摘要:
视觉语言模型(VLMs)在大规模、复杂且难以解释的架构上编码多模态输入,限制了透明度和信任度。我们提出了一种多模态逆向用于模型解释和概念化(MIMIC)框架,用于逆向VLM的内部编码。MIMIC利用基于VLM的联合逆向和特征对齐目标,以应对VLM的自回归处理。它还包含一个三元组的正则化器,用于空间对齐、自然图像平滑性和语义真实性。我们通过在各种自由形式VLM输出上逆向视觉概念,从定量和定性方面评估MIMIC。报告的结果包括标准视觉质量度量和基于语义的文本度量。据我们所知,这是首个针对VLM概念视觉解释的模型逆向方法。
英文摘要:
Vision Language Models (VLMs) encode multimodal inputs over large, complex, and difficult-to-interpret architectures, which limit transparency and trust. We propose a Multimodal Inversion for Model Interpretation and Conceptualization (MIMIC) framework that inverts the internal encodings of VLMs. MIMIC uses a joint VLM-based inversion and a feature alignment objective to account for VLM's autoregressive processing. It additionally includes a triplet of regularizers for spatial alignment, natural image smoothness, and semantic realism. We evaluate MIMIC both quantitatively and qualitatively by inverting visual concepts across a range of free-form VLM outputs of varying length. Reported results include both standard visual quality metrics and semantic text-based metrics. To the best of our knowledge, this is the first model inversion approach addressing visual interpretations of VLM concepts.
