新的Anchor-Align方法提升VLA策略泛化能力

作者 PulseAugur 编辑部 · [1 个来源] ·

研究人员推出了一种名为Anchor-Align的新方法，通过解决标准行为克隆（BC）微调的问题来改进视觉-语言-动作（VLA）策略。BC微调可能会降低预训练视觉-语言模型（VLM）的泛化能力。Anchor-Align通过两个目标增强BC：视觉-语言锚定，它使用来自冻结VLM的蒸馏来保留表示；以及语言-动作对齐，它在同一观察下联合训练语言和动作预测。这种方法在真实机器人成功率以及在模拟和物理xArm7机器人上的各种扰动鲁棒性方面都显示出显著的改进。 AI

影响 通过提高视觉-语言-动作策略的泛化能力和鲁棒性来增强机器人控制。

    通过表示锚定和语言-动作对齐实现可泛化的VLA微调

    Finetuning a pretrained vision-language model (VLM) on robot demonstrations via behavior cloning (BC) has become the standard recipe for vision-language-action (VLA) policies. However, BC finetuning progressively overwrites the pretrained representations that support visual and s…
