This repository contains the tutorial material for the Gradient Boosted Regression Trees in scikit-learn tutorial at PyData 2014.

Requirements

This tutorial requires scikit-learn 0.14+. I strongly recommend that you update to the current master version (to be 0.15) since it includes a significant speedup for our tree ensembles including Gradient Boosted Regression Trees. You might get slightly different results (Cal-housing scores & variable importances) depending on your version of scikit-learn.
