矩陣分解（rank decomposition）

本文收集了現有矩陣分解的幾乎所有算法和應用，原文鏈接：https://sites.google.com/site/igorcarron2/matrixfactorizations

Matrix Decompositions?has a long history and generally centers around a set of known factorizations such as LU, QR, SVD and eigendecompositions. More?recent factorizations have seen the light of the day with work started with the advent of NMF, k-means and related algorithm?[1]. However, with the advent of new methods based on random projections and convex optimization that started in part in the?compressive sensing literature, we are seeing another surge of very diverse algorithms dedicated to many different kinds of?matrix factorizations?with new constraints based on rank and/or positivity and/or sparsity,… As a result of this large increase in interest, I have decided to keep a list of them here following the success of the?big picture in compressive sensing.

The sources for this list include?the following most excellent sites:?Stephen Becker’s page,?Raghunandan H. Keshavan‘ s?page,?Nuclear Norm and Matrix Recovery?through SDP by?Christoph Helmberg,?Arvind Ganesh‘s?Low-Rank Matrix Recovery and Completion via Convex Optimization?who provide more in-depth additional information.??Additional codes were featured also on?Nuit Blanche. The following people provided additional inputs:?Olivier Grisel,?Matthieu Puigt.

Most of the algorithms listed below generally rely on using the nuclear norm as a proxy to the rank functional.?It may not be optimal. Currently,?CVX?(?Michael Grant?and?Stephen ?Boyd) consistently allows one to explore other proxies for the rank functional such as the?log-det?as found by?Maryam ?Fazell,?Haitham Hindi,?Stephen Boyd.?** is used to show that the algorithm uses another heuristic than the nuclear norm.

In terms of notations, A refers to a matrix, L refers to a low rank matrix, S a sparse one and N to a noisy one. This page lists the different codes that implement the following matrix factorizations:?Matrix Completion,?Robust PCA?, Noisy?Robust PCA,?Sparse PCA,?NMF,?Dictionary Learning,?MMV,?Randomized Algorithms and other factorizations. Some of these toolboxes can sometimes implement several of these decompositions and are listed accordingly. Before I list algorithm here, I generally feature them on Nuit Blanche under the MF tag:?http://nuit-blanche.blogspot.com/search/label/MF?or.?you can also subscribe to the Nuit Blanche feed,

Matrix Completion, A = H.*L with H a known mask,?L unknown?solve for?L lowest rank possible

The idea of this approach is to complete the unknown coefficients of a matrix based on the fact that the matrix is low rank:
