>                 Key: SPARK-18303
>                 URL: https://issues.apache.org/jira/browse/SPARK-18303
>             Project: Spark
>          Issue Type: Umbrella
>          Components: MLlib
>            Reporter: Iskender Unlu

> *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.
