WebA implementação usa a classe MessagePassing do PyTorch Geometric para passar mensagens (ou informações) entre os nós e a classe degree do PyTorch Geometric para calcular o grau dos nós (ou o número de conexões). Define a classe Net que implementa uma rede neural com duas camadas GCN e uma camada de saída com ativação log … WebThe graph classification can be proceeded as follows: From a batch of graphs, we first perform message passing/graph convolution for nodes to “communicate” with others. After message passing, we compute a tensor for graph representation from node (and edge) attributes. This step may be called “readout/aggregation” interchangeably.
