Denoising based Vector Approximate Message Passing
The D-AMP methodology, recently proposed by Metzler, Maleki, and Baraniuk, allows one to plug in sophisticated denoisers like BM3D into the AMP algorithm to achieve state-of-the-art compressive image recovery. But AMP diverges with small deviations from the i.i.d.-Gaussian assumption on the measurement matrix. Recently, the VAMP algorithm has been proposed to fix this problem. In this work, we ...
متن کاملApproximate Message Passing
In this note, I summarize Sections 5.1 and 5.2 of Arian Maleki’s PhD thesis. 1 Notation We denote scalars by small letters e.g. a, b, c, . . ., vectors by boldface small letters e.g. λ,α,x, . . ., matrices by boldface capital letter e.g. A,B,C, . . ., (subsets of) natural numbers by capital letters e.g. N,M, . . .. We denote i’th element of a vector a by ai and (i, j)’th entry of a matrix A by ...
متن کاملHybrid Vector Perturbation Precoding: The Blessing of Approximate Message Passing
Vector perturbation (VP) precoding is a promising technique for multiuser communication systems operating in the downlink. In this work, we introduce a hybrid framework to improve the performance of lattice reduction (LR) aided (LRA) VP. Firstly, we perform a simple precoding using zero forcing (ZF) or successive interference cancellation (SIC) based on a reduced lattice basis. Since the signal...
متن کاملParameterless Optimal Approximate Message Passing
Iterative thresholding algorithms are well-suited for high-dimensional problems in sparse recovery and compressive sensing. The performance of this class of algorithms depends heavily on the tuning of certain threshold parameters. In particular, both the final reconstruction error and the convergence rate of the algorithm crucially rely on how the threshold parameter is set at each step of the ...
متن کاملBilinear Generalized Approximate Message Passing
We extend the generalized approximate message passing (G-AMP) approach, originally proposed for highdimensional generalized-linear regression in the context of compressive sensing, to the generalized-bilinear case, which enables its application to matrix completion, robust PCA, dictionary learning, and related matrix-factorization problems. In the first part of the paper, we derive our Bilinear...
