Building on the discussion of individual decision trees in the prior episode, Shea and Anders shift to one of today’s most popular ensemble models, the Random Forest. At first glance, the algorithm may seem like a brute force approach of simply running hundreds or thousands of decision trees, but it leverages the...

Shea and Anders dive into tree-based algorithms, starting with the most fundamental variety, the single decision tree. We cover the mechanics of a decision tree and provide a comparison to linear models. A solid understanding of how a decision tree works is critical to fully grasp the nuances of the more powerful...

This is the first episode in a new mini-series, “Return to Trees”. In this series, Shea and Anders will be covering tree-based algorithms, including single decision trees, Random Forests, and Gradient Boosting Machines. In this episode, we discuss the rationale for re-visiting these models, which were covered in...
