Codes Correcting Burst and Arbitrary Erasures for Reliable and Low-Latency Communication

Serge Kas Hanna, Zhiyuan Tan, Wen Xu, Antonia Wachter-Zeh

ICASSP 2023accepted

Motivated by modern network communication applications which require low latency, we study codes that correct erasures with low decoding delay. We provide a simple explicit construction that yields convolutional codes that can correct both burst and arbitrary erasures under a maximum decoding delay…

Adaptive Distributed Stochastic Gradient Descent for Minimizing Delay in the Presence of Stragglers

Serge Kas Hanna, Rawad Bitar, Parimal Parag, Venkat Dasari, Salim El Rouayheb

ICASSP 2020accepted

We consider the setting where a master wants to run a distributed stochastic gradient descent (SGD) algorithm on n workers each having a subset of the data. Distributed SGD may suffer from the effect of stragglers, i.e., slow or unresponsive workers who cause delays. One solution studied in the lite…
