Long-Horizon Wireless Link Scheduling with State-Augmented Graph Neural Networks

Romina Garcia Camargo, Zhiyang Wang, Navid NaderiAlizadeh, Alejandro Ribeiro

We address optimal link scheduling in large-scale wireless networks. The goal is to schedule transmissions over a time horizon so that to maximize sum rate while ensuring that average rates of each customer attain a minimum rate requirement. To this end, we formulate a constraine…

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…
