Adaptive Depth in Heterogeneous GNNs: Latency and Memory Trade-offs on Large-Scale Graphs

Abstract

Abstract: This report synthesises findings from 12 peer-reviewed papers addressing the following research question: How do adaptive depth techniques in heterogeneous GNNs compare to static-depth baselines in terms of inference latency and memory footprint on large-scale datasets like Reddit. 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. 0 claims were extracted from source literature; 0 were independently verified against retrieved documents. An automated multi-reviewer quality assessment produced a score of 4.3/10. This report is a machine-generated literature synthesis and does not constitute original research.
