AOSO-LogitBoost: Adaptive one-vs-one LogitBoost for multi-class problem

Sun, Peng; Reid, Mark; Zhou, Jie


This paper presents an improvement to model learning when using multi-class LogitBoost for classification. Motivated by the statistical view, LogitBoost can be seen as additive tree regression. Two important factors in this setting are: 1) coupled classifier output due to a sum-to-zero constraint, and 2) the dense Hessian matrices that arise when computing tree node split gain and node value fittings. In general, this setting is too complicated for a tractable model learning algorithm. However,...[Show more]
