Subject [jira] [Created] (SPARK-5256) Improving MLlib optimization APIs
Date Wed, 14 Jan 2015 23:08:34 GMT
Joseph K. Bradley created SPARK-5256:
----------------------------------------

             Summary: 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.
