Over-the-Air Computation Empowered Federated Learning: A Joint Uplink-Downlink Design
Deyou Zhang, Ming Xiao, Mikael Skoglund
In this paper, we investigate the communication designs of over-the-air computation (AirComp) empowered federated learning (FL) systems considering uplink model aggregation and dow…
Federated Learning via Active RIS Assisted Over-the-Air Computation
Deyou Zhang, Ming Xiao, Mikael Skoglund +1
In this paper, we propose leveraging the active reconfigurable intelligence surface (RIS) to support reliable gradient aggregation for over-the-air computation (AirComp) enabled fe…
NOMA Enabled Multi-Access Edge Computing: A Joint MU-MIMO Precoding and Computation Offloading Design
Deyou Zhang, Meng Wang, Shuo Shi +1
This letter investigates computation offloading and transmit precoding co-design for multi-access edge computing (MEC), where multiple MEC users (MUs) equipped with multiple antenn…
IRS Assisted Federated Learning A Broadband Over-the-Air Aggregation Approach
Deyou Zhang, Ming Xiao, Zhibo Pang +2
We consider a broadband over-the-air computation empowered model aggregation approach for wireless federated learning (FL) systems and propose to leverage an intelligent reflecting…
