Decentralized Federated Learning via MIMO Over-the-Air Computation: Consensus Analysis and Performance Optimization
Zhiyuan Zhai, Xiaojun Yuan, Xin Wang
Decentralized federated learning (DFL), inherited from distributed optimization, is an emerging paradigm to leverage the explosively growing data from wireless devices in a fully d…
PlankAssembly: Robust 3D Reconstruction from Three Orthographic Views with Learnt Shape Programs
Wentao Hu, Jia Zheng, Zixin Zhang +3
In this paper, we develop a new method to automatically convert 2D line drawings from three orthographic views into 3D CAD models. Existing methods for this problem reconstruct 3D…
Over-the-Air Federated Learning in MIMO Cloud-RAN Systems
Haoming Ma, Xiaojun Yuan, Zhi Ding
To address the limitations of traditional over-the-air federated learning (OA-FL) such as limited server coverage and low resource utilization, we propose an OA-FL in MIMO cloud ra…
Energy-Efficient UAV Communications in the Presence of Wind: 3D Modeling and Trajectory Design
Xinhong Dai, Bin Duo, Xiaojun Yuan +1
The rapid development of unmanned aerial vehicle (UAV) technology provides flexible communication services to terrestrial nodes. Energy efficiency is crucial to the deployment of U…
