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 WebTherefore, non-uniform sampling is commonly adopted to accelerate data acquisition and then the complete spectrum can be obtained by reconstruction method. At present, the state-of-the-art reconstruction methods are based on the idea of low-rank Hankel matrix completion and solved by different singular value thresholding methods. simpson parole hearing
