摘要:

最近,来自视频数据的多模态学习受到了越来越多的关注,因为它允许在没有人类注释的情况下训练语义上有意义的嵌入,从而实现zero-shot检索和分类等任务。在这项工作中,我们提出了一个多模态,模态不可知的融合Transformer的方法,学习多模态之间的信息交换,如视频,音频和文本,并将它们集成到一个联合的多模态表示,以获得一个嵌入,聚合多模态的时间信息。我们建议训练系统的组合损失的一切在一次,单一的模态以及对模态,明确地离开了任何附加组件,如位置或模态编码。在测试时,生成的模型可以处理和融合任何数量的输入模态。此外,Transformer的隐式属性允许处理不同长度的输入。为了评估所提出的方法,我们训练的大规模HowTo100 M数据集上的模型,并评估所得到的嵌入空间在四个具有挑战性的基准数据集上获得最先进的结果,在zero-shot视频检索和zero-shot视频动作定位。

英文摘要:

Multi-modal learning from video data has seen increased attention recently as it allows to train semantically meaningful embeddings without human annotation enabling tasks like zero-shot retrieval and classification. In this work, we present a multi-modal, modality agnostic fusion transformer approach that learns to exchange information between multiple modalities, such as video, audio, and text, and integrate them into a joined multi-modal representation to obtain an embedding that aggregates multi-modal temporal information. We propose to train the system with a combinatorial loss on everything at once, single modalities as well as pairs of modalities, explicitly leaving out any add-ons such as position or modality encoding. At test time, the resulting model can process and fuse any number of input modalities. Moreover, the implicit properties of the transformer allow to process inputs of different lengths. To evaluate the proposed approach, we train the model on the large scale HowTo100M dataset and evaluate the resulting embedding space on four challenging benchmark datasets obtaining state-of-the-art results in zero-shot video retrieval and zero-shot video action localization.
