  • 通过多维边特征矩阵构建多通道滤波器,联合学习节点与边信息

  • 适合需要精细结构感知的图学习任务,如社交网络分析

图神经网络(GNN)在处理非欧几里得数据方面具有显著优势,近年来广泛应用并受到广泛关注。现有GNN框架通常将节点与边分别视为信息实体与传播通道,但在信息传播和聚合阶段,节点与边特征的学习常被独立处理,导致二者信息脱节。为此,本文提出边缘增强的图特征偏好学习框架(EdgeGFL),旨在通过学习多维边特征矩阵来辅助节点嵌入。利用该边特征矩阵构建多通道滤波器,更有效地捕捉精确的节点特征,从而获得非局部结构特性和细粒度高阶节点特征。引入关系表示学习到消息传递机制中,使节点能接收更丰富的信息,促进节点表征学习。在4个真实世界异构图上的实验表明,所提模型有效提升了节点表示性能。

原文摘要 · Abstract (English)

Graph Neural Networks (GNNs) have significant advantages in handling non-Euclidean data and have been widely applied across various areas, thus receiving increasing attention in recent years. The framework of GNN models mainly includes the information propagation phase and the aggregation phase, treating nodes and edges as information entities and propagation channels, respectively. However, most existing GNN models face the challenge of disconnection between node and edge feature information, as these models typically treat the learning of edge and node features as independent tasks. To address this limitation, we aim to develop an edge-empowered graph feature preference learning framework that can capture edge embeddings to assist node embeddings. By leveraging the learned multidimensional edge feature matrix, we construct multi-channel filters to more effectively capture accurate node features, thereby obtaining the non-local structural characteristics and fine-grained high-order node features. Specifically, the inclusion of multidimensional edge information enhances the functionality and flexibility of the GNN model, enabling it to handle complex and diverse graph data more effectively. Additionally, integrating relational representation learning into the message passing framework allows graph nodes to receive more useful information, thereby facilitating node representation learning. Finally, experiments on four real-world heterogeneous graphs demonstrate the effectiveness of theproposed model.
