Class imbalance is characterized by an uneven distribution of classes, resulting in significantly more instances in one class (majority class or negative class) than in the others …
Many real-world classification problems are significantly class-imbalanced to detriment of the class of interest. The standard set of proper evaluation metrics is well-known but the …
