Combining weighted SMOTE with ensemble learning for the class-imbalanced prediction of small business credit risk

Abstract In small business credit risk assessment, the default and nondefault classes are highly imbalanced. To overcome this problem, this study proposes an extended ensemble approach rooted in the weighted synthetic minority oversampling technique (WSMOTE), which is called WSMOTE-ensemble. The pro...
