[jira] [Updated] (SPARK-6884) random forest predict probabilities functionality (like in sklearn)
[ https://issues.apache.org/jira/browse/SPARK-6884?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Joseph K. Bradley updated SPARK-6884: - Affects Version/s: (was: 1.4.0) 1.3.0 random forest predict probabilities functionality (like in sklearn) --- Key: SPARK-6884 URL: https://issues.apache.org/jira/browse/SPARK-6884 Project: Spark Issue Type: New Feature Components: MLlib Affects Versions: 1.3.0 Environment: cross-platform Reporter: Max Kaznady Labels: prediction, probability, randomforest, tree Original Estimate: 72h Remaining Estimate: 72h Currently, there is no way to extract the class probabilities from the RandomForest classifier. I implemented a probability predictor by counting votes from individual trees and adding up their votes for 1 and then dividing by the total number of votes. I opened this ticked to keep track of changes. Will update once I push my code to master. -- 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
