Communication-Efficient Gradient Coding for Straggler Mitigation in Distributed Learning
Swanand Kadhe, O. Ozan Koyluoglu, Kannan Ramchandran
Distributed implementations of gradient-based methods, wherein a server distributes gradient computations across worker machines, need to overcome two limitations: delays caused by…
On an Equivalence Between Single-Server PIR with Side Information and Locally Recoverable Codes
Swanand Kadhe, Anoosheh Heidarzadeh, Alex Sprintson +1
Private Information Retrieval (PIR) problem has recently attracted a significant interest in the information-theory community. In this problem, a user wants to privately download o…
Gradient Coding Based on Block Designs for Mitigating Adversarial Stragglers
Swanand Kadhe, O. Ozan Koyluoglu, Kannan Ramchandran
Distributed implementations of gradient-based methods, wherein a server distributes gradient computations across worker machines, suffer from slow running machines, called 'straggl…
Vulnerabilities of Massive MIMO Systems Against Pilot Contamination Attacks
Berk Akgun, Marwan Krunz, O. Ozan Koyluoglu
We consider a single-cell massive MIMO system in which a base station (BS) with a large number of antennas transmits simultaneously to several single-antenna users in the presence…
Joint secrecy over the K-Transmitter Multiple Access Channel
Yanling Chen, O. Ozan Koyluoglu, A. J. Han Vinck
This paper studies the problem of secure communication over a K-transmitter multiple access channel in the presence of an external eavesdropper, subject to a joint secrecy constrai…
Architecture-aware Coding for Distributed Storage: Repairable Block Failure Resilient Codes
Gokhan Calis, O. Ozan Koyluoglu
In large scale distributed storage systems (DSS) deployed in cloud computing, correlated failures resulting in simultaneous failure (or, unavailability) of blocks of nodes are comm…
