StructRL for Long-Horizon Vision-Language-Action Tasks
September 27, 2026
StructRL is an online reinforcement learning framework that uses verifiable subtask completions to provide intermediate rewards. This overcomes the sparse reward problem in long-horizon manipulation tasks by rewarding progress toward specific milestones.
