WebJun 26, 2012 · An empirical evaluation of four algorithms for multi-class classification: Mart, abc-mart, robust logitboost, and abc-logitboost. Arxiv preprint arXiv:1001.1020, 2010b. Li, P. Fast abc-boost for multi-class classification. Arxiv preprint arXiv:1006.5051, 2010c. WebMay 22, 2024 · In this paper, we develop a unified framework for effectively selecting the base class by introducing a series of ideas to improve the computational efficiency of ABC-Boost. Our framework has parameters ( s, g, w). At each boosting iteration, we only search for the " s -worst classes" (instead of all classes) to determine the base class.
