Joseph K. Bradley commented on SPARK-5256:
------------------------------------------
Added link to [SPARK-1227], which discusses ML diagnostics and brings up the
question of what loss functions should be provided as Loss classes rather than
via the ClassificationMetrics and RegressionMetrics classes.
> 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.
