Disentangled Hypergraph Network with Implicit Structure Learning for Mobility Social Relationship Inference

A DHISL network that first captures individual spatiotemporal characteristics through feature-guided representation initialization, and then adopts a dual-branch framework that introduces dual constraints in a multi-channel disentangled space to achieve intra-channel consistency and inter-channel exclusivity.
