Abstract

Breiman, Friedman, Gordon and Stone recognized that tree classifiers would be very valuable to practicing statisticians. Their cart algorithm became very popular indeed. Designing tree-based classifiers, however, has its pitfalls. It is easy to make them too simple or too complicated so that Bayes risk consistency is compromised. In this talk, we explore the relationship between algorithmic complexity of tree-based methods and performance.
