----------------------------------------
Summary: LBFGS should document what convergenceTol means
Key: SPARK-6336
URL: https://issues.apache.org/jira/browse/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.
