Researchers have introduced DyGFM, a novel Dynamic Graph Foundation Model designed to handle data from multiple domains. This model addresses the challenge of inconsistent semantic and temporal patterns across different domains, which often leads to negative knowledge transfer in existing "pretrain-then-finetune" approaches. DyGFM employs a dual-branch pre-training strategy for semantic-temporal decoupling and a cross-domain routing mechanism to mitigate negative transfer during adaptation. Experiments show DyGFM outperforms 12 state-of-the-art baselines on node classification and link prediction tasks. AI
