DAFA: Distance-Aware Fair Adversarial Training

1 code implementation23 Jan 2024 Hyungyu Lee, Saehyung Lee, Hyemi Jang, Junsung Park, Ho Bae, Sungroh Yoon

The disparity in accuracy between classes in standard training is amplified during adversarial training, a phenomenon termed the robust fairness problem.

Sample-efficient Adversarial Imitation Learning

no code implementations14 Mar 2023 Dahuin Jung, Hyungyu Lee, Sungroh Yoon

In particular, in comparison with existing self-supervised learning methods for tabular data, we propose a different corruption method for state and action representations that is robust to diverse distortions.

Removing Undesirable Feature Contributions Using Out-of-Distribution Data

1 code implementation ICLR 2021 Saehyung Lee, Changhwa Park, Hyungyu Lee, Jihun Yi, Jonghyun Lee, Sungroh Yoon

Herein, we propose a data augmentation method to improve generalization in both adversarial and standard learning by using out-of-distribution (OOD) data that are devoid of the abovementioned issues.

Adversarial Vertex Mixup: Toward Better Adversarially Robust Generalization

2 code implementations CVPR 2020 Saehyung Lee, Hyungyu Lee, Sungroh Yoon

In this paper, we identify Adversarial Feature Overfitting (AFO), which may cause poor adversarially robust generalization, and we show that adversarial training can overshoot the optimal point in terms of robust generalization, leading to AFO in our simple Gaussian model.

Security and Privacy Issues in Deep Learning

no code implementations31 Jul 2018 Ho Bae, Jaehee Jang, Dahuin Jung, Hyemi Jang, Heonseok Ha, Hyungyu Lee, Sungroh Yoon

Furthermore, the privacy of the data involved in model training is also threatened by attacks such as the model-inversion attack, or by dishonest service providers of AI applications.
