How to Write a Decision Tree (CART) as an Equation

Learn how to express any CART decision tree mathematically. Writing the equation of a CART tree will help you understand how linear effects, nonlinear effects, and interaction terms are handled in CART. Understanding the equation will also provide insight into advanced machine learning techniques where CART is the foundation such as TreeNet Gradient Boosting, RandomForests, MARS® regression splines, ISLE™ model compression, and RuleLearner™.
