----------------------------------------
Summary: Add compressed support for multinomial logistic
regression coefficients
Key: SPARK-17137
URL: https://issues.apache.org/jira/browse/SPARK-17137
Project: Spark
Issue Type: Sub-task
Components: ML
Reporter: Seth Hendrickson
Priority: Minor
For sparse coefficients in MLOR, such as when high L1 regularization, it may be
more efficient to store coefficients in compressed format. We can add this
option to MLOR and perhaps to do some performance tests to verify improvements.
