It relates to distributed consensus, gossip algorithms, and decentralized optimization. Knowledge 'diffusion' resembles gossip protocols, while 'overlap' means intersections in data or tasks among nodes. It integrates these theories to address convergence under heterogeneous, asynchronous, and private conditions. 它关联了分布式共识、gossip 算法和分散式优化。知识的“扩散”类似 gossip 协议,“重叠”指节点间数据或任务的交集。该机制需融合这些理论,解决异构、异步和隐私条件下的模型收敛问题。
