WitrynaExperiments on real-world imbalanced graph data demonstrate that BNE vastly outperforms the state-of-the-art methods for semi-supervised node classification on imbalanced graph data. Introduction In daily life, the graph is a common data structure, and graph data appears in many applications, including social media [36], [8], the … 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
