VecFormer: Towards Efficient and Generalizable Graph Transformer with Graph Token Attention
Revolutionizing Graph Transformers for Scalable, Generalizable AI in Enterprise.
Executive Impact
VecFormer addresses critical challenges in Graph Transformers: computational complexity (O(N²)) and poor generalization in Out-of-of-Distribution (OOD) scenarios. By introducing a two-stage training paradigm, VecFormer uses vector quantization to learn rich semantic Graph Codes from node features and graph structure. Attention mechanisms are then performed at the Graph Token level, reducing complexity to O(NNfNs) and significantly enhancing generalization, especially in OOD settings. This leads to superior performance and speed across various graph sizes and tasks like node classification, outperforming existing Graph Transformers.

Graph Token Attention
VecFormer achieves linear computational complexity O(N) by reducing attention operations from node-level to Graph Token level, using a context-aware Graph Token List. This allows for scalability to millions of nodes without increasing complexity, significantly outperforming traditional Graph Transformers in speed and resource usage, as demonstrated on large-scale datasets like Ogbn-proteins, Amazon2m, and Pokec.
By employing Graph Token Attention based on pre-trained Graph Codes, VecFormer significantly enhances generalization ability in Out-of-Distribution (OOD) scenarios. It learns diverse attention patterns by dynamically adjusting weight coefficients for Feature and Structure Codes, preventing attention weights from converging to uniform distributions typical in vanilla Transformers. This robust approach leads to substantial performance gains on OOD datasets like Cora and Citeseer.
The core innovation of VecFormer is the Graph Token Attention mechanism. Through a two-stage process, node features and graph structures are compressed into semantically rich Graph Codes using soft vector quantization. These codes are then fused into Graph Tokens, enabling efficient and generalizable attention at a higher abstraction level than individual nodes. This ensures the model captures global graph information while minimizing computational overhead.
