Memory Efficiency and Prediction Performance Trade-offs in Graph Neural Networks on OGB-Mag

Abstract

Abstract: This report synthesises findings from 14 peer-reviewed papers addressing the following research question: What is the trade-off between memory efficiency and prediction performance for different batch sizes in Graph Neural Networks trained with joint structure-label objectives on the large-scale OGB-mag. Heterogeneous graph neural networks (HGNNs) were proposed for representation learning on structural data with multiple types of nodes and edges. To deal with the performance degradation issue when HGNNs become deep, researchers combine metapaths into HGNNs to associate nodes. 9 claims were extracted from source literature; 0 were independently verified against retrieved documents. An automated multi-reviewer quality assessment produced a score of 2.7/10. This report is a machine-generated literature synthesis and does not constitute original research.
