Towards Open-Set Test-Time Adaptation Utilizing the Wisdom of Crowds in Entropy Minimization

1 code implementation ICCV 2023 Jungsoo Lee, Debasmit Das, Jaegul Choo, Sungha Choi

To be more specific, entropy minimization attempts to raise the confidence values of an individual sample's prediction, but individual confidence values may rise or fall due to the influence of signals from numerous other predictions (i. e., wisdom of crowds).

Progressive Random Convolutions for Single Domain Generalization

no code implementations CVPR 2023 Seokeon Choi, Debasmit Das, Sungha Choi, Seunghan Yang, Hyunsin Park, Sungrack Yun

Single domain generalization aims to train a generalizable model with only one source domain to perform well on arbitrary unseen target domains.

EcoTTA: Memory-Efficient Continual Test-time Adaptation via Self-distilled Regularization

1 code implementation CVPR 2023 Junha Song, Jungsoo Lee, In So Kweon, Sungha Choi

Second, our novel self-distilled regularization controls the output of the meta networks not to deviate significantly from the output of the frozen original networks, thereby preserving well-trained knowledge from the source domain.

TTN: A Domain-Shift Aware Batch Normalization in Test-Time Adaptation

no code implementations10 Feb 2023 Hyesu Lim, Byeonggeun Kim, Jaegul Choo, Sungha Choi

In this paper, we identify that CBN and TBN are in a trade-off relationship and present a new test-time normalization (TTN) method that interpolates the statistics by adjusting the importance between CBN and TBN according to the domain-shift sensitivity of each BN layer.

Improving Test-Time Adaptation via Shift-agnostic Weight Regularization and Nearest Source Prototypes

no code implementations24 Jul 2022 Sungha Choi, Seunghan Yang, Seokeon Choi, Sungrack Yun

This paper proposes a novel test-time adaptation strategy that adjusts the model pre-trained on the source domain using only unlabeled online data from the target domain to alleviate the performance degradation due to the distribution shift between the source and target domains.

Standardized Max Logits: A Simple yet Effective Approach for Identifying Unexpected Road Obstacles in Urban-Scene Segmentation

1 code implementation ICCV 2021 Sanghun Jung, Jungsoo Lee, Daehoon Gwak, Sungha Choi, Jaegul Choo

However, the distribution of max logits of each predicted class is significantly different from each other, which degrades the performance of identifying unexpected objects in urban-scene segmentation.

Towards Lightweight Lane Detection by Optimizing Spatial Embedding

1 code implementation arXiv.org 2020 Seokwoo Jung, Sungha Choi, Mohammad Azam Khan, Jaegul Choo

This paper addresses the problem that pixel embedding in proposal-free instance segmentation based lane detection is difficult to optimize.

Cars Can't Fly up in the Sky: Improving Urban-Scene Segmentation via Height-driven Attention Networks

1 code implementation CVPR 2020 Sungha Choi, Joanne T. Kim, Jaegul Choo

This paper exploits the intrinsic features of urban-scene images and proposes a general add-on module, called height-driven attention networks (HANet), for improving semantic segmentation for urban-scene images.

Image-to-Image Translation via Group-wise Deep Whitening-and-Coloring Transformation

2 code implementations CVPR 2019 Wonwoong Cho, Sungha Choi, David Keetae Park, Inkyu Shin, Jaegul Choo

However, applying this approach in image translation is computationally intensive and error-prone due to the expensive time complexity and its non-trivial backpropagation.
