Establishing Rigorous and Cost-effective Clinical Trials for Artificial Intelligence Models

1 code implementation11 Jul 2024 Wanling Gao, Yunyou Huang, Dandan Cui, Zhuoming Yu, Wenjing Liu, Xiaoshuang Liang, Jiahui Zhao, Jiyue Xie, Hao Li, Li Ma, Ning Ye, Yumiao Kang, Dingfeng Luo, Peng Pan, Wei Huang, Zhongmou Liu, Jizhong Hu, Gangyuan Zhao, Chongrong Jiang, Fan Huang, Tianyi Wei, Suqin Tang, Bingjie Xia, Zhifei Zhang, Jianfeng Zhan

We envision DC-AI RCTs and VC-MedAI as pivotal advancements, presenting innovative and transformative evaluation methodologies for AI models in clinical practice, offering a preclinical-like setting mirroring conventional medicine, and reshaping development paradigms in a cost-effective and fast-iterative manner.

Addressing Class Variable Imbalance in Federated Semi-supervised Learning

no code implementations21 Mar 2023 Zehui Dong, Wenjing Liu, Siyuan Liu, Xingzhi Chen

Most of the current research is focusing on class imbalance with a fixed number of classes, while little attention is paid to data imbalance with a variable number of classes.

An Efficient Ratio Detector for Ambient Backscatter Communication

no code implementations18 Oct 2022 Wenjing Liu, Shanpu Shen, Danny H. K. Tsang, Ranjan K. Mallik, Ross Murch

Different from original ratio detectors that use the magnitude ratio of the signals between two Reader antennas, in our proposed approach, we utilize the complex ratio so that phase information is preserved and propose an accurate linear channel model approximation.

A Random Algorithm for Profit Maximization with Multiple Adoptions in Online Social Networks

Enhancing Ambient Backscatter Communication Utilizing Coherent and Non-Coherent Space-Time Codes

no code implementations14 Sep 2020 Wenjing Liu, Shanpu Shen, Danny H. K. Tsang, Ross Murch

To overcome this challenge, we propose the use of orthogonal space-time block codes (OSTBC) by incorporating multiple antennas at the Tag as well as at the Reader.
