Theoretical Understanding of Learning from Adversarial Perturbations

1 code implementation16 Feb 2024 Soichiro Kumano, Hiroshi Kera, Toshihiko Yamasaki

In this study, we provide a theoretical framework for understanding learning from perturbations using a one-hidden-layer network trained on mutually orthogonal samples.

Improving Robustness to Out-of-Distribution Data by Frequency-based Augmentation

no code implementations6 Sep 2022 Koki Mukai, Soichiro Kumano, Toshihiko Yamasaki

In order to improve the robustness against out-of-distribution data, we present a frequency-based data augmentation technique that replaces the frequency components with other images of the same class.

Superclass Adversarial Attack

no code implementations29 May 2022 Soichiro Kumano, Hiroshi Kera, Toshihiko Yamasaki

Adversarial attacks have only focused on changing the predictions of the classifier, but their danger greatly depends on how the class is mistaken.

Adversarial Attack Multi-Label Classification

Are DNNs fooled by extremely unrecognizable images?

1 code implementation7 Dec 2020 Soichiro Kumano, Hiroshi Kera, Toshihiko Yamasaki

In this paper, we address the question of whether there can be fooling images with no characteristic pattern of natural objects locally or globally.
