GQFedWAvg: Optimization-Based Quantized Federated Learning in General Edge Computing Systems

1 code implementation13 Jun 2023 Yangchen Li, Ying Cui, Vincent Lau

In this paper, we propose an optimization-based quantized FL algorithm, which can appropriately fit a general edge computing system with uniform or nonuniform computing and communication resources at the workers.

An Optimization Framework for Federated Edge Learning

no code implementations26 Nov 2021 Yangchen Li, Ying Cui, Vincent Lau

To explore the full potential of FL in such an edge computing system, we first present a general FL algorithm, namely GenQSGD, parameterized by the numbers of global and local iterations, mini-batch size, and step size sequence.

Sample-based and Feature-based Federated Learning for Unconstrained and Constrained Nonconvex Optimization via Mini-batch SSCA

1 code implementation13 Apr 2021 Ying Cui, Yangchen Li, Chencheng Ye

We show that the proposed FL algorithms converge to stationary points and Karush-Kuhn-Tucker (KKT) points of the respective unconstrained and constrained nonconvex problems, respectively.
