ABC-Boost: Adaptive Base Class Boost for Multi-Class Classification

ABC-Boost: Adaptive Base Class Boost for Multi-Class Classification

This video was recorded at 26th International Conference on Machine Learning (ICML), Montreal 2009. We propose ABC-Boost (Adaptive Base Class Boost) for multi-class classification and present ABC-MART, an implementation of ABC-Boost. The original MART (Multiple Additive Regression Trees) algorithm has been popular in certain industry applications (e.g., Web search). For binary classification, ABC-MART recovers MART. For multi-class classification, ABC-MART improves MART, as evaluated on several public data sets.
