Robust Principal Component Analysis? - Columbia University
www.columbia.eduRobust Principal Component Analysis? 11:3 polynomial-time algorithm with strong performance guarantees under broad condi-tions.3 The problem we study here can be considered an idealized version of Robust PCA, in which we aim to recover a low-rank matrix L 0 from highly corrupted measure- ments M = L 0 + S 0.Unlike the small noise term N 0 in classical PCA, the entries in S
