Summary: Use faster converging optimization method in MLlib
Key: SPARK-6346
URL: https://issues.apache.org/jira/browse/SPARK-6346
Project: Spark
Issue Type: Improvement
Components: ML, MLlib
Reporter: Reza Zadeh
According to experiments in SPARK-1503, the LBFGS algorithm converges much
faster than our current proximal gradient, which is used throughout MLlib. This
ticket is to track replacing slower-converging algorithms, with faster
components e.g. LBFGS
