Mixture of Experts for Node Classification

open access: yesProceedings of the 2025 International Conference on Multimedia Retrieval
Nodes in the real-world graphs exhibit diverse patterns in numerous aspects, such as degree and homophily. However, most existent node predictors fail to capture a wide range of node patterns or to make predictions based on distinct node patterns, resulting in unsatisfactory classification performance.
