The Power of Convex Relaxation: Near-Optimal Matrix Completion [PDF]

open access: yesIEEE Transactions on Information Theory, 2009
This paper is concerned with the problem of recovering an unknown matrix from a small fraction of its entries. This is known as the matrix completion problem, and comes up in a great number of applications, including the famous Netflix Prize and other ...

On the Theory of Relaxation [PDF]

open access: yesProceedings of the Glasgow Mathematical Association, 1953
§ 1. When a numerical method of obtaining an approximate solution of a linear differential equation is employed, the process involves two distinct types of approximation. The region of integration having been covered with a regular net, the differential equation and the appropriate boundary conditions are replaced by finite difference equations which ...
