面向世界动作模型的完成感知引导（CAG）
Completion Aware Guidance for World Action Models
AI 导读
研究者提出 Completion Aware Guidance（CAG），一种免训练采样方法，引导世界动作模型（WAMs）生成能完成任务的动作，缓解"任务未完成的想象"问题。在 RoboTwin 2.0 子集上成功率从 64% 提升至 70%，零样本仿真中从 69% 提升至 75%，任务未完成想象从 79% 降至 40%。

Abstract:World Action Models (WAMs) predict visual futures and robot actions, yet they remain susceptible to task-incomplete imagination, where plausible, action-consistent predictions omit the transition needed for task completion. In this paper, we show that this failure is not inherent to the world model backbone, but emerges when adapted for short-chunk control, which can repeatedly favor plausible local continuations over task-completing transitions. To address this, we introduce Completion Aware Guidance (CAG), a training-free sampling method that guides generation toward task completion. Across representative WAMs, CAG improves success from 64% to 70% on a RoboTwin 2.0 subset and from 69% to 75% in zero-shot simulation, while reducing task-incomplete imagination from 79% to 40%.
