Subject [jira] [Commented] (SPARK-6884) Random forest: predict class probabilities
Date Wed, 29 Jul 2015 13:10:05 GMT


Max Kaznady commented on SPARK-6884:

Sorry, I've been trying to setup a work environment to push the change.

The problem is the security in my workplace - I can't push any code out which I've developed.
So I would have to re-develop from scratch at home and push the change in.

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.
