本质上self attention可以认为是GCN的一种特例，特殊在：1) Edge weight来源于node feature similarity 2...
GCN中的Message从节点的邻居节点传播来,Self-attention的Message从Query的Key-Value传播来。如果称所有的Message Passing函数都是GCN的话,那么Self-attention也就是GCN作用Query和Key-Value所构成Complete Garph上的一种特例。也正如乃岩 @Na...
Graph Attention Networks 是发表在 ICLR 2018 的一项工作,本文作者提出了一种新的 GNN 模型: GAT(Graph Attention Netowrks)。 受到NLP 领域各种 self-attention 模型的启发,作者将其用到了 GNN 网络中,说起来也很简单,就是在学习节点向量时,借助 self-attention 为邻居节点赋予权重。 本文的开源代码地址(tensorfl...
IEEE TIP | SelfGCN:用于基于骨架的动作识别的自注意力图卷积网络 该论文发表于 IEEE Transactions on Image Processing 2024(CCF A类),题目为《SelfGCN: Graph Convolution Network with Self-Attention for Skeleton-Based Action Recognition》。 合肥大学的吴志泽副教授为论文的第一作者,合肥大学的汤卫思教授为本文...
To address the challenge of spatial-temporal correlation in traffic flow forecasting, we propose a novel deep learning model, the multi-head self-attention spatiotemporal graph convolutional network (MSASGCN). It can learn the temporal and spatial dependencies of dynamic traffic data and effectively ...
graph structured data has gained much attention in recent years due to its ability to represent the correlation between different traffic flows; In addition, models and algorithms related toGraphConvolutionNeural network (GCN) have been used for malicious traffic detection. However, existing GCN-based...
