Kernel-based Substructure Exploration for Next POI Recommendation [PDF]
arXiv, 2022 Point-of-Interest (POI) recommendation, which benefits from the proliferation of GPS-enabled devices and location-based social networks (LBSNs), plays an increasingly important role in recommender systems. It aims to provide users with the convenience to discover their interested places to visit based on previous visits and current status.
