WebSep 15, 2024 · Binary classification. A classification case where the label is only one out of two classes. For more information, see the Binary classification section of the Machine learning tasks topic. Calibration. Calibration is the process of mapping a raw score onto a class membership, for binary and multiclass classification. WebNov 29, 2024 · Classification problems that contain multiple classes with an imbalanced data set present a different challenge than binary classification problems. The skewed distribution makes many conventional machine learning algorithms less effective, especially in predicting minority class examples.
