视觉语言模型因先验信念误判施工危险

作者 PulseAugur 编辑部 · [1 个来源] ·

研究人员调查了视觉语言模型（VLM）在施工危险检测中频繁发出误报的原因。研究发现，像Qwen2.5-VL-7B和InternVL3.5-8B这样的模型，尽管能准确识别物体及其空间关系，但却深受学习到的共现先验知识的影响。这种偏见导致假阳性率很高，尤其是在有工人在场但未处于危险距离的情况下。虽然对注意力头和神经元层面的干预未能消除这种偏见，但将危险决策建立在模型的空间表征之上可以提高特异性，这表明需要关注决策逻辑，而不仅仅是视觉识别。 AI

影响 突出了当前VLM在安全关键应用中的一个关键限制，表明需要改进决策架构。

    Vision-language models (VLMs) increasingly support construction hazard monitoring, yet their frequent false alarms remain poorly understood. This study investigates whether false struck-by hazard warnings arise from failures in object recognition, spatial relation encoding, or ha…
