Breaking the Communication-Privacy-Accuracy Tradeoff with $f$-Differential Privacy

no code implementations NeurIPS 2023 Richeng Jin, Zhonggen Su, Caijun Zhong, Zhaoyang Zhang, Tony Quek, Huaiyu Dai

We consider a federated data analytics problem in which a server coordinates the collaborative data analysis of multiple users with privacy concerns and limited communication capability.

Over-the-Air Split Machine Learning in Wireless MIMO Networks

no code implementations7 Oct 2022 Yuzhi Yang, Zhaoyang Zhang, Yuqing Tian, Zhaohui Yang, Chongwen Huang, Caijun Zhong, Kai-Kit Wong

In such a split ML system, the precoding and combining matrices are regarded as trainable parameters, while MIMO channel matrix is regarded as unknown (implicit) parameters.

C-GRBFnet: A Physics-Inspired Generative Deep Neural Network for Channel Representation and Prediction

no code implementations5 Dec 2021 Zhuoran Xiao, Zhaoyang Zhang, Chongwen Huang, Xiaoming Chen, Caijun Zhong, Mérouane Debbah

Specifically, we first use a forward deep neural network to infer the positions of all possible images of the source reflected by the surrounding scatterers within that environment, and then use the well-known Gaussian Radial Basis Function network (GRBF) to approximate the amplitudes of all possible propagation paths.

Accelerating Federated Edge Learning via Optimized Probabilistic Device Scheduling

no code implementations24 Jul 2021 Maojun Zhang, Guangxu Zhu, Shuai Wang, Jiamo Jiang, Caijun Zhong, Shuguang Cui

Building on the analytical result, an optimized probabilistic scheduling policy is derived in closed-form by solving the approximate communication time minimization problem.

Intelligent Reflecting Surface Aided Multicasting with Random Passive Beamforming

no code implementations1 Sep 2020 Qin Tao, Shuowen Zhang, Caijun Zhong, Rui Zhang

For the proposed scheme, we first derive a closed-form approximation of the outage probability, based on which the optimal $Q$ with best outage performance can be efficiently obtained.
