Addressing Aggregation-Induced Information Loss in Graph Neural Networks
Our analysis reveals a critical 'aggregation collapse' bottleneck in GNNs, leading to significant information loss. Our innovative IP-GNN framework mitigates this through non-linear feature transformation, distribution re-scaling, and post-aggregation structural encoding, demonstrating enhanced performance and scalability.

Performance & Scalability
This research critically evaluates limitations in current GNN message-passing paradigms, specifically focusing on how aggregation leads to information loss. It proposes architectural enhancements that can be integrated into existing GNN models to improve their robustness and performance.
The paper leverages information theory, specifically mutual information and entropy, to quantify and analyze information loss during the aggregation step in GNNs. This theoretical grounding provides a strong basis for understanding the 'aggregation collapse' phenomenon and designing effective countermeasures.
Empirical evaluations demonstrate that the proposed IP-GNN framework significantly improves performance across various graph learning tasks and scales better with increasing network depth, addressing common issues like over-smoothing and over-squashing.

| Feature | Baseline GNNs | IP-GNN Framework |
|---|---|---|
| Feature Information Loss | High, due to aggregation collapse and value concentration. | Reduced via non-linear mapping and distribution re-scaler. |
| Structural Information Retention | Poor, node degrees obscured during aggregation. | Preserved using post-aggregation structural encoding. |
| Over-smoothing & Over-squashing | Significant issues at deeper layers. | Mitigated, allowing deeper, more discriminative models. |
| Performance | Limited by information bottlenecks. | Significantly improved across various tasks (up to 5.5% avg.). |
| Scalability | Accuracy plateaus/declines with depth. | Maintains accuracy improvements with increasing depth. |
Impact on Molecular Graph Analysis (ZINC, QM9)
Our IP-GNN framework demonstrated superior performance on molecular graph datasets like ZINC and QM9. By preserving crucial feature and structural information during aggregation, we achieved an average MAE reduction of 8-12% compared to baseline GNNs. This enhancement is critical for applications such as drug discovery and material science, where accurate molecular representation directly impacts predictive models for properties and interactions.
