... Vision-Language Pretraining (VLP) has achieved impressive performance on many multimodal downstream tasks.
However, the requirement for expensive annotations ... limits the scalability of existing approaches
... relax these constraints and present a minimalist pretraining framework, named Simple Visual Language Model (SimVLM).
... by exploiting large-scale weak supervision, and is trained end-to-end with a single prefix language modeling objective.
Without utilizing extra data or task-specific customization, the resulting model significantly outperforms previous pretraining methods and achieves new state-of-the-art results on a wide range of discriminative and generative vision-language benchmarks, including VQA (+3.74% vqa-score), NLVR2 (+1.17% accuracy), SNLI-VE (+1.37% accuracy) and image captioning tasks (+10.1% average CIDEr score).
... demonstrate that SimVLM acquires strong generalization and transfer ability, enabling zero-shot behavior including open-ended visual question answering and cross-modality transfer.
