Representation learning has always been a key challenge in many tasks of multi-modality domain, such as image-text retrieval, visual question and answering, video localization, speech recognition, ect. Along the history of multi-modality learning, we find that model initialization is one of the most important factors. For example, research of weight initialization set a foundation of neural network based methods and image features pre-trained with Visual Genome Dataset build a new standard setting for many vision-language models. Recently, multi-modal pre-training is a new paradigm of model initialization that establishes the state-of-the-art performances for many multimedia tasks. Pretraining models outperforms traditional methods by providing stronger representation of different modalities learned in an unsupervised training way. Multi-modal pre-training is an interesting topic and has attracted rapidly growing interests in many fields and the intersection of these them, including computing vision, natural language processing, speech recognition, etc. With the continuous effort of many works, we also find that the cost time can be even decreased to 10 hours on 2 Titan RTXs for a vision-language pre-training model in very recent works. Although the emerging trend of multi-modal pre-training models, it remains unexplored in many aspects. For example, studies of standard settings for fair comparison of different multi-modal pre-training models will benefit the research community. More discussion about the efficiency of sub-modules and pre-training tasks will also help us to have more thorough knowledge about pre-training mechanism. Exploration of improving training efficiency is also worth tackling.
The goals of this workshop are to (1) investigate research opportunities of multi-modal model initialization, especially on multi-modal pre-training, (2) solicit novel methodologies of multi-modal pre-training, (3) explore and discuss the advantage and possibilities of pre-training for more multimedia tasks. We expect contributions concerning multimodality model initialization and multi-modal pre-training, involving image, language, video, speech, etc.

Multi-modal pre-training models have been intensively explored to bridge vision and language in recent years. However, most of them explicitly model the cross-modal interaction between image-text pairs, by assuming that there exists strong semantic correlation between the text and image modalities. Since this strong assumption is often invalid in real-world scenarios, we choose to implicitly model the cross-modal correlation for large-scale multi-modal pre-training, which is the focus of the Chinese project `WenLan' led by our team. Specifically, with the weak correlation assumption over image-text pairs, we propose a two-tower pre-training model called BriVL within the cross-modal contrastive learning framework. We construct a large Chinese multi-source dataset of 650 million image-text pairs for pre-training our model. Extensive experiments demonstrate that WenLan on various downstream tasks and easy to build efficient applications based on searching between images and texts.

Videos are generally accompanied with multi-modal information such as audio, text, and motion. The multi-modal information is becoming an important cue for understanding video content. How to model the correlation between multi-modalities in videos is still an unsolved problem in video understanding tasks such as video action recognition, video temporal grounding, and video description. In this talk, we focus on two specific video understanding tasks (i.e., cross-modal self-supervised pretraining and temporal grounding) by exploiting the video-text cross modal information. In particular, we notice that videos are naturally accompanied by abundant text information such as YouTube titles, Instagram captions, and Movie scripts. This textual information could serve as a general information to guide us train a multi-modal network, which could be used as a general video representation to be fine-tuned on the downstream tasks, or as cross-modal matching similarity to be used for video segment retrieval.
