Hybrid Ray-Tracing and Physics-Embedded Neural Modeling for High-Fidelity Channel Reconstruction in Wireless Digital Twins
Huiwen Zhang, Chu Ma, Feng Ye
Many existing wireless digital twins (DTs) rely heavily on ray-tracing (RT)-based channel simulators to achieve scalability in large-scale environments. However, the geometric-opti…
PE-EK-PINN: Physics Embedding with Evolving Kernel for Scalable Physics-Informed Neural Networks
Huiwen Zhang, Feng Ye, Chu Ma
Physics-Informed Neural Networks (PINNs) embed governing equations into deep learning, but enforce them only through loss residuals, leaving highly oscillatory wave behavior to be…
TG-DIN: Theory-Guided Demand Inference Network for Generalizable QoS Prediction
Fuliang Yang, Feng Ye
Network measurements reveal the service a flow receives, not the load it offers to the network. Predictors trained directly on observed traffic therefore become tied to the operati…
