one-versus-rest和one-versus-one的不同 SVM算法最初是为二值分类问题设计的,当处理多类问题时,就需要构造合适的多类分类器。 目前,构造SVM多类分类器的方法主要有两类:一类是直接法,直接在目标函数上进行修改,将多个分类面的参数求解合并到一个最优化问题中,通过求解该最优化问题“一次性”实现多类分类。这种...

很大程度上减少了支持向量机的训练时间。2 The thesis improves the conventional SVM, and uses several one-versus-one classifiers to construct multi-class classification.本文在传统的SVM上进行改进,采用多个一对一SVM构造多值分类SVM。one
Multi-class learningImbalanced learningOne-versus-one decompositionSMOTEIn supervised learning, the underlying skewed distribution of multiple classes poses extreme difficulties for learning good models. A common scheme to deal with the multi-class imbalanced problem is to decompose an original dataset into...
