Function-Space Diffusion for Motion Planning
Zinuo Chang, Yipu Chen, Byoungwoo Park +2
Diffusion-based motion planners have demonstrated strong performance in generating diverse and high-quality robot trajectories in cluttered environments with multiple feasible solu…
PISTO: Proximal Inference for Stochastic Trajectory Optimization
Hongzhe Yu, Zinuo Chang, Yongxin Chen
Stochastic trajectory optimization methods like STOMP enable planning with non-differentiable costs, offering substantial flexibility over gradient-based approaches. We show that S…
Concentration of Stochastic System Trajectories with Time-varying Contraction Conditions
Zishun Liu, Liqian Ma, Hongzhe Yu +1
We establish two concentration inequalities for nonlinear stochastic system under time-varying contraction conditions. The key to our approach is an energy function termed Averaged…
Path Integral Particle Filtering for Hybrid Systems via Saltation Matrices
Karthik Shaji, Sreeranj Jayadevan, Bo Yuan +2
State estimation for hybrid systems that undergo intermittent contact with their environments, such as extraplanetary robots and satellites undergoing docking operations, is diffic…
Safety Verification of Stochastic Systems under Signal Temporal Logic Specifications
Liqian Ma, Zishun Liu, Hongzhe Yu +1
We study the verification problem of stochastic systems under signal temporal logic (STL) specifications. We propose a novel approach that enables the verification of the probabili…
Efficient Iterative Proximal Variational Inference Motion Planning
Zinuo Chang, Hongzhe Yu, Patricio Vela +1
We cast motion planning under uncertainty as a stochastic optimal control problem, where the optimal posterior distribution has an explicit form. To approximate this posterior, thi…
