Web数据导入和预处理. GAT源码中数据导入和预处理几乎和GCN的源码是一毛一样的，可以见 brokenstring：GCN原理+源码+调用dgl库实现中的解读。. 唯一的区别就是GAT的源码把稀疏特征的归一化和邻接矩阵归一化分开了，如下图所示。. 其实，也不是那么有必要区 … WebEach graph attention layer gets node embeddings as inputs and outputs transformed embeddings. The node embeddings pay attention to the embeddings of other nodes it's …
