RIFT 方法通过移除迭代视频推出,将机器人动作延迟削减

研究人员开发了 RIFT(Rollout-free Imagination via Future Tokens),一种用于世界动作模型(WAMs)的新颖方法,通过消除迭代视频推出显著降低了延迟。通过使用学习到的预期令牌在单次传递中构建未来的键/值缓存,RIFT 在机器人任务上保持了高成功率。这种方法在实现与传统的基于推出(rollout-based)的方法相当的性能的同时,大幅缩短了动作块(action-chunk)的延迟,并在 LIBERO 和 RoboTwin 2.0 等基准测试中证明了其有效性。 AI

影响 降低了机器人控制系统的延迟,可能为更快、更具响应性的现实世界 AI 应用提供支持。
