WebAssuming x is sparse (which is not wrong in many cases), makes things easier. So let's say our observed data is y, and we want to get x. The problem is then: x = argmin { L2 [ S (F (x)) - y ] + λ * L1 [x] } where S is a sampling function, F is the fourier transform, x is the sparse vector, y is the response from the telescope, L2 and L1 are 1 ... http://www.stat.columbia.edu/%7Ediego/PapersandDraft/MatrixCompletion.pdf

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…

WebFeb 1, 2024 · Loosely speaking, a coherent matrix is ‘spiky’, whereas an incoherent matrix is ‘diffuse’ with respect to the distribution of the magnitudes of its entries. For example, if M [1, 1] = 1 is the only non-zero entry of M , then M is extremely coherent since $\eta (M)=\frac{n}{r}$ ⁠ .
