Apache Spark commented on SPARK-21027: -------------------------------------- User 'ajaysaini725' has created a pull request for this issue: https://github.com/apache/spark/pull/18281 > Parallel One vs. Rest Classifier > -------------------------------- > > Key: SPARK-21027 > URL: https://issues.apache.org/jira/browse/SPARK-21027 > Project: Spark > Issue Type: New Feature > Components: PySpark > Affects Versions: 2.2.0, 2.2.1 > Reporter: Ajay Saini > > Currently, the Scala implementation of OneVsRest allows the user to run a > parallel implementation in which each class is evaluated in a different > thread. This implementation allows up to a 2X speedup as determined by > experiments but is not currently not tunable. Furthermore, the python > implementation of OneVsRest does not parallelize at all. It would be useful > to add a parallel, tunable implementation of OneVsRest to the python library > in order to speed up the algorithm. > A ticket for the Scala implementation of this classifier is here: > https://issues.apache.org/jira/browse/SPARK-21028 -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
