Distilling human mobility models with symbolic regression
Hao Guo, Weiyu Zhang, Junjie Yang +3
Human mobility is a fundamental aspect of social behavior, with broad applications in transportation, urban planning, and epidemic modeling. Represented by the gravity model and th…
Uni-RS: A Spatially Faithful Unified Understanding and Generation Model for Remote Sensing
Weiyu Zhang, Yuan Hu, Yong Li +1
Unified remote sensing multimodal models exhibit a pronounced spatial reversal curse: Although they can accurately recognize and describe object locations in images, they often fai…
A Gravity-informed Spatiotemporal Transformer for Human Activity Intensity Prediction
Yi Wang, Zhenghong Wang, Fan Zhang +9
Human activity intensity prediction is crucial to many location-based services. Despite tremendous progress in modeling dynamics of human activity, most existing methods overlook p…
Percolation transition of k-frequent destinations network for urban mobility
Weiyu Zhang, Furong Jia, Jianying Wang +2
Urban spatial interactions are a complex aggregation of routine visits and random explorations by individuals. The inherent uncertainty of these random visitations poses significan…
Hierarchical accompanying and inhibiting patterns on the spatial arrangement of taxis' local hotspots
Xiao-Jian Chen, Quanhua Dong, Changjiang Xiao +4
The spatial arrangement of taxi hotspots indicates their inherent distribution relationships, reflecting their spatial organization structure, and has received attention in urban s…
