摘要:

随着社交媒体平台的快速发展,用户正在分享数十亿包含音频,图像和文本的多媒体帖子。研究人员专注于构建能够处理此类多媒体数据的自主系统,以解决具有挑战性的多模态任务,包括跨模态检索,匹配和验证。现有的作品使用单独的网络来提取每种模态的嵌入,以弥合它们之间的差距。其分支网络的模块化结构是创建众多多模态应用程序的基础,并已成为处理多种模态的事实标准。相比之下,我们提出了一种新的单分支网络,能够在不改变网络的情况下学习单峰和多峰任务的判别表示。我们的单分支网络的一个重要特征是,它可以使用单个或多个模态进行训练,而不会牺牲性能。我们评估了我们提出的单分支网络上具有挑战性的多模态问题(面声关联)的跨模态验证和匹配任务与各种损失配方。实验结果表明,我们提出的单分支网络优于现有的方法在广泛的实验。代码:https://github.com/msaadsaeed/SBNet

英文摘要:

With the rapid growth of social media platforms, users are sharing billions of multimedia posts containing audio, images, and text. Researchers have focused on building autonomous systems capable of processing such multimedia data to solve challenging multimodal tasks including cross-modal retrieval, matching, and verification. Existing works use separate networks to extract embeddings of each modality to bridge the gap between them. The modular structure of their branched networks is fundamental in creating numerous multimodal applications and has become a defacto standard to handle multiple modalities. In contrast, we propose a novel single-branch network capable of learning discriminative representation of unimodal as well as multimodal tasks without changing the network. An important feature of our single-branch network is that it can be trained either using single or multiple modalities without sacrificing performance. We evaluated our proposed single-branch network on the challenging multimodal problem (face-voice association) for cross-modal verification and matching tasks with various loss formulations. Experimental results demonstrate the superiority of our proposed single-branch network over the existing methods in a wide range of experiments. Code: https://github.com/msaadsaeed/SBNet
