Unexplored Faces of Robustness and Out-of-Distribution: Covariate Shifts in Environment and Sensor Domains

1 code implementation24 Apr 2024 Eunsu Baek, Keondo Park, Jiyoon Kim, Hyung-Sin Kim

We find that existing OOD detection methods do not cope with the covariate shifts in ImageNet-ES, implying that the definition and detection of OOD should be revisited to embrace real-world distribution shifts.

Out of Distribution (OOD) Detection

SlAction: Non-intrusive, Lightweight Obstructive Sleep Apnea Detection using Infrared Video

no code implementations6 Sep 2023 You Rim Choi, Gyeongseon Eo, Wonhyuck Youn, Hyojin Lee, Haemin Jang, Dongyoon Kim, Hyunwoo Shin, Hyung-Sin Kim

Recognizing that sleep videos exhibit minimal motion, this work investigates the fundamental question: "Are respiratory events adequately reflected in human motions during sleep?"

UpCycling: Semi-supervised 3D Object Detection without Sharing Raw-level Unlabeled Scenes

no code implementations ICCV 2023 Sunwook Hwang, Youngseok Kim, Seongwon Kim, Saewoong Bahk, Hyung-Sin Kim

In this paper, we propose UpCycling, a novel SSL framework for 3D object detection with zero additional raw-level point cloud: learning from unlabeled de-identified intermediate features (i. e., smashed data) to preserve privacy.

Bitwidth-Adaptive Quantization-Aware Neural Network Training: A Meta-Learning Approach

1 code implementation20 Jul 2022 Jiseok Youn, Jaehun Song, Hyung-Sin Kim, Saewoong Bahk

By comparing their performance to (bitwidth-dedicated) QAT, existing bitwidth adaptive QAT and vanilla meta-learning, we find that merging bitwidths into meta-learning tasks achieves a higher level of robustness.

Federated Semi-Supervised Learning with Prototypical Networks

1 code implementation27 May 2022 Woojung Kim, Keondo Park, Kihyuk Sohn, Raphael Shu, Hyung-Sin Kim

Compared to a FSSL approach based on weight sharing, the prototype-based inter-client knowledge sharing significantly reduces both communication and computation costs, enabling more frequent knowledge sharing between more clients for better accuracy.

Personalized Federated Learning with Server-Side Information

1 code implementation23 May 2022 Jaehun Song, Min-hwan Oh, Hyung-Sin Kim

Personalized Federated Learning (FL) is an emerging research field in FL that learns an easily adaptable global model in the presence of data heterogeneity among clients.
