> ---------------------------------------
>
> Key: SPARK-7146
> URL: https://issues.apache.org/jira/browse/SPARK-7146
> Project: Spark
> Issue Type: Brainstorming
> Components: ML
> Reporter: Joseph K. Bradley
>
> Discussion: Should the Param traits in sharedParams.scala be private?
> Pros:
> * Users have to be careful since parameters can have different meanings for
> different algorithms.
> Cons:
> * Sharing the Param traits helps to encourage standardized Param names and
> documentation.
> * If the shared Params are public, then implementations could test for the
> traits. We probably do not want users to do that.
> Currently, the shared params are public but marked as DeveloperApi.
> Proposal: Either
> (a) make the shared params private to encourage users to write specialized
> documentation and value checks for parameters, or
> (b) design a better way to encourage overriding documentation and parameter
> value checks
