The paper proposes a novel approach to Offline Goal-Conditioned Reinforcement Learning (Offline GCRL), which focuses on learning diverse goal-oriented skills from pre-collected behavior datasets without reward feedback. The authors leverage the conditional diffusion model to generate long-horizon plans for RL, addressing limitations of previous methods. They introduce SSD (Sub-trajectory Stitching with Diffusion), a model-based offline GCRL method that estimates target values from goal-relabeled datasets and generates future plans conditioned on target goals and values. This approach achieves state-of-the-art performance in standard benchmark tasks and demonstrates the ability to stitch suboptimal trajectories into high-quality plans.

This paper is about using artificial intelligence to learn new skills without getting rewarded or punished for each small step. It’s like learning a new language by listening to native speakers, rather than practicing individual words. The researchers use a special type of model that can generate plans for the future based on what we want to achieve. They show that this approach works really well and can even fix mistakes in old data to create better plans.
