Joseph K. Bradley updated SPARK-6884:
-------------------------------------
Summary: Random forest: predict class probabilities (was: random forest
predict probabilities functionality (like in sklearn))
> Random forest: predict class probabilities
> ------------------------------------------
>
> Key: SPARK-6884
> URL: https://issues.apache.org/jira/browse/SPARK-6884
> Project: Spark
> Issue Type: Sub-task
> 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.
