Researchers have developed Refining Compositional Diffusion (RCD), a new method to improve long-horizon trajectory planning for robots. RCD addresses the issue of mode-averaging in compositional diffusion planning, where combining short-horizon plans can lead to globally incoherent or locally infeasible trajectories. By using a training-free guidance technique that leverages self-reconstruction error and overlap consistency, RCD steers the planning process towards more reliable and coherent paths. Experiments on complex tasks in OGBench, including locomotion and object manipulation, show RCD significantly outperforms existing methods. AI
