The Annals of Statistics 2000, Vol. 28, No. 2, 337–407 SPECIAL INVITED PAPER ADDITIVE LOGISTIC REGRESSION: A STATISTICAL VIEW OF BOOSTING By Jerome Friedman,1 Trevor Hastie2 3 and Robert Tibshirani2 4 Stanford University Boosting is one of the most important recent developments in classi- fication methodology. Boosting works by sequentially applying a classifica- tion algorithm
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

# Exercise 6: Wumpus Where Are You? (30 Marks) In this final exercise we want you to go the extra mile and put together a more interesting application of the algorithms you’ve been implementing in the first exercises. The task is to write a program that takes observations (percepts) gathered by the Wumpus World agent
