WebIncoherence-Optimal Matrix Completion Yudong Chen EECS, UC Berkeley [email protected] Abstract This paper considers the matrix completion problem. We show that it is not necessary to ... optimal with respect to the incoherence parameter (as well as to the rank rand the matrix dimension n, except for a lognfactor). As … WebWe consider the matrix completion problem under a form of row/column weighted entrywise sampling, including the case of uniform entrywise sampling as a special case. We analyze the associated random observation operator, and prove that with high probability, it satisfies a form of restricted strong convexity with respect to weighted Frobenius norm.

WebDec 1, 2011 · If the underlying matrix satisfies a certain incoherence condition, then the number of entries required is equal to a quadratic logarithmic factor times the number of parameters in the singular value decomposition. The proof of this assertion is short, self contained, and uses very elementary analysis. WebAbstract: 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 similar questions in collaborative filtering.
