Reading the Sky to Forecast the Ground: Physics-Informed Link-State Forecasting for LEO Networks at Any Location
Yunxiang Chi, Zhenlin An, Longfei Shangguan +1
In this paper, we introduce Gnomon, a physics-informed system that forecasts user-perceived low-Earth-orbit (LEO) downlink throughput, uplink throughput, and round-trip time (RTT)…
Taming Vision Priors for Data Efficient mmWave Channel Modeling
Zhenlin An, Longfei Shangguan, John Kaewell +5
Accurately modeling millimeter-wave (mmWave) propagation is essential for real-time AR and autonomous systems. Differentiable ray tracing offers a physics-grounded solution but sti…
Accelerating Physical Property Reasoning for Augmented Visual Cognition
Hongbo Lan, Zhenlin An, Haoyu Li +2
This paper introduces \sysname, a system that accelerates vision-guided physical property reasoning to enable augmented visual cognition. \sysname minimizes the run-time latency of…
