Few-Shot Medical Image Segmentation with Large Kernel Attention

no code implementations27 Jul 2024 Xiaoxiao Wu, Xiaowei Chen, Zhenguo Gao, Shulei QU, Yuanyuan Qiu

To achieve this, we introduce a plug-and-play attention module that dynamically enhances both query and support features, thereby improving the representativeness of the extracted features.

SuDA: Support-based Domain Adaptation for Sim2Real Motion Capture with Flexible Sensors

no code implementations25 May 2024 Jiawei Fang, Haishan Song, Chengxu Zuo, Xiaoxia Gao, Xiaowei Chen, Shihui Guo, Yipeng Qin

Thanks to the high-linearity of flexible sensors, we address this challenge by proposing a novel Sim2Real Mocap solution based on domain adaptation, eliminating the need for labeled data yet achieving comparable accuracy to supervised learning.

Support-Query Prototype Fusion Network for Few-shot Medical Image Segmentation

no code implementations13 May 2024 Xiaoxiao Wu, Zhenguo Gao, Xiaowei Chen, Yakai Wang, Shulei QU, Na Li

Currently, most studies employ a prototype-based approach, in which prototypical networks are used to construct prototypes from the support set, guiding the processing of the query set to obtain the final results.

HB-net: Holistic bursting cell cluster integrated network for occluded multi-objects recognition

1 code implementation18 Oct 2023 Xudong Gao, Xiao Guang Gao, Jia Rong, Xiaowei Chen, Xiang Liao, Jun Chen

Although in high-noise settings, standard CNNs exhibit slightly greater robustness when compared to HB-net models, the models that combine the HB framework and EA mechanism achieve a comparable level of accuracy and resilience to ResNet50, despite having only three convolutional layers and approximately $1/30$ of the parameters.

Distance and Hop-wise Structures Encoding Enhanced Graph Attention Networks

no code implementations6 Dec 2021 Zhiguo Huang, Xiaowei Chen, Bojuan Wang

Numerous works have proven that existing neighbor-averaging Graph Neural Networks cannot efficiently catch structure features, and many works show that injecting structure, distance, position or spatial features can significantly improve performance of GNNs, however, injecting overall structure and distance into GNNs is an intuitive but remaining untouched idea.

Multi-layered Network Exploration via Random Walks: From Offline Optimization to Online Learning

no code implementations9 Jun 2021 Xutong Liu, Jinhang Zuo, Xiaowei Chen, Wei Chen, John C. S. Lui

For the online learning setting, neither the network structure nor the node weights are known initially.

Semantic Borrowing for Generalized Zero-Shot Learning

no code implementations30 Jan 2021 Xiaowei Chen

Generalized zero-shot learning (GZSL) is one of the most realistic but challenging problems due to the partiality of the classifier to supervised classes, especially under the class-inductive instance-inductive (CIII) training setting, where testing data are not available.

Pandemic risk management: resources contingency planning and allocation

no code implementations6 Dec 2020 Xiaowei Chen, Wing Fung Chong, Runhuan Feng, Linfeng Zhang

Repeated history of pandemics, such as SARS, H1N1, Ebola, Zika, and COVID-19, has shown that pandemic risk is inevitable.
