In this work, we focus on the partially connected interference network with confidential messages, and study the secure degrees of freedom with no channel state information at the transmitters (CSIT). Prior works on fully connected interference networks with full CSIT have shown that the secure degrees of freedom scales linearly with the number of users. With no CSIT, however, the secure degrees of...
Data shuffling is one of the fundamental building blocks for distributed learning algorithms, that increases the statistical gain for each step of the learning process. In each iteration, different shuffled data points are assigned by a central node to a distributed set of workers to perform local computation, which leads to communication bottlenecks. The focus of this paper is on formalizing and...
Distributed learning platforms for processing large scale data-sets are becoming increasingly prevalent. In typical distributed implementations, a centralized master node breaks the data-set into smaller batches for parallel processing across distributed workers to achieve speed-up and efficiency. Several computational tasks are of sequential nature, and involve multiple passes over the data. At each...
We investigate the optimal power and rate allocation for multilayer transmission using the broadcast approach over a fading amplify-and-forward relay channel. The source uses multilayer source coding with successive refinement where the layers are transmitted using superposition coding at the source with optimal rate and power allocation. The destination applies successive interference cancellation...
In this paper, we consider a fading relay channel where the source uses multilayer source coding with successive refinement. The source layers are transmitted using superposition coding at the source with optimal power allocation. The relay uses the simple half-duplex amplify-and-forward strategy. The destination applies successive interference cancellation after optimally combining the direct and...
In this paper, we consider a fading relay channel where the source uses two layers source coding with successive refinement. The two source layers are transmitted using superposition coding at the source and relay with optimal power allocation, and successive interference cancellation at the receivers (i.e. relay and destination). The power allocation for the two layers at the source and relay is...
