Graphsage mini-batch
Webbased on mini-batch of nodes, which only aggregate the embeddings of a sampled subset of neighbors of each node in the mini-batch. Among them, one direction is to use a node-wise neighbor-sampling method. For example, GraphSAGE [9] calculates each node embedding by leveraging only a fixed number of uniformly sampled neighbors.

WebApr 25, 2024 · Introduce a new architecture called Graph Isomorphism Network (GIN), designed by Xu et al. in 2024. We'll detail the advantages of GIN in terms of discriminative power compared to a GCN or GraphSAGE, and its connection to the Weisfeiler-Lehman test. Beyond its powerful aggregator, GIN brings exciting takeaways about GNNs in …
WebThe first argument g is the original graph to sample from while the second argument indices is the indices of the current mini-batch – it generally could be anything depending on what indices are given to the accompanied DataLoader but are typically seed node or seed edge IDs. The function returns the mini-batch of samples for the current iteration.
