Robust Proxy: Improving Adversarial Robustness by Robust Proxy Learning

no code implementations27 Jun 2023 Hong Joo Lee, Yong Man Ro

With the class-wise robust features, the model explicitly learns adversarially robust features through the proposed robust proxy learning framework.

Advancing Adversarial Training by Injecting Booster Signal

no code implementations27 Jun 2023 Hong Joo Lee, Youngjoon Yu, Yong Man Ro

Different from the previous approaches, in this paper, we propose a new approach to improve the adversarial robustness by using an external signal rather than model parameters.

Investigating Vulnerability to Adversarial Examples on Multimodal Data Fusion in Deep Learning

no code implementations22 May 2020 Youngjoon Yu, Hong Joo Lee, Byeong Cheon Kim, Jung Uk Kim, Yong Man Ro

The success of multimodal data fusion in deep learning appears to be attributed to the use of complementary in-formation between multiple input data.
