论文摘要
在本文中，我们设计和培训生成的图像到文本变压器Git，以统一视觉语言任务，例如图像/视频字幕和问题答案。尽管生成模型在预训练和微调之间提供了一致的网络体系结构，但现有工作通常包含复杂的结构（uni/多模式编码器/解码器），并取决于外部模块，例如对象检测器/taggers和光学角色识别（OCR）。在git中，我们将体系结构简化为一个图像编码器，而在单语言建模任务下将架构简化为一个文本解码器。我们还扩大了训练数据和模型大小以提高模型性能。没有铃铛和哨子，我们的git在12个具有挑战性的基准下建立了新的艺术状态。例如，我们的模型在文本贴图上首次超过了人类的表现（138.2 vs. 125.5在苹果酒中）。此外，我们提出了一种新的基于一代的图像分类和场景文本识别的方案，在标准基准上实现了不错的表现。代码以\ url {https://github.com/microsoft/generativeimage2text}发布。
In this paper, we design and train a Generative Image-to-text Transformer, GIT, to unify vision-language tasks such as image/video captioning and question answering. While generative models provide a consistent network architecture between pre-training and fine-tuning, existing work typically contains complex structures (uni/multi-modal encoder/decoder) and depends on external modules such as object detectors/taggers and optical character recognition (OCR). In GIT, we simplify the architecture as one image encoder and one text decoder under a single language modeling task. We also scale up the pre-training data and the model size to boost the model performance. Without bells and whistles, our GIT establishes new state of the arts on 12 challenging benchmarks with a large margin. For instance, our model surpasses the human performance for the first time on TextCaps (138.2 vs. 125.5 in CIDEr). Furthermore, we present a new scheme of generation-based image classification and scene text recognition, achieving decent performance on standard benchmarks.
