摘要:

多模态图文模型在过去几年中展现出卓越性能。然而,在将其应用于真实场景之前,评估其对分布偏移的鲁棒性至关重要。在本工作中,我们研究了12种流行的开源图文模型在常见扰动下、于五项任务(图文检索、视觉推理、视觉蕴含、图像描述和文本到图像生成)上的鲁棒性。具体而言,我们在现有数据集之上应用17种图像扰动技术和16种文本扰动技术,提出了若干新的多模态鲁棒性基准。我们观察到,多模态模型对图像和文本扰动并不鲁棒,尤其是对图像扰动。在测试的扰动方法中,字符级扰动构成文本最严重的分布偏移,而缩放模糊(zoom blur)是图像数据最严重的偏移。我们还引入了两个新的鲁棒性指标(用于多模态影响分数的MMI和用于缺失对象率的MOR),以恰当评估多模态模型。我们希望这项广泛研究能为鲁棒多模态模型的发展提供新方向。更多细节可在项目网页 https://MMRobustness.github.io 上找到。

英文摘要:

Multimodal image-text models have shown remarkable performance in the past few years. However, evaluating robustness against distribution shifts is crucial before adopting them in real-world applications. In this work, we investigate the robustness of 12 popular open-sourced image-text models under common perturbations on five tasks (image-text retrieval, visual reasoning, visual entailment, image captioning, and text-to-image generation). In particular, we propose several new multimodal robustness benchmarks by applying 17 image perturbation and 16 text perturbation techniques on top of existing datasets. We observe that multimodal models are not robust to image and text perturbations, especially to image perturbations. Among the tested perturbation methods, character-level perturbations constitute the most severe distribution shift for text, and zoom blur is the most severe shift for image data. We also introduce two new robustness metrics (\textbf{MMI} for MultiModal Impact score and \textbf{MOR} for Missing Object Rate) for proper evaluations of multimodal models. We hope our extensive study sheds light on new directions for the development of robust multimodal models. More details can be found on the project webpage: \url{https://MMRobustness.github.io}.
