The Foundation: Riemannian Geometry & Graph Challenges
The paper grounds its approach in Riemannian geometry, a mathematical framework ideal for structural analysis of non-Euclidean data like graphs. Unlike Euclidean spaces, graphs exhibit complex structures that vary in curvature, such as hierarchical (negative curvature, like hyperbolic space) and cyclical (positive curvature, like hyperspherical space).
Existing Graph Neural Networks (GNNs) often use Euclidean backbones, limiting their expressiveness for diverse graph topologies. Large Language Models (LLMs) adapted for graphs typically deconstruct structural regularity, losing crucial information. The K-Stereographical model is introduced to unify these diverse curvature spaces into a single analytical framework, addressing the inherent structural complexity and diversity of real-world graphs.
CRGFM: Curvature-Guided Riemannian Graph Foundation Model
CRGFM is a novel GFM designed to overcome limitations by integrating Riemannian geometry. Its architecture includes:
- Mixture of Geometric Experts (MoGE): Describes input graphs using K-stereographical models, each tuned to different curvatures, and a gating network for node-wise expert assignment, minimizing embedding distortion.
- Geometric Standardization: A crucial phase where diverse product manifolds are mapped into a unified latent space (a product bundle of hyperbolic and hyperspherical tangent bundles) using an Augmented Lorentz Transformation (ALT), ensuring geometric consistency.
- Riemannian Graph Transformer: Models structural complexity within the standardized product bundle. It employs cross-geometry attention for structural encoding and parallel transport for disentangled attribute encoding.
- Geometric Self-Supervised Learning: Uses contrastive learning across hyperbolic and hyperspherical geometric views, enabling robust pre-training without explicit data augmentation.
- Riemannian Prompt Learning: Bridges the pre-trained model and downstream tasks by introducing parameterized displacements on the manifold to perturb geometric distributions.
Empirical Evidence: Superior Performance & Transferability
Extensive experiments on diverse real-world graphs demonstrate CRGFM's superiority:
- Cross-Domain Transfer Learning: Outperforms traditional GNNs (GCN, GraphSAGE), self-supervised methods (DGI, GraphMAE2), and other GFMs (GCOPE, OFA, LLaGA, RiemannianGFM) in node classification and link prediction tasks. This highlights its ability to generalize across different graph types, including non-attributed graphs.
- Few-Shot Learning: Shows significant advantages in 1-shot and 5-shot learning settings, proving robust knowledge transfer and generalization even with limited labeled data.
- Impact of Pre-training Data: Performance improves with the number of pre-training datasets and benefits from higher domain similarity between pre-training and target tasks, confirming the foundation model's universality.
- Ablation Studies: Key components like MoGE, Augmented Lorentz Transformation (ALT), cross-geometry attention, and curvature-based contrastive learning are all critical for CRGFM's performance, validating their design choices.
- Clustering & Visualization: Embeddings generated by CRGFM exhibit superior class separability and more well-isolated clusters, resolving geometric entanglement common in other models.
