摘要:

多年来,当不同类型的误分类错误产生不同的成本时,已经提出了大量的成本敏感方法来学习数据。我们的贡献是一个统一的框架,提供了一个全面的和有见地的概述成本敏感的集成方法,通过细粒度的分类,找出它们的差异和相似之处。我们的框架包含了各种方法的自然扩展和概括,无论是AdaBoost,Bagging还是随机森林,因此不仅产生了迄今为止已知的所有方法,而且还产生了一些以前没有考虑过的方法。

英文摘要:

Over the years, a plethora of cost-sensitive methods have been proposed for learning on data when different types of misclassification errors incur different costs. Our contribution is a unifying framework that provides a comprehensive and insightful overview on cost-sensitive ensemble methods, pinpointing their differences and similarities via a fine-grained categorization. Our framework contains natural extensions and generalisations of ideas across methods, be it AdaBoost, Bagging or Random Forest, and as a result not only yields all methods known to date but also some not previously considered.
