Improved Nearly-MDS Expander Codes
A construction of expander codes is presented with the following three properties: (i) the codes lie close to the Singleton bound, (ii) they can be encoded in time complexity that ...

Unbalanced Expanders and Randomness Extractors from Parvaresh-Vardy Codes
We give an improved explicit construction of highly unbalanced bipartite expander graphs with expansion arbitrarily close to the degree (which is polylogarithmic in the number of ...

Guessing Facets: Polytope Structure and Improved LP Decoder
Abstract--We investigate the structure of the polytope underlying the linear programming (LP) decoder introduced by Feldman, Karger, and Wainwright. We first show that for expander...

PathExpander: Architectural Support for Increasing the Path Coverage of Dynamic Bug Detection
Dynamic software bug detection tools are commonly used because they leverage run-time information. However, they suffer from a fundamental limitation, the Path Coverage Problem: t...
