Combinatorial Message Sharing and a New Achievable Region for Multiple Descriptions
Kumar Viswanatha, Emrah Akyol, Kenneth Rose
This paper presents a new achievable rate-distortion region for the general L channel multiple descriptions problem. A well known general region for this problem is due to Venkatar…
The Lossy Common Information of Correlated Sources
Kumar Viswanatha, Emrah Akyol, Kenneth Rose
The two most prevalent notions of common information (CI) are due to Wyner and Gacs-Korner and both the notions can be stated as two different characteristic points in the lossless…
On Zero Delay Source-Channel Coding
Emrah Akyol, Kumar Viswanatha, Kenneth Rose +1
In this paper, we study the zero-delay source-channel coding problem, and specifically the problem of obtaining the vector transformations that optimally map between the m-dimensio…
On Large Scale Distributed Compression and Dispersive Information Routing for Networks
Kumar Viswanatha, Sharadh Ramaswamy, Ankur Saxena +2
This paper considers the problem of distributed source coding for a large network. A major obstacle that poses an existential threat to practical deployment of conventional approac…
Minimum Communication Cost for Joint Distributed Source Coding and Dispersive Information Routing
Kumar Viswanatha, Emrah Akyol, Kenneth Rose
This paper considers the problem of minimum cost communication of correlated sources over a network with multiple sinks, which consists of distributed source coding followed by rou…
Subset Typicality Lemmas and Improved Achievable Regions in Multiterminal Source Coding
Kumar Viswanatha, Emrah Akyol, Kenneth Rose
Consider the following information theoretic setup wherein independent codebooks of N correlated random variables are generated according to their respective marginals. The problem…
