New Algorithm CARL Enhances Skill Reusability in Hierarchical RL

Researchers have developed a new algorithm called CARL (Contrastive Action-based Representations for Reusable Local Control) to improve the reusability of skills in Hierarchical Reinforcement Learning (HRL). CARL exploits the regularity of local dynamics, suggesting that similar action sequences are needed for transitions in different global contexts. By aligning these contexts with their required action sequences, the algorithm learns where and which skills to reuse, potentially benefiting various HRL algorithms. The method has demonstrated qualitative skill clustering in complex environments and improved performance on the OGBench benchmark when integrated with HIQL. AI

    Exploiting Local Dynamics Regularity for Reusable Skills in Offline Hierarchical RL

    arXiv:2605.26371v1 Announce Type: new Abstract: Hierarchical Reinforcement Learning (HRL) promises to solve long-horizon Reinforcement Learning (RL) tasks more efficiently than non-hierarchical counterparts by discovering and reusing temporally-extended skills. However, obtaining…
