Yanbo Liang commented on SPARK-17136:
-------------------------------------
[~sethah] Thanks for the design doc.
One quick question: In your design, if we set the parameters in optimizer, Do
we still support setting these parameters in estimator again?
If yes, why we need to support two entrances for the same set of params? I saw
you reply at the design doc, you propose to make the params in optimizer
superior to the ones in estimator. Does it involves confusion for users and
extra maintenance cost?
Does the grid search-based model selection in the current framework (such as
CrossValidator) can still work well? Thanks.
