DB Tsai created SPARK-7262:
------------------------------
Summary: LogisticRegression with L1/L2 (elastic net) using OWLQN
in new ML package
Key: SPARK-7262
URL: https://issues.apache.org/jira/browse/SPARK-7262
Project: Spark
Issue Type: Bug
Components: ML
Reporter: DB Tsai
1) Handle scaling and addBias internally.
2) L1/L2 elasticnet using OWLQN optimizer.
3) Initial weights should be computed from prior probabilities.
4) Ideally supports multinomial version in this PR. It will depend if ML api
support multi-class classification.
