muSync-GS: Physics-Synchronized Driving Video Synthesis for Weather and Geometric Road Hazards
Yang Chen, Yicheng Zhu, Tao Li +1
High-quality driving data are essential for autonomous-driving systems and generative world models. However, rare and safety-critical scenarios involving adverse weather, braking u…
SceneFactory: GPU-Accelerated Multi-Agent Driving Simulation with Physics-Based Vehicle Dynamics
Yicheng Zhu, Yang Chen, Tao Li +1
Autonomous-driving simulators typically trade physical fidelity for scalable parallelism. Physics-based platforms such as CARLA and MetaDrive provide articulated vehicle dynamics a…
Graphon Particle Systems, Part II: Dynamics of Distributed Stochastic Continuum Optimization
Yan Chen, Tao Li, Xiaofeng Zong
We study the distributed optimization problem over a graphon with a continuum of nodes, which is regarded as the limit of the distributed networked optimization as the number of no…
Graphon Particle Systems, Part I: Spatio-Temporal Approximation and Law of Large Numbers
Yan Chen, Tao Li, Xiaofeng Zong
We study a class of graphon particle systems with time-varying random coefficients. In a graphon particle system, the interactions among particles are characterized by the coupled…
