提出HONOR框架,统一处理同质与异质超图的表示学习。
Hypergraph Contrastive Learning for both Homophilic and Heterophilic Hypergraphs
- 通过提示词构造与自适应注意力,显式建模超边与节点的异质关系。
- 在同质与异质数据集上均超越现有基线,提升表示鲁棒性。
- 适合需处理复杂高阶关系的图神经网络研究者使用。
超图作为传统图的推广,能自然刻画高阶关系。近年来,超图神经网络(HNNs)被广泛用于捕捉复杂高阶结构。然而,大多数现有方法依赖同质性假设,这在真实世界中常不成立,尤其当存在显著异质结构时。为解决此问题,我们提出 extbf{HONOR},一种适用于同质与异质超图的无监督超图对比学习框架。具体而言,HONOR 通过两种互补机制显式建模超边与节点间的异质关系:基于提示词的超边特征构建策略,在保持全局语义一致性的同时抑制局部噪声;以及自适应注意力聚合模块,动态捕捉节点对超边的多样化局部贡献。结合高通滤波设计,使 HONOR 充分利用异质连接模式,生成更具判别性和鲁棒性的节点与超边表示。理论上,我们证明了 HONOR 具备更优泛化能力与鲁棒性。实证上,大量实验验证其在同质与异质数据集上均持续优于当前最优基线。
原文摘要 · Abstract (English)
Hypergraphs, as a generalization of traditional graphs, naturally capture high-order relationships. In recent years, hypergraph neural networks (HNNs) have been widely used to capture complex high-order relationships. However, most existing hypergraph neural network methods inherently rely on the homophily assumption, which often does not hold in real-world scenarios that exhibit significant heterophilic structures. To address this limitation, we propose \textbf{HONOR}, a novel unsupervised \textbf{H}ypergraph c\textbf{ON}trastive learning framework suitable for both hom\textbf{O}philic and hete\textbf{R}ophilic hypergraphs. Specifically, HONOR explicitly models the heterophilic relationships between hyperedges and nodes through two complementary mechanisms: a prompt-based hyperedge feature construction strategy that maintains global semantic consistency while suppressing local noise, and an adaptive attention aggregation module that dynamically captures the diverse local contributions of nodes to hyperedges. Combined with high-pass filtering, these designs enable HONOR to fully exploit heterophilic connection patterns, yielding more discriminative and robust node and hyperedge representations. Theoretically, we demonstrate the superior generalization ability and robustness of HONOR. Empirically, extensive experiments further validate that HONOR consistently outperforms state-of-the-art baselines under both homophilic and heterophilic datasets.
