WebIn this article we propose a boosting algorithm for regression with functional explanatory variables and scalar responses. The algorithm uses decision trees constructed with multiple projections as the"base-learners", which we call"functional multi-index trees". We establish identifiability conditions for these trees and introduce two algorithms to compute them.
