摘要:

视觉语言预训练(VLP)提高了许多视觉语言任务的性能。然而,大多数现有的预训练模型仅在基于理解的任务或基于生成的任务中表现出色。此外,性能的提高在很大程度上是通过用从网络上收集的嘈杂的图像-文本对来扩展数据集来实现的,这是一个次优的监督源。在本文中,我们提出了BLIP,一个新的VLP框架,灵活地转移到视觉语言理解和生成任务。BLIP通过自举字幕有效地利用了有噪声的Web数据,其中字幕器生成合成字幕,过滤器去除有噪声的字幕。我们在广泛的视觉语言任务上取得了最先进的结果,例如图像-文本检索(平均召回率为+2.7%),图像描述(CIDER为+2.8%)和VQA(VQA得分为+1.6%)。当以zero-shot方式直接转移到视频语言任务时,BLIP也表现出很强的泛化能力。代码、模型和数据集发布于https://github.com/salesforce/BLIP。

英文摘要:

Vision-Language Pre-training (VLP) has advanced the performance for many vision-language tasks. However, most existing pre-trained models only excel in either understanding-based tasks or generation-based tasks. Furthermore, performance improvement has been largely achieved by scaling up the dataset with noisy image-text pairs collected from the web, which is a suboptimal source of supervision. In this paper, we propose BLIP, a new VLP framework which transfers flexibly to both vision-language understanding and generation tasks. BLIP effectively utilizes the noisy web data by bootstrapping the captions, where a captioner generates synthetic captions and a filter removes the noisy ones. We achieve state-of-the-art results on a wide range of vision-language tasks, such as image-text retrieval (+2.7% in average recall@1), image captioning (+2.8% in CIDEr), and VQA (+1.6% in VQA score). BLIP also demonstrates strong generalization ability when directly transferred to video-language tasks in a zero-shot manner.
