Web当然这些方法也有很大的提升空间，这里提出SAGPool来做基于层级关系的graph pooling语义下的Self-Attention Graph Pooling。. 通过自注意力机制，我们可以知道哪些节点可以保留而哪些节点可以剔除，这样可以更好的层级性表示图的特征。. 文中还介绍了graph pooling的演变 ... WebHowever, in the graph classification tasks, these graph pooling methods are general and the graph classification accuracy still has room to improvement. Therefore, we propose the covariance pooling (CovPooling) to improve the classification accuracy of graph data sets. CovPooling uses node feature correlation to learn hierarchical ...

WebOct 22, 2024 · Graph pooling is a central component of a myriad of graph neural network (GNN) architectures. As an inheritance from traditional CNNs, most approaches formulate graph pooling as a cluster assignment problem, extending the idea of local patches in regular grids to graphs. Despite the wide adherence to this design choice, no work has … church lane betley
