研究揭示VLA模型的运动程序与绝对坐标绑定，忽略场景变化

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-20 00:00

研究人员对视觉-语言-动作（VLA）模型进行了机制可解释性研究，发现其运动程序通常与绝对坐标绑定，并且会忽略视觉场景的变化。这种与固定坐标的绑定解释了为什么这些模型在环境发生变化时会显得脆弱。研究还发现，指令编码和运动生成可以在不同架构中分离，一些模型在仅凭场景就能识别目标时会优先考虑视觉信息。 AI

影响揭示了VLA模型的脆弱性，表明在机器人和人工智能领域需要更鲁棒的场景感知运动控制。

并非所有功能都生而平等：视觉-语言-动作模型机制研究

A mechanistic interpretability study of vision-language-action policies reveals that motor programs are bound to absolute coordinates and ignores visual scene changes, with sparse autoencoder analysis separating instruction encoding and motor generation across architectures.
