图神经网络(GraphNeuralNetworks,GNNs)的引入,为推荐系统提供了一种新的视角,它能够处理复杂的关系结构,如用户之间的社交网络、物品之间的关联网络等,从而更准确地捕捉用户偏好和物品特性。 1.3异构图神经网络的概念 异构图神经网络(HeterogeneousGraphNeuralNetworks,HGNNs)是图神经网络的一个分支,专门用于处理包含多种...
Heterogeneous graphs (HGs) also called heterogeneous information networks (HINs) have become ubiquitous in real-world scenarios. Recently, employing graph neural networks (GNNs) to heterogeneous graphs, known as heterogeneous graph neural networks (HGNNs) which aim to learn embedding in low-dimensional...
1.2 Graph Neural Networks Definition : General GNN Framework: Suppose H^l[t] is the node representation of node t at the (l)-th GNN layer, the update procedure from the (l-1)-th layer to the (l)-th layer is: H^l[t] \leftarrow \underset{\forall s\in N(t),\ \forall e\in...
摘要: Heterogeneous graph learning aims to capture complex relationships and diverse relational semantics among entities in a heterogeneous graph to obtain meaningful representations for nodes and edges. Recent advancements in heterogeneous graphneural networks(HGNNs) have achievedstate-of-the-artperformance ...
近几年异质图GNN(Heterogeneous graph neural networks (HGNNs))颇受关注,但是由于每个工作的数据预处理方式和评估设置都不同,因此很难对新模型具体的进步程度做全面理解。 本文使用12个异质图GNN模型的官方代码、数据集、实验设置和超参,证明了它们毫无进展(也不完全,只能说基本没有)。
1 Sep 2022·Nan Wu,Chaofan Wang· Heterogeneous graph neural networks (HGNNs) have attracted increasing research interest in recent three years. Most existing HGNNs fall into two classes. One class is meta-path-based HGNNs which either require domain knowledge to handcraft meta-paths or consume...
Heterogeneous Graph Neural Networks (HGNNs) have also received great attention in recent years [8], [9], [10]. Similar to their homogeneous counterparts, HGNNs employ a message-passing framework for generating node embeddings. This framework can be categorized into two categories, i.e., meta-...
