----------------------------------------
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.
