Principal Component Pursuit with Reduced Linear Measurements
Principal Component Pursuit Reduced Linear Measurements low-rank matrix sparse matrix
2012/3/1
In this paper, we study the problem of decomposing a superposition of a low-rank matrix and a sparse matrix when a relatively few linear measurements are available. This problem arises in many data pr...

摘要 The principal component analysis (PCA) is one of the most celebrated methods in analysing multivariate data. An effort of extending PCA is projection pursuit (PP), a more general class of dimension...
