dc.description.abstract As the ever-increasing fanfare around machine learning grows, so do the seemingly endless number of methods. Without a good grasp of the statistical fundamentals, there is a tendency to think this class of models is a black box that functions as the “magic bullet,” able to blindly solve data problems in every situation. Taking time to examine the underlying principles, and break down how they steer certain model behaviors in the presence of a particular data set, helps to understand how a model will perform and why. Motivated by this mind set, the analytical approach of this paper aims to explore a novel modification to the classic decision tree model that incorporates a two-step-look-ahead approach. Included is a comparative analysis between the original algorithm (one-step-look-ahead logic) and the new one, which shows in the case of a particular simulated dataset that the two-step-look-ahead logic vastly outperforms the classic decision tree algorithm.
