Abstract
Logitboost is an influential boosting algorithm for classification. In this paper, we develop ro- bust logitboost to provide an explicit formu- lation of tree-split criterion for building weak learners (regression trees) for logitboost. This formulation leads to a numerically stable im- plementation of logitboost. We then propose abc-logitboost for multi-class classification, by combining robust logitboost with the prior work of abc-boost. Previously, abc-boost was imple- mented as abc-mart using the mart algorithm. Our extensive experiments on multi-class clas- sification compare four algorithms: mart, abc- mart, (robust) logitboost, and abc-logitboost, and demonstrate the superiority of abc-logitboost. Comparisons with other learning methods in- cluding SVM and deep learning are also avail- able through prior publications.
