  • 用差分放大器思路设计注意力机制,抑制视觉噪声干扰
  • 在18个RLBench任务上平均成功率最优,训练时间减少三分之一
  • 适合高精度实物操作场景,如精准插钉、投镖入靶

基于注意力机制的多视角机器人操作方法在训练效率和任务表现上已取得显著进展。然而,机器人视角图像中存在的固有冗余、遮挡和视角依赖问题常导致严重注意力漂移。为此,我们提出AmpAttention,一种受模拟电路中差分放大器启发的新注意力机制,旨在抑制注意力噪声,捕捉信噪比更高的信号以实现更可靠的感知。在此基础上,我们构建了集成任务引导的视内与视间AmpAttention的RVAF模型。相较于此前最先进方法,RVAF在18个RLBench任务(共249个变体)上实现了最优平均成功率,同时将训练时间减少33.3%。该模型在真实世界高精度任务中也展现出强潜力,例如成功抓取飞镖并精准插入红心靶心。进一步地,通过引入SAM2图像编码器,我们将RVAF扩展为RVAF++,在高精度任务上取得显著提升,在‘insert peg’任务上达到91%的成功率。更多定性结果见匿名项目网站 https://anonymous.4open.science/w/RVAF-Anonymization。

原文摘要 · Abstract (English)

Multi-view robotic manipulation methods with the attention mechanism have recently achieved significant progress in both training efficiency and task performance. However, the inherent redundancy, occlusion, and viewpoint dependency in robotic view images often lead to severe attention drift. To address this challenge, we propose AmpAttention, a novel attention mechanism inspired by differential amplifiers in analog circuits. It aims to suppress attention noise and capture high signal-to-noise ratio signals for more reliable perception. Based on this, we introduce the RVAF model, which integrates task-guided intra-view and inter-view AmpAttention. Compared to previous state-of-the-art methods, RVAF achieves the optimal average success rate across 18 RLBench tasks (249 variations) while reducing training time by 33.3\%. RVAF also demonstrates strong potential in real-world high-precision tasks, exemplified by its ability to pick up a dart and accurately insert it into the red bullseye. Furthermore, we extend RVAF to RVAF++ by incorporating the SAM2 image encoder. RVAF++ achieves substantial gains on high-precision tasks, achieving a 91\% success rate on the `insert peg' task.
