Key Feature Replacement of In-Distribution Samples for Out-of-Distribution Detection

1 code implementation26 Dec 2022 Jaeyoung Kim, Seo Taek Kong, Dongbin Na, Kyu-Hwan Jung

We first deduce that OOD images are perceived by a deep neural network to be semantically similar to in-distribution samples when they share a common background, as deep networks are observed to incorrectly classify such images with high confidence.

A Neural Pre-Conditioning Active Learning Algorithm to Reduce Label Complexity

no code implementations8 Apr 2021 Seo Taek Kong, Soomin Jeon, Dongbin Na, Jaewon Lee, Hong-Seok Lee, Kyu-Hwan Jung

Although unlabeled data is readily available in pool-based AL, AL algorithms are usually evaluated by measuring the increase in supervised learning (SL) performance at consecutive acquisition steps.

Better Optimization can Reduce Sample Complexity: Active Semi-Supervised Learning via Convergence Rate Control

no code implementations1 Jan 2021 Seo Taek Kong, Soomin Jeon, Jaewon Lee, Hong-Seok Lee, Kyu-Hwan Jung

We name this AL scheme convergence rate control (CRC), and our experiments show that a deep neural network trained using a combination of CRC and a recently proposed SSL algorithm can quickly achieve high performance using far less labeled samples than SL.

Resource Optimized Neural Architecture Search for 3D Medical Image Segmentation

no code implementations2 Sep 2019 Woong Bae, Seungho Lee, Yeha Lee, Beomhee Park, Minki Chung, Kyu-Hwan Jung

We propose the resource-optimized neural architecture search method which can be applied to 3D medical segmentation tasks in a short training time (1. 39 days for 1GB dataset) using a small amount of computation power (one RTX 2080Ti, 10. 8GB GPU memory).
