Abstract: Completing a matrix from a small subset of its entries, i.e., matrix completion is a challenging problem arising from many real-world applications, such as machine learning and computer ...

Abstract: To solve the problem that Direction of Arrival(DOA) estimation based on virtual array interpolation does not fully utilize covariance matrix information, the reconstruction of covariance ...

are the eigenvalues of in decreasing order. If, then and the spectral decomposition (1.2) coincides with the SVD of. In this case the solution of (1.1) is given by the Eckart-Young-Mirsky theorem. See ...

Low-rank matrix recovery problem is difficult due to its non-convex properties and it is usually solved using convex relaxation approaches. In this paper, we formulate the non-convex low-rank matrix ...
