Decision Trees and Machine Learning for Cookie Monster

Avi Bryant of Stripe is the Author of Brushfire, an extremely scalable framework for distributed and supervised learning of decision tree ensembles in Scala.

This talk, featuring cookie monster, covers the architecture and algorithm of Brushfire where Bryant also runs through examples of using it with Scala library Scalding to build trees on Hadoop.

Also, for context, one of the inspirations for Bryant’s work here was a Google paper on PLANET which talks about a specific way of using MapReduce to learn decision trees.
