WebMar 13, 2024 · GCN、GraphSage、GAT都是图神经网络中常用的模型，它们的区别主要在于图卷积层的设计和特征聚合方式。GCN使用的是固定的邻居聚合方式，GraphSage使用的是采样邻居并聚合的方式，而GAT则是使用了注意力机制来聚合邻居节点的特征。 WebThis tutorial formulates the link prediction problem as a binary classification problem as follows: Treat the edges in the graph as positive examples. Sample a number of non-existent edges (i.e. node pairs with no edges between them) as negative examples. Divide the positive examples and negative examples into a training set and a test set. WebOct 14, 2024 · 1. The difference between edge_weight and edge_attr is that edge_weight is the non-binary representation of the edge connecting two nodes, without edge_weight the edge connecting two nodes either exists or it doesn't (0 or 1) but with the weight the edge connecting the nodes can have arbitrary value. Whereas edge_attr means the features … chuck bush construction
