Incoherence property

WebIn linear algebra, the restricted isometry property (RIP) characterizes matrices which are nearly orthonormal, at least when operating on sparse vectors. The concept was introduced by Emmanuel Candès and Terence Tao and is used to prove many theorems in the field of compressed sensing. There are no known large matrices with bounded restricted … WebIncoherence property: We may take the coherence parameter (F)to be the smallest number such that with a=(a[1];:::;a[n])∼F, max 1≤t≤n Sa[t]S2 ≤ (F) (1.5) holds either deterministically or stochastically in the sense discussed below. The smaller (F), i.e. the more incoherent the sensing vectors, the fewer samples we need for accurate

WebFeb 15, 2024 · The incoherence and isotropy properties together guarantee that sparse vectors lie away from the nullspace of the sensing matrix. The role of the isotropy condition is to keep the measurement matrix from being rank deficient when sufficiently many measurements are taken. WebCoherence is an ideal property of waves that enables stationary (i.e., temporally or spatially constant) interference. It contains several distinct concepts, which are limiting cases that never quite occur in reality but … WebDec 8, 2024 · While working on an exercise, I stumbled upon the term mutual incoherence of a matrix.
