Improving Multi-fidelity Optimization with a Recurring Learning Rate for Hyperparameter Tuning

no code implementations26 Sep 2022 Hyunjae Lee, Gihyeon Lee, Junhwan Kim, Sungjun Cho, Dohyun Kim, Donggeun Yoo

However, it often results in selecting a sub-optimal configuration as training with the high-performing configuration typically converges slowly in an early phase.

Interactive Multi-Class Tiny-Object Detection

1 code implementation CVPR 2022 Chunggi Lee, Seonwook Park, Heon Song, Jeongun Ryu, Sanghoon Kim, Haejoon Kim, Sérgio Pereira, Donggeun Yoo

We perform experiments on the Tiny-DOTA and LCell datasets using both two-stage and one-stage object detection architectures to verify the efficacy of our approach.

Learning Visual Context by Comparison

2 code implementations ECCV 2020 Minchul Kim, Jongchan Park, Seil Na, Chang Min Park, Donggeun Yoo

Current methods for solving this task exploit various characteristics of the chest X-ray image, but one of the most important characteristics is still missing: the necessity of comparison between related regions in an image.

Reducing Domain Gap by Reducing Style Bias

3 code implementations CVPR 2021 Hyeonseob Nam, Hyunjae Lee, Jongchan Park, Wonjun Yoon, Donggeun Yoo

Convolutional Neural Networks (CNNs) often fail to maintain their performance when they confront new test domains, which is known as the problem of domain shift.

PseudoEdgeNet: Nuclei Segmentation only with Point Annotations

2 code implementations7 Jun 2019 Inwan Yoo, Donggeun Yoo, Kyunghyun Paeng

In this paper, we propose a weakly supervised nuclei segmentation method, which requires only point annotations for training.

Learning Loss for Active Learning

6 code implementations CVPR 2019 Donggeun Yoo, In So Kweon

In this paper, we propose a novel active learning method that is simple but task-agnostic, and works efficiently with the deep networks.

Distort-and-Recover: Color Enhancement using Deep Reinforcement Learning

no code implementations CVPR 2018 Jongchan Park, Joon-Young Lee, Donggeun Yoo, In So Kweon

In addition, we present a 'distort-and-recover' training scheme which only requires high-quality reference images for training instead of input and retouched image pairs.

Learning Image Representations by Completing Damaged Jigsaw Puzzles

no code implementations6 Feb 2018 Dahun Kim, Donghyeon Cho, Donggeun Yoo, In So Kweon

The recovery of the aforementioned damage pushes the network to obtain robust and general-purpose representations.

Two-Phase Learning for Weakly Supervised Object Localization

no code implementations ICCV 2017 Dahun Kim, Donghyeon Cho, Donggeun Yoo, In So Kweon

Weakly supervised semantic segmentation and localiza- tion have a problem of focusing only on the most important parts of an image since they use only image-level annota- tions.

Action-Driven Object Detection with Top-Down Visual Attentions

no code implementations20 Dec 2016 Donggeun Yoo, Sunggyun Park, Kyunghyun Paeng, Joon-Young Lee, In So Kweon

In this paper, we present an "action-driven" detection mechanism using our "top-down" visual attention model.
