Can Vision Transformers Learn without Natural Images?

Kodai Nakashima, Hirokatsu Kataoka, Asato Matsumoto +2

Can we complete pre-training of Vision Transformers (ViT) without natural images and human-annotated labels? Although a pre-trained ViT seems to heavily rely on a large-scale datas…

Describing and Localizing Multiple Changes with Transformers

Yue Qiu, Shintaro Yamamoto, Kodai Nakashima +4

Change captioning tasks aim to detect changes in image pairs observed before and after a scene change and generate a natural language description of the changes. Existing change ca…

Dominant Codewords Selection with Topic Model for Action Recognition

Hirokatsu Kataoka, Masaki Hayashi, Kenji Iwata +3

In this paper, we propose a framework for recognizing human activities that uses only in-topic dominant codewords and a mixture of intertopic vectors. Latent Dirichlet allocation (…

Feature Evaluation of Deep Convolutional Neural Networks for Object Recognition and Detection

Hirokatsu Kataoka, Kenji Iwata, Yutaka Satoh

In this paper, we evaluate convolutional neural network (CNN) features using the AlexNet architecture and very deep convolutional network (VGGNet) architecture. To date, most CNN r…
