Latest 50 papers on graph neural networks: Nov. 2, 2025

Graph Neural Networks (GNNs) have rapidly become a cornerstone of modern AI/ML, enabling us to model and reason about complex, interconnected data structures with unprecedented power. From predicting molecular properties to detecting cyber threats, their ability to capture relational information is transforming diverse fields. Yet, as GNNs grow in sophistication and application, new challenges in scalability, fairness, robustness, and theoretical understanding emerge. This blog post dives into a fascinating collection of recent research papers, revealing groundbreaking advancements that address these critical areas, pushing the boundaries of what GNNs can achieve.

The Big Idea(s) & Core Innovations

The collective research highlights a significant push towards robustness, efficiency, and a deeper theoretical understanding of GNNs. For instance, the paper “Robust GNN Watermarking via Implicit Perception of Topological Invariants” by Jipeng Li and Yanning Shen (University of California, Davis/Irvine) introduces InvGNN-WM, a novel watermarking technique that ties GNN ownership to the model’s implicit understanding of graph invariants, offering unprecedented security and resilience against attacks. Complementing this, Sofiane Ennadir et al. from King AI Labs/Microsoft Gaming, in “Enhancing Graph Classification Robustness with Singular Pooling”, propose RS-Pool, a pooling strategy leveraging singular vectors to significantly boost robustness against adversarial attacks in graph classification, which is further reinforced by their work, “If You Want to Be Robust, Be Wary of Initialization”, highlighting the crucial role of weight initialization in adversarial robustness for GNNs.

Scalability for large graphs is tackled head-on by Aditya K. Ranjan et al. (University of Maryland) in “Plexus: Taming Billion-edge Graphs with 3D Parallel Full-graph GNN Training”, introducing a 3D parallel architecture that achieves remarkable speedups for billion-edge graph training. Similarly, “HOPSE: Scalable Higher-Order Positional and Structural Encoder for Combinatorial Representations” by Martin Carrasco et al. from the University of Fribourg, offers a new way to model higher-order interactions with linear complexity, providing up to 7x speedups over traditional message-passing methods. For real-world deployments, the work “Pruning and Quantization Impact on Graph Neural Networks” by Khatoon Khedri et al., shows that pruning can reduce GNN model sizes by up to 50% without significant accuracy loss.

Beyond robustness and efficiency, several papers delve into specialized applications and theoretical foundations. In the realm of fairness, Chuxun Liu et al. (Guilin University of Electronic Technology/University of South Australia) introduce FairMIB in “Learning Fair Graph Representations with Multi-view Information Bottleneck”, a multi-view information bottleneck framework that disentangles and mitigates biases from both node attributes and graph structure. This is echoed by Yuhan Yang et al. (University of Virginia) in “Adaptive Dual Prompting: Hierarchical Debiasing for Fairness-aware Graph Neural Networks”, proposing ADPrompt, which uses dual-level interventions for hierarchical debiasing. For complex dynamic systems, “From Embedding to Control: Representations for Stochastic Multi-Object Systems” by Xiaoyuan Cheng et al. (UCL), introduces Graph Controllable Embeddings (GCE) for efficient control of stochastic multi-object systems, leveraging GNNs for adaptive interaction modeling.
