16 Ensemble Learning 16.1 Introduction The idea of ensemble learning is to build a prediction model by combining the strengths of a collection of simpler base models. We have already seen a number of examples that fall into this category. Bagging in Section 8.7 and random forests in Chapter 15 are ensemble methods for classification,

10 Boosting and Additive Trees 10.1 Boosting Methods Boosting is one of the most powerful learning ideas introduced in the last twenty years. It was originally designed for classification problems, but as will be seen in this chapter, it can profitably be extended to regression as well. The motivation for boosting was a procedure that

RESEARCH | REPORTS intrinsic and extrinsic contributions depends on the sample quality (such as the doping density and the amount of disorder). Studies of the de- pendence on temperature and on disorder are therefore required to better understand the doping density dependence of the VHE. Furthermore, a more accurate determination of sH that takes into
