A new algebraic technique for the construction of interactive proof systems is presented. Our technique is used to prove that every language in the polynomial-time hierarchy has an interactive proofâ€¦ (More)

There are two main algorithmic approaches to sparse signal recovery: geometric and combinatorial. The geometric approach utilizes geometric properties of the measurement matrix Phi. A notable exampleâ€¦ (More)

In recent years the MapReduce framework has emerged as one of the most widely used parallel computing platforms for processing data on terabyte and petabyte scales. Used daily at companies such asâ€¦ (More)

We describe a randomized approximation algorithm which takes an instance of MAX 3SAT as input. If the instanceâ€”a collection of clauses each of length at most threeâ€”is satisfiable, then the expectedâ€¦ (More)

In the 0-extension problem, we are given a weighted graph with some nodes marked as terminals and a semi-metric on the set of terminals. Our goal is to assign the rest of the nodes to terminals so asâ€¦ (More)

We study the problem of finding a most profitable subset of n given tasks, each with a given start and finish time as well as profit and resource requirement, that at no time exceeds the quantity Bâ€¦ (More)

Conditional functional dependencies (CFDs) have recently been proposed as a useful integrity constraint to summarize data semantics and identify data inconsistencies. A CFD augments a functionalâ€¦ (More)

We prove that if a linear error-correcting code C:{0, 1} n â†’{0, 1} m is such that a bit of the message can be probabilistically reconstructed by looking at two entries of a corrupted codeword, then mâ€¦ (More)
