WebApr 28, 2024 · Parallel incoherent matrix computing can be achieved by controlling the resonant states of MRRs, which is commonly used in optical tensor computing and ONNs [ 11, 37 ]. The problem of MRR arrays is that the computation is incoherent, which means MRR arrays can only perform amplitude modulation without phase information. 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…

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 ...
