- Imbalanced Classification In Machine Learning
1 week ago The number of examples that belong to each class may be referred to as the class distribution. Imbalanced classification refers to a classification predictive modeling problem where the number of examples in the training dataset for each class label is not balanced. That is, where the class distribution is not … See more
