Low-rank and sparse structures have been pro-foundly studied in matrix completion and com-pressed sensing. In this paper, we develop “Go Decomposition ” (GoDec) to efficiently and ro-bustly estimate the low-rank partL and the sparse part S of a matrix X = L + S + G with noise G. GoDec alternatively assigns the low-rank ap-proximation of X − S to L and the sparse ap-proximation of X − L to S. The algorithm can be significantly accelerated by bilateral random projections (BRP). We also propose GoDec for matrix completion as an important variant. We prove that the objective value ∥X − L − S∥2F converges to a local minimum, whileL and S lin-early converge to local optimums. Theoretically, we analyze the influence of L, S and G to the asymptotic...
