+Code for the findings of ACL2022 long paper [UNIMO-2: End-to-End Unified Vision-Language Grounded Learning](https://arxiv.org/pdf/2203.09067.pdf)
+
+
+Abstract
+---
+
+Vision-Language Pre-training (VLP) has achieved impressive performance on various cross-modal downstream tasks. 
+However, most existing methods can only learn from aligned image-caption data and rely heavily on expensive regional 
+features, which greatly limits their scalability and performance. In this paper, we propose an end-to-end unified-modal 
+pre-training framework, namely UNIMO-2, for joint learning on both aligned image-caption data and unaligned image-only 
+and text-only corpus. We build a unified Transformer model to jointly learn visual representations, textual 
+representations and semantic alignment between images and texts. In particular, we propose to conduct grounded learning 
+on both images and texts via a sharing grounded space, which helps bridge unaligned images and texts, and align the 
+visual and textual semantic spaces on different types of corpora. The experiments show that our grounded learning 
+method can improve textual and visual semantic alignment for improving performance on various cross-modal tasks. 
+Moreover, benefiting from effective joint modeling of different types of corpora, our model also achieves impressive 
+performance on single-modal visual and textual tasks. Our code and models are public at the UNIMO project page 
+\url{https://unimo-ptm.github.io}.

+Pre-trained Models
+---
+Similar to UNIMO, UNIMO-2 adopts large-scale text corpus, image collections and image-text aligned datasets as the pre-training data. 
+We provide pre-trained UNIMO-2 models:
+
+```
+cd /path/to/model_files
+wget --no-check-certificate -q https://unimo-2.bj.bcebos.com/model/UNIMO-2.tar.gz
+tar -zxf UNIMO-2.tar.gz
+```
+
+
+Experiments
+---
+
+Our fine-tuning experiments are carried on V100 GPU. Here are the results from the UNIMO-2 model:
+
+
