Researchers have introduced HeteGCD, a novel approach for generalized category discovery on heterophilous graphs. This method addresses the challenge of recognizing known classes and discovering new ones in graphs where connected nodes often have dissimilar attributes or belong to different classes. HeteGCD utilizes statistics-aware dual-prototype learning, examining both local attribute differences and neighborhood class distributions to extract discriminative information. The system employs a gated dual-stream encoder for learning node representations and a dual-prototype classifier for category discovery, demonstrating competitive performance against existing methods on heterophilous graph datasets.
