---------------------------------------------------------------
[~mengxr] Sorry for the delay. I wrote up a design proposal for the initial
implementation. Let me know what you think, and if you'd like me to clarify
anything.
UPDATE: Ok, here's the document:

UPDATE: On second thought, I'd actually like to make a few changes to the
proposal. I'll follow up tomorrow with the updated version. Sorry for the
confusion.
> Implement Nesterov's accelerated first-order method

> Key: SPARK-1503
> URL: https://issues.apache.org/jira/browse/SPARK-1503
> Project: Spark
> Issue Type: New Feature
> Components: MLlib
> Reporter: Xiangrui Meng
> Assignee: Aaron Staple
>
> Nesterov's accelerated first-order method is a drop-in replacement for
> steepest descent but it converges much faster. We should implement this
> method and compare its performance with existing algorithms, including SGD
> and L-BFGS.
> TFOCS (http://cvxr.com/tfocs/) is a reference implementation of Nesterov's
> method and its variants on composite objectives.
