We propose a novel “low-rank + dual” model for the matrix decomposition problems. Based on the unitarily invariant property of the Schatten p-norm, we prove that the solution of the proposed model can be obtained by an “l∞+l1” minimization problem, thus a simple and fast algorithm can be provided to solve our new model. Furthermore, we find that applying “l∞+l1” to any vector can achieve a shifty...
