针对图结构数据,本文提出了一种GAT(graph attention networks)网络。该网络使用masked self-attention层解决了之前基于图卷积(或其近似)的模型所存在的问题。在GAT中,图中的每个节点可以根据邻节点的特征,为其分配不同的权值。GAT的另一个优点在于,无需使用预先构建好的图。因此,GAT可以解决一些基于谱的图神经网络中所

This example shows how to classify graphs that have multiple independent labels using graph attention networks (GATs). If the observations in your data have a graph structure with multiple independent labels, you can use a GAT [1] to predict labels for observations with unknown labels. Using th...
