WebThere is an incoherence property μ used in CS to measure the correlation between the sensing and representation bases; whereby low correlation enables signal reconstruction … WebBoth of these incoherence properties are used to stipulate the minimum number of samples required to reconstruct a signal (1D, 2D, respectively). However, I cannot see where the matrix incoherence property addresses the nature of the sampling; I.e. it only tells me which matrices are more likely to be reconstructed.

Various matrix completion algorithms have been proposed. These includes convex relaxation-based algorithm, gradient-based algorithm, and alternating minimization-based algorithm. The rank minimization problem is NP-hard. One approach, proposed by Candès and Recht, is to form a convex relaxation of the problem and minimize the nuclear norm (which gives the sum of the singular values of ) instead of (which counts the number of non zero singular values of ). This is an… Webwhere the precision matrix is the superposition of a sparse matrix and a low-rank matrix.
