Fair Contrastive Learning for Facial Attribute Classification

1 code implementation CVPR 2022 Sungho Park, Jewook Lee, Pilhyeon Lee, Sunhee Hwang, Dohyung Kim, Hyeran Byun

Through extensive experiments on CelebA and UTK Face, we validate that the proposed method significantly outperforms SupCon and existing state-of-the-art methods in terms of the trade-off between top-1 accuracy and fairness.

Distance-aware Quantization

no code implementations ICCV 2021 Dohyung Kim, Junghyup Lee, Bumsub Ham

This alleviates the gradient mismatch, but causes a quantizer gap problem.


Decoding the shift-invariant data: applications for band-excitation scanning probe microscopy

1 code implementation20 Apr 2021 Yongtao Liu, Rama K. Vasudevan, Kyle Kelley, Dohyung Kim, Yogesh Sharma, Mahshid Ahmadi, Sergei V. Kalinin, Maxim Ziatdinov

A shift-invariant variational autoencoder (shift-VAE) is developed as an unsupervised method for the analysis of spectral data in the presence of shifts along the parameter axis, disentangling the physically-relevant shifts from other latent variables.

Network Quantization with Element-wise Gradient Scaling

1 code implementation CVPR 2021 Junghyup Lee, Dohyung Kim, Bumsub Ham

Network quantization aims at reducing bit-widths of weights and/or activations, particularly important for implementing deep neural networks with limited hardware resources.

README: REpresentation learning by fairness-Aware Disentangling MEthod

no code implementations7 Jul 2020 Sungho Park, Dohyung Kim, Sunhee Hwang, Hyeran Byun

After the representation learning, this disentangled representation is leveraged for fairer downstream classification by excluding the subspace with the protected attribute information.

ETRI-Activity3D: A Large-Scale RGB-D Dataset for Robots to Recognize Daily Activities of the Elderly

1 code implementation4 Mar 2020 Jinhyeok Jang, Dohyung Kim, Cheonshu Park, Minsu Jang, Jaeyeon Lee, Jaehong Kim

To cope with this situation, we introduce a new dataset called ETRI-Activity3D, focusing on the daily activities of the elderly in robot-view.

Learning Semantic Correspondence Exploiting an Object-level Prior

no code implementations29 Nov 2019 Junghyup Lee, Dohyung Kim, Wonkyung Lee, Jean Ponce, Bumsub Ham

We address the problem of semantic correspondence, that is, establishing a dense flow field between images depicting different instances of the same object or scene category.
