AI总结:

M3-AD提出了一种反思-aware 的多模态框架,通过RA-Monitor提升工业异常检测的鲁棒性和可靠性。

摘要:

尽管多模态大语言模型(MLLMs)已将工业异常检测推向零样本范式,但它们在细粒度和结构复杂的工业场景中仍倾向于产生高置信度但不可靠的决策,并缺乏有效的自我纠正机制。为了解决这一问题,我们提出了M3-AD,一个统一的反思-aware 多模态框架用于工业异常检测。M3-AD包含两个互补的数据资源:M3-AD-FT,用于反思对齐的微调,以及M3-AD-Bench,用于系统性的跨类别评估,共同为反思-aware 学习和可靠性评估提供基础。在此基础上,我们提出了RA-Monitor,它将反思建模为可学习的决策修订过程,并指导模型在初始判断不可靠时进行受控的自我纠正,从而提高决策鲁棒性。在M3-AD-Bench上进行的大量实验表明,RA-Monitor在零样本异常检测和异常分析任务中优于多个开源和商业MLLMs。代码将在https://github.com/Yanhui-Lee/M3-AD上发布。

英文摘要:

Although multimodal large language models (MLLMs) have advanced industrial anomaly detection toward a zero-shot paradigm, they still tend to produce high-confidence yet unreliable decisions in fine-grained and structurally complex industrial scenarios, and lack effective self-corrective mechanisms. To address this issue, we propose M3-AD, a unified reflection-aware multimodal framework for industrial anomaly detection. M3-AD comprises two complementary data resources: M3-AD-FT, designed for reflection-aligned fine-tuning, and M3-AD-Bench, designed for systematic cross-category evaluation, together providing a foundation for reflection-aware learning and reliability assessment. Building upon this foundation, we propose RA-Monitor, which models reflection as a learnable decision revision process and guides models to perform controlled self-correction when initial judgments are unreliable, thereby improving decision robustness. Extensive experiments conducted on M3-AD-Bench demonstrate that RA-Monitor outperforms multiple open-source and commercial MLLMs in zero-shot anomaly detection and anomaly analysis tasks. Code will be released at https://github.com/Yanhui-Lee/M3-AD.
