Scaling Efficiency of Hybrid Graph Neural Networks with Synthetic Augmentation and Contrastive Learning

Abstract

Abstract: This report synthesises findings from 13 peer-reviewed papers addressing the following research question: How does the computational efficiency of hybrid graph neural networks combining synthetic graph augmentation and contrastive learning scale with graph size compared to variational inference. We present a novel edge-level ego-network encoding for learning on graphs that can boost Message Passing Graph Neural Networks (MP-GNNs) by providing additional node and edge features or extending message-passing formats. The proposed encoding is sufficient to distinguish. 11 claims were extracted from source literature; 0 were independently verified against retrieved documents. An automated multi-reviewer quality assessment produced a score of 3.7/10. This report is a machine-generated literature synthesis and does not constitute original research.

Research Question

How does the computational efficiency of hybrid graph neural networks combining synthetic graph augmentation and contrastive learning scale with graph size compared to variational inference baselines, as measured by inference throughput and memory usage on OGBN-MAG and OGBN-Proteins benchmarks?
