AI总结:

提出跨模态知识编辑基准UniKE,发现文本编辑在图像生成中效果显著下降(VQA准确率仅18.5%),并提出推理增强参数编辑方法提升跨模态迁移效果。

摘要:

统一多模态模型(UMMs)已成为通用多模态智能的有前途的范式。随着它们在现实世界应用中的部署,有效更新内部知识变得至关重要。虽然知识编辑在纯文本模型中已经成熟,但成功修改文本输出的编辑是否也能迁移到UMMs中的图像生成仍不清楚。为了研究这个问题,我们引入了UniKE,这是第一个用于UMMs中跨模态知识编辑的基准,包含2,971个编辑主题,涵盖属性和关系编辑。使用基于VQA的视觉验证,我们揭示了一个显著的模态差距:文本侧的有效性可以达到约92%,而直接图像生成下的最佳整体VQA准确率仅为18.5%。我们进一步提出了推理增强参数编辑,它在生成前显式激活编辑后的知识,并提高了所有评估模型-编辑器对的整体VQA准确率,提升高达18.6个百分点。机制分析表明,这种差距与编辑后的文本表示与视觉生成的条件路径之间的部分对齐有关,其中足以用于文本输出的编辑可能仍然太弱或未对齐,无法引导图像合成。这些发现表明,文本知识编辑不能保证可靠的跨模态迁移,并激励了模态感知的编辑方法。我们的代码和数据可在https://github.com/gxx27/UniKE获取。

英文摘要:

Unified multimodal models (UMMs) have emerged as a promising paradigm for general-purpose multimodal intelligence. As they are deployed in real-world applications, effectively updating internal knowledge becomes critical. While knowledge editing has matured for text-only models, it remains unclear whether edits that successfully modify textual outputs also transfer to image generation in UMMs. To study this question, we introduce UniKE, the first benchmark for cross-modality knowledge editing in UMMs, comprising 2,971 edit subjects spanning attribute and relation edits. Using VQA-based visual verification, we reveal a striking modality gap: text-side efficacy can reach approximately 92%, whereas the best overall VQA accuracy under direct image generation is only 18.5%. We further propose Reasoning-augmented Parameter Editing, which explicitly activates edited knowledge before generation and improves overall VQA accuracy for all evaluated model-editor pairs, with gains up to 18.6 percentage points. Mechanistic analysis shows that this gap is associated with partial alignment between edited textual representations and the conditioning pathways for visual generation, where edits sufficient for text outputs may remain too weak or misaligned to steer image synthesis. These findings show that textual knowledge edits do not guarantee reliable cross-modality transfer and motivate modality-aware editing methods.
