Joseph K. Bradley commented on SPARK-4638:
------------------------------------------

Commenting here b/c of the recent dev list thread: Non-linear kernels for SVMs 
in Spark would be great to have.  The main barriers are:
* Kernelized SVM training is hard to distribute.  Naive methods require a lot 
of communication.  To get this feature into Spark, we'd need to do proper 
background research and write up a good design.
* Other ML algorithms are arguably more in demand and still need improvements 
(as of the date of this comment).  Tree ensembles are first-and-foremost in my 
mind.

> Spark's MLlib SVM classification to include Kernels like Gaussian / (RBF) to 
> find non linear boundaries
