This paper presents our empirical study on the state-of-the-art multi-class imbalanced learning algorithms which are based on One-versus-One (OVO) decomposition. We implemented six algorithms in literature, including SMOTEBagging, UnderBagging, OVO plus OVA, OVO plus SMOTE, One-Against-Higher-...

The proposed method combines a one-versus-one (OVO) decomposition of class pairs and a spectral clustering technique. This method first decomposes a multiclass dataset into several binary-class datasets. Then, it uses spectral clustering to divide the minority classes of binary-class subsets into ...
One-versus-One (OVO) decomposition strategy is a common and useful technique used to address multi-class classification problems, which consists in dividing the original multi-class problem into all binary class sub-problems. The effort to reduce the effect of non-competent classifiers has proven ...
