Cross-Layer Attention
TRANS-SLE vs. TRANS-GAT
Scalability & Fairness
Cross-Layer Attention
The core innovation lies in treating each potential edge as a sequence of layer-wise views, then applying cross-layer self-attention. This mechanism allows the models to dynamically weight layers based on their relevance for predicting a target link, effectively filtering noise and amplifying informative signals. This is crucial for understanding complex inter-layer dependencies.
TRANS-SLE vs. TRANS-GAT
We developed two models: TRANS-SLE, a lightweight transformer using static embeddings, and TRANS-GAT, which integrates Graph Attention Networks (GATs) for richer, layer-specific structural learning. TRANS-SLE is efficient for less layered graphs, while TRANS-GAT excels in larger, denser networks due to its adaptive edge representations and joint optimization of GAT and transformer parameters.
Scalability & Fairness
To ensure practicality, we introduced a Union-Set candidate pool to reduce computational cost without losing meaningful pairs. Additionally, leakage-free evaluation protocols (cross-layer and subgraph generalization) ensure the models' ability to generalize to unseen nodes and structures, making them reliable for real-world deployment.
