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).

Improving Scene Text Recognition for Character-Level Long-Tailed Distribution

no code implementations31 Mar 2023 Sunghyun Park, Sunghyo Chung, Jungsoo Lee, Jaegul Choo

However, STR models show a large performance degradation on languages with a numerous number of characters (e. g., Chinese and Korean), especially on characters that rarely appear due to the long-tailed distribution of characters in such languages.

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.

Deep Imbalanced Time-series Forecasting via Local Discrepancy Density

1 code implementation27 Feb 2023 Junwoo Park, Jungsoo Lee, Youngin Cho, Woncheol Shin, Dongmin Kim, Jaegul Choo, Edward Choi

Based on our findings, we propose a reweighting framework that down-weights the losses incurred by abrupt changes and up-weights those by normal states.

Improving Evaluation of Debiasing in Image Classification

no code implementations8 Jun 2022 Jungsoo Lee, Juyoung Lee, Sanghun Jung, Jaegul Choo

Based on such issues, this paper 1) proposes an evaluation metric `Align-Conflict (AC) score' for the tuning criterion, 2) includes experimental settings with low bias severity and shows that they are yet to be explored, and 3) unifies the standardized experimental settings to promote fair comparisons between debiasing methods.

CAFA: Class-Aware Feature Alignment for Test-Time Adaptation

no code implementations ICCV 2023 Sanghun Jung, Jungsoo Lee, Nanhee Kim, Amirreza Shaban, Byron Boots, Jaegul Choo

That is, a model does not have a chance to learn test data in a class-discriminative manner, which was feasible in other adaptation tasks (\textit{e. g.,} unsupervised domain adaptation) via supervised losses on the source data.

Revisiting the Importance of Amplifying Bias for Debiasing

no code implementations29 May 2022 Jungsoo Lee, Jeonghoon Park, Daeyoung Kim, Juyoung Lee, Edward Choi, Jaegul Choo

$f_B$ is trained to focus on bias-aligned samples (i. e., overfitted to the bias) while $f_D$ is mainly trained with bias-conflicting samples by concentrating on samples which $f_B$ fails to learn, leading $f_D$ to be less susceptible to the dataset bias.

Improving Face Recognition with Large Age Gaps by Learning to Distinguish Children

1 code implementation22 Oct 2021 Jungsoo Lee, Jooyeol Yun, Sunghyun Park, Yonggyu Kim, Jaegul Choo

Despite the unprecedented improvement of face recognition, existing face recognition models still show considerably low performances in determining whether a pair of child and adult images belong to the same identity.

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.

Learning Debiased Representation via Disentangled Feature Augmentation

1 code implementation NeurIPS 2021 Jungsoo Lee, Eungyeup Kim, Juyoung Lee, Jihyeon Lee, Jaegul Choo

To this end, our method learns the disentangled representation of (1) the intrinsic attributes (i. e., those inherently defining a certain class) and (2) bias attributes (i. e., peripheral attributes causing the bias), from a large number of bias-aligned samples, the bias attributes of which have strong correlation with the target variable.
