Election Coding for Distributed Learning: Protecting SignSGD against Byzantine Attacks
Jy-yong Sohn, Dong-Jun Han, Beongjun Choi +1
Recent advances in large-scale distributed learning algorithms have enabled communication-efficient training via SignSGD. Unfortunately, a major issue continues to plague distribut…
Coded Matrix Multiplication on a Group-Based Model
Muah Kim, Jy-yong Sohn, Jaekyun Moon
Coded distributed computing has been considered as a promising technique which makes large-scale systems robust to the "straggler" workers. Yet, practical system models for distrib…
Coded Distributed Computing over Packet Erasure Channels
Dong-Jun Han, Jy-yong Sohn, Jaekyun Moon
Coded computation is a framework which provides redundancy in distributed computing systems to speed up largescale tasks. Although most existing works assume an error-free scenario…
Bi-Directional Cooperative NOMA without Full CSIT
Minseok Choi, Dong-Jun Han, Jaekyun Moon
In this paper, we propose bi-directional cooperative non-orthogonal multiple access (NOMA). Compared to conventional NOMA, the main contributions of bi-directional cooperative NOMA…
A Class of MSR Codes for Clustered Distributed Storage
Jy-yong Sohn, Beongjun Choi, Jaekyun Moon
Clustered distributed storage models real data centers where intra- and cross-cluster repair bandwidths are different. In this paper, exact-repair minimum-storage-regenerating (MSR…
On Reusing Pilots Among Interfering Cells in Massive MIMO
Jy-yong Sohn, Sung Whan Yoon, Jaekyun Moon
Pilot contamination, caused by the reuse of pilots among interfering cells, remains as a significant obstacle that limits the performance of massive multi-input multi-output antenn…
