Imbalanced features machine learning
WitrynaA. Imbalanced learning Imbalanced learning focuses on how a disparity in the number of class samples affects the training of supervised clas-sifiers. The classes are colloquially referred to as the majority class(es) (with more samples) and the minority class(es) (with fewer samples). The number of majority and minority classes Witryna23 lis 2024 · However, overall accuracy in machine learning classification models can be misleading when the class distribution is imbalanced, and it is critical to predict the minority class correctly. In this case, the class with a higher occurrence may be correctly predicted, leading to a high accuracy score, while the minority class is being …
