WebGCN:训练是full-batch的,难以扩展到大规模网络,并且收敛较慢;. GAT:参数量比GCN多,也是full-batch训练;只用到1-hop的邻居,没有利用高阶邻居,当利用2阶以上邻居,容易发生过度平滑(over-smoothing);. GraphSAGE:虽然支持mini-batch方式训练,但是训练较慢,固定 ... WebMar 15, 2024 · GCN聚合器:由于GCN论文中的模型是transductive的,GraphSAGE给出了GCN的inductive形式,如公式 (6) 所示,并说明We call this modified mean-based aggregator convolutional since it is a rough, linear approximation of a localized spectral convolution,且其mean是除以的节点的in-degree,这是与MEAN ...
