Cache-Aided Combination Networks with Interference
Ahmed Roushdy, Abolfazl Seyed Motahari, Mohammed Nafie +1
Centralized coded caching and delivery is studied for a radio access combination network (RACN), whereby a set of edge nodes (ENs), connected to a cloud server via orthogonal f…
SparseCast: Hybrid Digital-Analog Wireless Image Transmission Exploiting Frequency Domain Sparsity
Tze-Yang Tung, Deniz Gündüz
A hybrid digital-analog wireless image transmission scheme, called SparseCast, is introduced, which provides graceful degradation with channel quality. SparseCast achieves improved…
Distributed Gradient Descent with Coded Partial Gradient Computations
Emre Ozfatura, Sennur Ulukus, Deniz Gunduz
Coded computation techniques provide robustness against straggling servers in distributed computing, with the following limitations: First, they increase decoding complexity. Secon…
Speeding Up Distributed Gradient Descent by Utilizing Non-persistent Stragglers
Emre Ozfatura, Deniz Gunduz, Sennur Ulukus
Distributed gradient descent (DGD) is an efficient way of implementing gradient descent (GD), especially for large data sets, by dividing the computation tasks into smaller subtask…
Computation Scheduling for Distributed Machine Learning with Straggling Workers
Mohammad Mohammadi Amiri, Deniz Gunduz
We study scheduling of computation tasks across n workers in a large scale distributed learning problem with the help of a master. Computation and communication delays are assumed…
Deep Joint Source-Channel Coding for Wireless Image Transmission
Eirina Bourtsoulatze, David Burth Kurka, Deniz Gunduz
We propose a joint source and channel coding (JSCC) technique for wireless image transmission that does not rely on explicit codes for either compression or error correction; inste…
