Ajay Saini updated SPARK-21027:
-------------------------------
Description: Adding a class called ParOneVsRest that includes support for a
parallelism parameter in a one vs. rest implementation. A parallel one vs. rest
implementation gives up to a 2X speedup when tested on a dataset with 181024
points. A ticket for the Scala implementation of this classifier is here:
