It will depend if ML api support multi-class classification. > Binary 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: New Feature > Components: ML > Reporter: DB Tsai > > 1) Handle scaling and addBias internally. > 2) L1/L2 elasticnet using OWLQN optimizer. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscribe@spark.apache.org For additional commands, e-mail: issues-help@spark.apache.org
