Transformer-Exclusive Cross-Modal Representation for Vision and Language

Ever since the advent of deep learning, crossmodal representation learning has been dominated by the approaches involving convolutional neural networks for visual representation and recurrent neural networks for language representation. Transformer architecture, however, has rapidly taken over the recurrent neural networks in natural language processing tasks, and it has also been shown that vision tasks can be handled with transformer architecture, with compatible performance to convolutional neural networks. Such results naturally lead to speculation upon the possibility of tackling cross-modal representation for vision and language exclusively with transformer. This paper examines transformerexclusive cross-modal representation to explore such possibility, demonstrating its potentials as well as discussing its current limitations and its prospects.
