Incoherence matrix
Webproposed algorithm for two scenarios: matrix completion under Assumption 1, and matrix comple-tion under both Assumption 1 and Assumption 2. Furthermore, we will assume that Assumption 1 always holds, and that the rank k, the condition number ˙ 1 =˙ k, and the incoherence parameter 0 of the matrix Mare bounded from above by a constant, as n!1. WebIn quantum scattering, the interaction between the scattered photons and the superposed target body will cause them to be entangled, thereby delocalizing the phase coherence from the target body to the whole system, rendering the interference pattern unobservable.

WebIncoherence-Optimal Matrix Completion. Abstract: This paper considers the matrix completion problem. We show that it is not necessary to assume joint incoherence, which … WebIn order to meet practical requirements, the measurement matrix are generally expected to have the following properties: (1) The strong incoherence between measurement and sparse basis; (2) the number of measurements for perfect reconstruction is close to the theo-retical bound; (3) fast sampling and reconstruction; (4) low memory space and ...
WebApr 14, 2024 · GB-SAR is a kind of imaging radar that obtains a high resolution 2D image of surface, which is presented by a matrix of pixels. To select pixels with stable phase and strong backscattering, a combined permanent scatterer selection (CPSS) method based on signal amplitude and phase information is used to measure the deformation of GB-SAR …
