VOiLA: Vectorized Online Planning with Learned Diffusion Model for POMDP Agents
Researchers have developed VOiLA, a new framework for planning under uncertainty using learned diffusion models for POMDP agents. VOiLA learns task-agnostic POMDP models by employing conditional diffusion models for transition and observation sampling, and particle-based belief updates. The framework distills these diffusion samplers into efficient feedforward generators, integrating them with a GPU-parallelized planner called VOPP. This distillation significantly reduces sampling costs, making learned POMDP models practical for online planning and demonstrating strong performance and generalization capabilities on benchmark problems and physical robot evaluations.
