Coding for Network Coding
Sparse graph codes probabilistic channel models Shannon channel capacity network coding
2015/8/20
We consider communication over a noisy network under randomized linear network coding. Possible error mechanism include node- or link- failures, Byzantine behavior of nodes, or an over-estimate of the...
We consider a class of decentralized team decision problems with non classical information structure and discrete state spaces. In general, decentralized team decision problems are NP-complete. In thi...
Hat Guessing Games and the Use of Coding for Decentralized Control
Decentralized Control Games
2015/6/19
We study a class of decentralized team decision problems over discrete state spaces with non classical information structures. We present a simple class of problems, where an optimal solution can be o...
Single Nucleotide Polymorphism in the Coding Region of Bovine Chemerin Gene and Their Associations with Carcass Traits in Japanese Black Cattle
Japanese Black Cattle Chemerin Single Nucleotide Polymorphism Carcass Trait
2016/5/18
Chemerin, highly expressed in adipose and liver tissues, regulates glucose and lipid metabolism and immunity in these tissues in ruminants and mice. Our previous reports showed that chemerin is involv...
THE EXTENDED-OCTREE SPHEROID SUBDIVISION AND CODING MODEL
extended-Octree model global spatial grid, spheroid grid, grid subdivision grid coding spatial data model
2014/4/21
Discrete Global Grid has been widely used as the basic data model of digital earth. But it is only confined to the earth surface, and it
can not reach to the earth inside or outside. The extended-Oc...
In this paper we discuss a novel framework for multiclass learning, defined by a suitable coding/decoding strategy, namely the simplex coding, that allows to generalize to multiple classes a relaxatio...
Coding Scheme for Optimizing Random I/O Performance
Coding Scheme Optimizing Random I/O Performance
2012/3/1
Flash memories intended for SSD and mobile applications need to provide high random I/O performance. This requires using efficient schemes for reading small chunks of data (e.g. 0.5KB - 4KB) from rand...
Delay-limited Source and Channel Coding of Quasi-Stationary Sources over Block Fading Channels: Design and Scaling Laws
Outage capacity quasi-stationary source outage distortion source and channel coding
2012/2/29
In this paper, delay-limited transmission of quasi-stationary sources over block fading channels are considered. Considering distortion outage probability as the performance measure, two source and ch...
Applications of Derandomization Theory in Coding
Derandomization theory randomness extractors pseudorandomness wiretap channels group testing error-correcting codes
2011/10/9
Abstract: Randomized techniques play a fundamental role in theoretical computer science and discrete mathematics, in particular for the design of efficient algorithms and construction of combinatorial...
Abstract: We describe a novel extension of subspace codes for noncoherent networks, suitable for use when the network is viewed as a communication system that introduces both dimension and symbol erro...
Non-equilibrium Information Envelopes and the Capacity-Delay-Error-Tradeoff of Source Coding
Non-equilibrium Information Envelopes Capacity-Delay-Error-Tradeoff Source Coding Information Theory
2011/10/8
Abstract: This paper develops an envelope-based approach to establish a link between information and queueing theory. Unlike classical, equilibrium information theory, information envelopes focus on t...
Linear Index Coding via Semidefinite Programming
Linear Index Coding Semidefinite Programming Data Structures and Algorithms
2011/9/30
Abstract: In the index coding problem, introduced by Birk and Kol (INFOCOM, 1998), the goal is to broadcast an n bit word to n receivers (one bit per receiver), where the receivers have side informati...
Interference Networks with General Message Sets: A Random Coding Scheme
Interference Networks General Message Sets Broadcast Channel Mutiple Access Channel
2011/8/31
Abstract: In this paper, the Interference Network with General Message Sets (IN-GMS) is introduced in which several transmitters send messages to several receivers: Each subset of transmitters transmi...
Abstract: The last decades have seen a growing interest in hash functions that allow some sort of tolerance, e.g. for the purpose of biometric authentication. Among these, the syndrome fuzzy hashing c...
Abstract: A sender wishes to broadcast an n character word x in F^n (for a field F) to n receivers R_1,...,R_n. Every receiver has some side information on x consisting of a subset of the characters o...
