Witryna22 paź 2024 · Recent years have witnessed the significant success of applying graph neural networks (GNNs) in learning effective node representations for classification. However, current GNNs are mostly built under the balanced data-splitting, which is inconsistent with many real-world networks where the number of training nodes can … Witryna21 cze 2024 · Recent years have witnessed great success in handling node classification tasks with Graph Neural Networks (GNNs). However, most existing … WitrynaHowever, the nodes in many real-world graphs are inherently class-imbalanced (Mohammadrezaei et al.,2024;Wang et al.,2024a), hence GNNs are prone to be biased toward major classes, as in general class-imbalance tasks. This bias forces networks to poorly classify the nodes of minor classes, resulting in destructive impacts and a large sm400cとは
