Debasish Das commented on SPARK-10078:
--------------------------------------
[~mengxr] [~dlwh] is it possible to implement VL-BFGS as part of breeze so that
OWLQN, LBFGS, LBFGS-B and proximal.NonlinearMinimizer get benefited by it ? We
can bring it the way we bring LBFGS/OWLQN right now...If it makes sense, I can
look at the design doc and propose a breeze interface to abstract RDD details...
