MODEL-BASED DIFFUSION SAMPLING FOR PREDICTIVE CONTROL IN OFFLINE DECISION MAKING
Offline decision-making demands reliable behaviors from fixed datasets, but existing generative methods often produce dynamically infeasible trajectories. MPDiffuser offers a groundbreaking compositional framework that synergizes a planner, a dynamics model, and a ranker. Using alternating diffusion sampling, it generates diverse, task-aligned, and dynamically feasible trajectories. This approach significantly enhances data fidelity and dynamics consistency, leading to consistent performance gains across D4RL and DSRL benchmarks, with demonstrated scalability to vision-based control and real-world robotic deployment.
