A Fast and Accurate Failure Frequency Approximation for -Terminal Reliability Systems
Anoosheh Heidarzadeh, Alex Sprintson, Chanan Singh
This paper considers the problem of approximating the failure frequency of large-scale composite -terminal reliability systems. In such systems, the nodes ( of which are term…
Universally Weakly Secure Coset Coding Schemes for Minimum Storage Regenerating (MSR) Codes
Swanand Kadhe, Alex Sprintson
We consider the problem of designing codes for distributed storage that protect user data against eavesdroppers that can gain access to network links as well as individual nodes. O…
Private Information Retrieval with Side Information
Swanand Kadhe, Brenden Garcia, Anoosheh Heidarzadeh +2
We study the problem of Private Information Retrieval (PIR) in the presence of prior side information. The problem setup includes a database of independent messages possibly re…
Codes with Locality in the Rank and Subspace Metrics
Swanand Kadhe, Salim El Rouayheb, Iwan Duursma +1
We extend the notion of locality from the Hamming metric to the rank and subspace metrics. Our main contribution is to construct a class of array codes with locality constraints in…
Successive Local and Successive Global Omniscience
Anoosheh Heidarzadeh, Alex Sprintson
This paper considers two generalizations of the cooperative data exchange problem, referred to as the successive local omniscience (SLO) and the successive global omniscience (SGO)…
An Algebraic-Combinatorial Proof Technique for the GM-MDS Conjecture
Anoosheh Heidarzadeh, Alex Sprintson
This paper considers the problem of designing maximum distance separable (MDS) codes over small fields with constraints on the support of their generator matrices. For any given $m…
