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… WebThe coherence of a matrix is deﬁned as the maximum absolute value of inner products between any two distinct normalized columns. A matrix with small coherence is termed as an incoherent matrix.

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 $\eta (M)=\frac{n}{r}$ ⁠ . Webmatrix Xn. A matrix is incoherent when L˜ n is small. See, for example, Donoho, Elad and Temlyakov (2006). With slight abuse of terminology, in this paper we shall call both Ln and L˜ n coherence of the random matrix Xn, the former for the case μ is unknown and the latter for the case μ is known.
