Strengthening Recursive Constructions for Zero-Error Shannon Capacity
Ravi Tandon
The exact Shannon capacity is unknown for every odd cycle beyond the five-cycle , making odd cycles a central open problem in zero-error information theory. Improving the know…
FAID Diversity via Neural Networks
Xin Xiao, Nithin Raveendran, Bane Vasic +2
Decoder diversity is a powerful error correction framework in which a collection of decoders collaboratively correct a set of error patterns otherwise uncorrectable by any individu…
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…
Asymmetric Leaky Private Information Retrieval
Islam Samy, Mohamed A. Attia, Ravi Tandon +1
Information-theoretic formulations of the private information retrieval (PIR) problem have been investigated under a variety of scenarios. Symmetric private information retrieval (…
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…
Latent-variable Private Information Retrieval
Islam Samy, Mohamed A. Attia, Ravi Tandon +1
In many applications, content accessed by users (movies, videos, news articles, etc.) can leak sensitive latent attributes, such as religious and political views, sexual orientatio…
