Incoherence-optimal matrix completion
WebNear-Optimal Matrix Completion Emmanuel J. Candès, Associate Member, IEEE, and Terence Tao Abstract—This paper is concerned with the problem of recov-ering 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 Webincoherence, is a natural and necessary requirement; it prevents the information of the row and column spaces of the matrix from being too concentrated in a few rows or columns. …
