Graph Neural Networks: Homophily, Not Rarity, Drives Classification Success

A new research paper published on arXiv explores the performance of Graph Neural Networks (GNNs) in classifying nodes within graphs. The study challenges the common assumption that rare nodes are inherently harder to classify due to their rarity, suggesting instead that homophily plays a more significant role. The findings indicate that even rare nodes can be classified effectively if they exhibit homophily, and that information crucial for classifying heterophilic nodes is often recoverable through retraining.
