Incoherence property
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 of sparse signals with fewer samples and high correlation makes it nearly impossible regardless of the sparsity of the signal.

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 WebWe will say that the matrix obeys the strong incoherence property with parameter if one can take and both less than or equal to (this property is related to, but slightly dif-ferent from, the incoherence property, which will be discussed in Section I-F1).

WebApr 24, 2024 · The literature on compressive sensing (CS) frequently notes that CS relies on two principles: sparsity and incoherence. While I understand why the signal of interest should be sparse in some domain since CS relies on minimizing the norm, incoherence is much fuzzier to me. chinese company skynetWebThe concept of incoherence arose in compressed sensing. It is introduced in the context of matrix completion to ensure the singular vectors of are not too "sparse" in the sense that all coordinates of each singular vector are of comparable magnitude instead of just a few coordinates having significantly larger magnitudes. grandforks craiglist noleaks mowerWebDefine incoherence. incoherence synonyms, incoherence pronunciation, incoherence translation, English dictionary definition of incoherence. n. 1.
