Sean Owen updated SPARK-22331:
------------------------------
Summary: Make MLlib string params case-insensitive (was: Strength
consistency for supporting string params: case-insensitive or not)
It would mean accepting some parameters like "regparam" where "regParam" was
required before, but the latter continues to work. It wouldn't break things,
though would cause some code to work that didn't before. Consistency is
probably worthwhile here, if we can make it all consistent in one go.
> Make MLlib string params case-insensitive
> -----------------------------------------
>
> Key: SPARK-22331
> URL: https://issues.apache.org/jira/browse/SPARK-22331
> Project: Spark
> Issue Type: Improvement
> Components: MLlib
> Affects Versions: 2.2.0
> Reporter: yuhao yang
> Priority: Minor
>
> Some String params in ML are still case-sensitive, as they are checked by
> ParamValidators.inArray.
> For consistency in user experience, there should be some general guideline in
> whether String params in Spark MLlib are case-insensitive or not.
> I'm leaning towards making all String params case-insensitive where possible.
