A Graph Foundation Model for Wireless Resource Allocation (GFM-RA) learns unified, transferable representations of wireless interference networks through an interference-aware Transformer and a hybrid self-supervised pre-training strategy. This model achieves rapid, sample-efficient adaptation to diverse resource allocation tasks, demonstrating competitive or superior performance against existing baselines even with incomplete channel state information.
Key insights
- Injecting physical interference information directly into the Transformer's attention mechanism (via a bias projector) allows for effective, physically-aware global reasoning about network interference.
- A hybrid pre-training approach, combining generative masked edge prediction and contrastive Teacher-Student learning, effectively captures both local interference correlations and global representation robustness, leading to high sample efficiency.
- The foundation model paradigm enables learning transferable representations of wireless interference networks, allowing rapid and efficient adaptation to diverse resource allocation objectives and out-of-distribution scenarios with minimal fine-tuning data.
