ASPECT: Node-Level Adaptive Spectral Fusion for Graph Contrastive Learning

Researchers introduce ASPECT, a novel spectral graph contrastive learning method that adaptively fuses low- and high-frequency graph signals at the node level rather than uniformly across entire graphs. The approach demonstrates improved representation quality on both homophilic and heterophilic graph benchmarks, addressing limitations in existing graph-level fusion strategies.

Language Models as Messengers: Enhancing Message Passing in Heterophilic Graph Learning

Researchers propose LEMP4HG, a new language model-enhanced approach for improving graph neural networks on heterophilic graphs where connected nodes have different characteristics. The method leverages language models to better understand semantic relationships between text-attributed nodes, outperforming existing methods while maintaining efficiency through selective message enhancement.
