Privacy Amplification for Federated Learning via User Sampling and Wireless Aggregation
Mohamed Seif, Wei-Ting Chang, Ravi Tandon
In this paper, we study the problem of federated learning over a wireless channel with user sampling, modeled by a Gaussian multiple access channel, subject to central and local di…
When Classical Chinese Meets Machine Learning: Explaining the Relative Performances of Word and Sentence Segmentation Tasks
Chao-Lin Liu, Chang-Ting Chu, Wei-Ting Chang +1
We consider three major text sources about the Tang Dynasty of China in our experiments that aim to segment text written in classical Chinese. These corpora include a collection of…
Communication Efficient Federated Learning over Multiple Access Channels
Wei-Ting Chang, Ravi Tandon
In this work, we study the problem of federated learning (FL), where distributed users aim to jointly train a machine learning model with the help of a parameter server (PS). In ea…
Cache-Aided Content Delivery in Fog-RAN Systems with Topological Information and no CSI
Wei-Ting Chang, Ravi Tandon, Osvaldo Simeone
In this work, we consider a Fog Radio Access Network (F-RAN) system with a partially connected wireless topology and no channel state information available at the cloud and Edge No…
On the Upload versus Download Cost for Secure and Private Matrix Multiplication
Wei-Ting Chang, Ravi Tandon
In this paper, we study the problem of secure and private distributed matrix multiplication. Specifically, we focus on a scenario where a user wants to compute the product of a con…
Random Sampling for Distributed Coded Matrix Multiplication
Wei-Ting Chang, Ravi Tandon
Matrix multiplication is a fundamental building block for large scale computations arising in various applications, including machine learning. There has been significant recent in…
