WebMay 4, 2024 · GraphSAGE was developed by Hamilton, Ying, and Leskovec (2024) and it builds on top of the GCNs . The primary idea of GraphSAGE is to learn useful node embeddings using only a subsample of neighbouring node features, instead of the whole graph. In this way, we don’t learn hard-coded embeddings but instead learn the weights … WebApr 28, 2024 · Visual illustration of the GraphSAGE sample and aggregate approach,图片来源[1] 2.1 采样邻居. GNN模型中，图的信息聚合过程是沿着Graph Edge进行的，GNN中节点在第(k+1)层的特征只与其在(k)层的邻居有关，这种局部性质使得节点在(k)层的特征只与自己的k阶子图有关。
