Self-accumulative Vision Transformer for Bone Age Assessment Using the Sauvegrain Method

no code implementations29 Mar 2023 Hong-Jun Choi, Dongbin Na, Kyungjin Cho, Byunguk Bae, Seo Taek Kong, Hyunjoon An

This study presents a novel approach to bone age assessment (BAA) using a multi-view, multi-task classification model based on the Sauvegrain method.

Bag of Tricks for In-Distribution Calibration of Pretrained Transformers

1 code implementation13 Feb 2023 Jaeyoung Kim, Dongbin Na, Sungchul Choi, Sungbin Lim

We find that the ensemble model overfitted to the training set shows sub-par calibration performance and also observe that PLMs trained with confidence penalty loss have a trade-off between calibration and accuracy.

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.
