Provably Convergent Subgraph-wise Sampling for Fast GNN Training

no code implementations17 Mar 2023 Jie Wang, Zhihao Shi, Xize Liang, Shuiwang Ji, Bin Li, Feng Wu

During the message passing (MP) in GNNs, subgraph-wise sampling methods discard messages outside the mini-batches in backward passes to avoid the well-known neighbor explosion problem, i. e., the exponentially increasing dependencies of nodes with the number of MP iterations.

LMC: Fast Training of GNNs via Subgraph Sampling with Provable Convergence

1 code implementation2 Feb 2023 Zhihao Shi, Xize Liang, Jie Wang

The key idea of LMC is to retrieve the discarded messages in backward passes based on a message passing formulation of backward passes.
