Webmini-batch training only uses part of vertices and edges through sampling method [2], [3]. Distributed mini-batch training is more efficient than distributed full-batch training as it needs much less time to converge on large graphs while maintaining accuracy [5]. In this work, we focus on distributed mini-batch training on GPUs. WebGraphSAGE [11] proposes a neighbor-sampling method to sample a fixed number of neighbors for each node. VRGCN [6] leverages historical activations to restrict the number of sampled nodes ... Mini-batch training significantly accelerates the training process of the layer-wise sampling method. However, the training time complexity is still ...

WebAs such, batch holds a total of 28,187 nodes involved for computing the embeddings of 128 “paper” nodes. Sampled nodes are always sorted based on the order in which they were sampled. Thus, the first batch['paper'].batch_size nodes represent the set of original mini-batch nodes, making it easy to obtain the final output embeddings via slicing.
