Radiomics-Informed Deep Learning for Classification of Atrial Fibrillation Sub-Types from Left-Atrium CT Volumes

1 code implementation14 Aug 2023 Weihang Dai, Xiaomeng Li, Taihui Yu, Di Zhao, Jun Shen, Kwang-Ting Cheng

Furthermore, we ensure complementary information is learned by deep and radiomic features by designing a novel feature de-correlation loss.

Fundus-Enhanced Disease-Aware Distillation Model for Retinal Disease Classification from OCT Images

1 code implementation1 Aug 2023 Lehan Wang, Weihang Dai, Mei Jin, Chubin Ou, Xiaomeng Li

Our framework enhances the OCT model during training by utilizing unpaired fundus images and does not require the use of fundus images during testing, which greatly improves the practicality and efficiency of our method for clinical use.

Semi-Supervised Deep Regression with Uncertainty Consistency and Variational Model Ensembling via Bayesian Neural Networks

1 code implementation15 Feb 2023 Weihang Dai, Xiaomeng Li, Kwang-Ting Cheng

In this work, we propose a novel approach to semi-supervised regression, namely Uncertainty-Consistent Variational Model Ensembling (UCVME), which improves training by generating high-quality pseudo-labels and uncertainty estimates for heteroscedastic regression.

Cyclical Self-Supervision for Semi-Supervised Ejection Fraction Prediction from Echocardiogram Videos

1 code implementation20 Oct 2022 Weihang Dai, Xiaomeng Li, Xinpeng Ding, Kwang-Ting Cheng

We also introduce teacher-student distillation to distill the information from LV segmentation masks into an end-to-end LVEF regression model that only requires video inputs.
