Witryna25 lip 2024 · Imbalanced Data Classification. Most of data in the real-word are imbalance in nature. Imbalanced class distribution is a scenario where the number of observations belonging to one class is significantly lower than those belonging to the other classes. This happens because Machine Learning Algorithms are usually … Witrynastructures throughout the graph, i.e., the majority classes would dominate feature propagation between nodes. In this paper, we focus on a more general setting of multi-class imbalanced graph learning and develop a novel graph convolutional network incorporating two types of regular-ization. To the best of our knowledge, this is the first
