Dynamic Multimodal Information Bottleneck for Multimodality Classification

1 code implementation2 Nov 2023 Yingying Fang, Shuang Wu, Sheng Zhang, Chaoyan Huang, Tieyong Zeng, Xiaodan Xing, Simon Walsh, Guang Yang

Specifically, our information bottleneck module serves to filter out the task-irrelevant information and noises in the fused feature, and we further introduce a sufficiency loss to prevent dropping of task-relevant information, thus explicitly preserving the sufficiency of prediction information in the distilled feature.

High Accuracy and Cost-Saving Active Learning 3D WD-UNet for Airway Segmentation

no code implementations9 Oct 2023 Shiyi Wang, Yang Nan, Simon Walsh, Guang Yang

We propose a novel Deep Active Learning (DeepAL) model-3D Wasserstein Discriminative UNet (WD-UNet) for reducing the annotation effort of medical 3D Computed Tomography (CT) segmentation.

Post-COVID Highlights: Challenges and Solutions of AI Techniques for Swift Identification of COVID-19

no code implementations24 Sep 2023 Yingying Fang, Xiaodan Xing, Shiyi Wang, Simon Walsh, Guang Yang

Since the onset of the COVID-19 pandemic in 2019, there has been a concerted effort to develop cost-effective, non-invasive, and rapid AI-based tools.

The Beauty or the Beast: Which Aspect of Synthetic Medical Images Deserves Our Focus?

1 code implementation3 May 2023 Xiaodan Xing, Yang Nan, Federico Felder, Simon Walsh, Guang Yang

Training medical AI algorithms requires large volumes of accurately labeled datasets, which are difficult to obtain in the real world.

Less is More: Unsupervised Mask-guided Annotated CT Image Synthesis with Minimum Manual Segmentations

no code implementations19 Mar 2023 Xiaodan Xing, Giorgos Papanastasiou, Simon Walsh, Guang Yang

To address these issues, in this work, we propose a novel strategy for medical image synthesis, namely Unsupervised Mask (UM)-guided synthesis, to obtain both synthetic images and segmentations using limited manual segmentation labels.

CS$^2$: A Controllable and Simultaneous Synthesizer of Images and Annotations with Minimal Human Intervention

1 code implementation20 Jun 2022 Xiaodan Xing, Jiahao Huang, Yang Nan, Yinzhe Wu, Chengjia Wang, Zhifan Gao, Simon Walsh, Guang Yang

The destitution of image data and corresponding expert annotations limit the training capacities of AI diagnostic models and potentially inhibit their performance.
