BiasAdv: Bias-Adversarial Augmentation for Model Debiasing

no code implementations CVPR 2023 Jongin Lim, Youngdong Kim, Byungjai Kim, Chanho Ahn, Jinwoo Shin, Eunho Yang, Seungju Han

Our key idea is that an adversarial attack on a biased model that makes decisions based on spurious correlations may generate synthetic bias-conflicting samples, which can then be used as augmented training data for learning a debiased model.

Attention Guided Metal Artifact Correction in MRI using Deep Neural Networks

no code implementations19 Oct 2019 Jee Won Kim, Kinam Kwon, Byungjai Kim, HyunWook Park

In this paper, we observed that in a real MRI environment, two distorted images obtained with opposite polarities of readout gradient showed artifacts in a different region.
