OpFlow: Learning Opportunity-Conditioned Choice Potentials for Robust OD Flow Prediction

Changjian Liu, Yong Gao, Yuqing Wang, Leyi Su, Honglei Guo, Zhiyang Wang, et al.

Origin-destination (OD) flow prediction is central to urban analytics, yet deep models trained on raw counts remain vulnerable to distribution shift. The core problem is that raw count supervision cannot distinguish transferable choice mechanisms from environment-specific shortcu…
