通过调用**torch_geometric.nn.to_hetero()** 或 torch_geometric.nn.to_hetero_with_bases() 来自动地将同质图GNN转换为异质图GNN。 通过PyG提供的用于异质图卷积操作的封装函数 conv.HeteroConv 来为不同类型的节点/边定义各自的卷积函数。 这种方法特别适合对不同类型的边应用不同的消息传递函数的情况。 使用...

Heterogeneous Graph Neural Networks:Heterogeneous GNNs can now easily be created from homogeneous ones viann.to_heteroandnn.to_hetero_with_bases. These processes take an existing GNN model and duplicate their message functions to account for different node and edge types: from torch_geometric.nn impo...

@sophiakrix , the encoder in the movielens example does have a heterogeneous encoder due to this line: self.encoder = to_hetero(self.encoder, data.metadata(), aggr='sum') I think you mainly need to change the decoder and loss function, and think about how you feed in your batches of ...
异构图在PyG内对应的数据类是torch_geometric.data.HeteroData,对于每一个节点/边类型,需要定义其节点特征、edge_index和边特征(对应torch_geometric.data.Data类内的data.x、data.edge_index和data.edge_attr)。例如: from torch_geometric.data import HeteroData data = HeteroData() data['paper'].x = .....

macrostomum to other heterophyids, but the separation of the Heterophyidae and Opisthorchiidae remains unclear. Additionally, we used indirect immunocytochemistry and the phalloidin-fluorescence techniques allied with confocal laser scanning microscopy to describe muscular and neuronal structures of P ....
