Candes, E. J.,\nLi, X., Ma, Y., & Wright, J. (2011). Robust principal component\nanalysis?. Journal of the ACM (JACM), 58(3), 11. prove that we\ncan recover each component individually under some suitable\nassumptions. It is possible to recover both the low-rank and\nthe sparse components exactly by solving a very convenient\nconvex program called Principal Component Pursuit; among all\nfeasible decompositions, simply minimize a weighted combination\nof the nuclear norm and of the L1 norm.
