A Hybrid Sampling Approach for Imbalanced Binary and Multi-Class Data Using Clustering Analysis
IEEE Access, 2022 Unequal data distribution among different classes usually cause a class imbalance problem. Due to the class imbalance, the classification models become biased toward the majority class and misclassify the minority class.

Work–life balance/imbalance: the dominance of the middle class and the neglect of the working class [PDF]
, 2015 The paper was stimulated by the question of class in work-life debates. The common conclusion from work-life studies is that work-life imbalance is largely a middle class problem.
