Alexander Ulanov commented on SPARK-5256: ----------------------------------------- Also, asynchronous gradient update might be a good thing to have. > Improving MLlib optimization APIs > --------------------------------- > > Key: SPARK-5256 > URL: https://issues.apache.org/jira/browse/SPARK-5256 > Project: Spark > Issue Type: Umbrella > Components: MLlib > Affects Versions: 1.2.0 > Reporter: Joseph K. Bradley > > *Goal*: Improve APIs for optimization > *Motivation*: There have been several disjoint mentions of improving the > optimization APIs to make them more pluggable, extensible, etc. This JIRA is > a place to discuss what API changes are necessary for the long term, and to > provide links to other relevant JIRAs. > Eventually, I hope this leads to a design doc outlining: > * current issues > * requirements such as supporting many types of objective functions, > optimization algorithms, and parameters to those algorithms > * ideal API > * breakdown of smaller JIRAs needed to achieve that API > I will soon create an initial design doc, and I will try to watch this JIRA > and include ideas from JIRA comments. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
