[jira] [Created] (SPARK-7495) Improve ML attribute documentation

Joseph K. Bradley created SPARK-7495:
----------------------------------------

             Summary: Improve ML attribute documentation
                 Key: SPARK-7495
                 URL: https://issues.apache.org/jira/browse/SPARK-7495
             Project: Spark
          Issue Type: Documentation
          Components: Documentation, ML
            Reporter: Joseph K. Bradley
            Priority: Minor


ML attribute documentation is currently minimal.  This has led to confusion in some Spark PRs about how to use them.

We should add:
* Scala doc
* examples in the programming guide

The docs should make at least these items clear:
* What the different attribute types are
* How an attribute and attribute group differ
* Example usage creating, modifying, and reading attributes
* Explanation that missing attributes are OK and can be computed/added lazily
