Privacy Amplification for Federated Learning via User Sampling and Wireless Aggregation

1 code implementation2 Mar 2021 Mohamed Seif, Wei-Ting Chang, Ravi Tandon

Specifically, the central DP privacy leakage has been shown to scale as $\mathcal{O}(1/K^{1/2})$, where $K$ is the number of users.

Communication Efficient Federated Learning over Multiple Access Channels

no code implementations23 Jan 2020 Wei-Ting Chang, Ravi Tandon

In particular, we focus on the design of digital gradient transmission schemes over a MAC, where gradients at each user are first quantized, and then transmitted over a MAC to be decoded individually at the PS.
