Xiangrui Meng updated SPARK-1503: --------------------------------- Assignee: Aaron Staple (was: Xiangrui Meng) > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
