Julian King commented on SPARK-9478: ------------------------------------ Has there been any progress on this in recent times? It looks like there are multiple pull requests for this but no comments in more than a year.... :( > Add sample weights to Random Forest > ----------------------------------- > > Key: SPARK-9478 > URL: https://issues.apache.org/jira/browse/SPARK-9478 > Project: Spark > Issue Type: Improvement > Components: ML > Affects Versions: 1.4.1 > Reporter: Patrick Crenshaw > Priority: Major > > Currently, this implementation of random forest does not support sample > (instance) weights. Weights are important when there is imbalanced training > data or the evaluation metric of a classifier is imbalanced (e.g. true > positive rate at some false positive threshold). Sample weights generalize > class weights, so this could be used to add class weights later on. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
