PT4AL: Using Self-Supervised Pretext Tasks for Active Learning

1 code implementation19 Jan 2022 John Seon Keun Yi, Minseok Seo, Jongchan Park, Dong-Geol Choi

Before the active learning iterations, the pretext task learner is trained on the unlabeled set, and the unlabeled data are sorted and split into batches by their pretext task losses.

The use of computer vision to automate the classification of medical images is widely studied.

Exploiting Features with Split-and-Share Module

no code implementations10 Aug 2021 Jaemin Lee, Minseok Seo, Jongchan Park, Dong-Geol Choi

Deep convolutional neural networks (CNNs) have shown state-of-the-art performances in various computer vision tasks.

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.

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.
