Joseph K. Bradley created SPARK-3724: ----------------------------------------
Summary: RandomForest: More options for feature subset size Key: SPARK-3724 URL: https://issues.apache.org/jira/browse/SPARK-3724 Project: Spark Issue Type: Improvement Components: MLlib Reporter: Joseph K. Bradley Priority: Minor RandomForest currently supports using a few values for the number of features to sample per node: all, sqrt, log2, etc. It should support any given value (to allow model search). Proposal: If the parameter for specifying the number of features per node is not recognized (as “all”, “sqrt”, etc.), then it will be parsed as a numerical value. The value should be either (a) a real value in [0,1] specifying the fraction of features in each subset or (b) an integer value specifying the number of features in each subset. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
