Modified Gradient Boosting in High-dimensional Nonlinear Regression
Abstract/Contents
- Abstract
- Herein we develop a modification of Freund and Schapire's (1997) AdaBoost algorithm for classification trees and Friedman's (2001) gradient boosting generalization. Not only does this modification address long-standing unresolved problems concerning convergence and when to terminate the iterative algorithms, but it is also shown to have optimality properties via attainment of the convergence rates of oracle benchmarks that are computationally infeasible. Simulation studies are presented to illustrate the key ideas underlying modified gradient boosting and how it works.
