图中ht-1表示t-1时刻的隐藏状态, xt表示t时刻的交通信息, rt代表重置门,用于控制先前时刻状态信息的度量; ut为上传门,用于控制上传到下一状态的信息度量; ct为t时刻时储存的信息, ht为t时刻的输出状态;总的来说,GRU通过获取t-1时刻的隐藏状态与当时的交通状态信息得到t时刻的交通信息。
What is a Graph Convolutional Network (GCN)? The majority of GNNs are Graph Convolutional Networks, and it is important to learn about them before jumping into a node classification tutorial. The convolution in GCN is the same as a convolution in convolutional neural networks. It multiplies neu...
