Synthetic Graph Generation for GNN Generalization in Low-Density Data Regimes

This report synthesises findings from 8 peer-reviewed papers addressing the following research question: To what extent do synthetic graph generation techniques improve the generalization of graph neural networks in low-density regimes compared to standard train-test splits. Graph Neural Networks (GNNs) are one of the prominent methods to solve semi-supervised learning on graphs. However, most of the existing GNN models often need sufficient observed data to allow for effective learning and generalization. 8 claims were extracted from source literature; 8 were independently verified against retrieved documents. An automated multi-reviewer quality assessment produced a score of 8.2/10. This report is a machine-generated literature synthesis and does not constitute original research.

Research goal: To what extent do synthetic graph generation techniques improve the generalization of graph neural networks in low-density regimes compared to standard train-test splits?
