arXiv:2605.22480v1 Announce Type: new Abstract: Mini-batch training of Graph Neural Networks (GNNs) is fundamentally different from training on i.i.d. data: sampling a subgraph alters the topology and introduces boundary effects, leading prior work to develop structure-aware samplers that preserve local connectivity and reduce embedding variance. Surprisingly, we demonstrate that the simplest possible scheme, Random Node Sampling (RNS), training on the induced subgraph of uniformly sampled nodes, matches or outperforms full-graph training on 8 of 10 datasets at a fraction of the wall-clock tim
The continuous drive for more efficient AI training methods, specifically for Graph Neural Networks, leads to ongoing research into optimizing computational resource utilization.
This development suggests a significant leap in the efficiency of GNN training, potentially making complex graph-based AI models more accessible and faster to develop and deploy.
The paradigm for training GNNs may shift towards simpler, yet more effective, sampling techniques, reducing computational overhead and accelerating research and application development.
