Subject [jira] [Created] (SPARK-6336) LBFGS should document what convergenceTol means
Date Sat, 14 Mar 2015 17:24:38 GMT
Joseph K. Bradley created SPARK-6336:

             Summary: LBFGS should document what convergenceTol means
                 Key: SPARK-6336
             Project: Spark
          Issue Type: Documentation
          Components: Documentation, MLlib
    Affects Versions: 1.3.0
            Reporter: Joseph K. Bradley
            Priority: Trivial

LBFGS uses Breeze's LBFGS, which uses relative convergence tolerance.  We should document
that convergenceTol is relative and ensure in a unit test that this behavior does not change
in Breeze without us realizing it.
