Low-Rank Matrix Completion using Nuclear Norm
5 Minimization of the nuclear norm is often used as a surrogate, convex relaxation, for finding 6 the minimum rank completion (recovery) of a partial matrix. The minimum nuclear norm 7 problem can be solved as a trace minimization semidefinite programming problem (SDP ). 8 The SDP and its dual are regular in the sense that they both satisfy strict feasibility. Interior 9 point algorithms are th...
متن کاملOnline Matrix Completion Through Nuclear Norm Regularisation
It is the main goal of this paper to propose a novel method to perform matrix completion on-line. Motivated by a wide variety of applications, ranging from the design of recommender systems to sensor network localization through seismic data reconstruction, we consider the matrix completion problem when entries of the matrix of interest are observed gradually. Precisely, we place ourselves in t...
متن کاملMatrix completion via max-norm constrained optimization
This paper studies matrix completion under a general sampling model using the max-norm as a convex relaxation for the rank of the matrix. The optimal rate of convergence is established for the Frobenius norm loss. It is shown that the max-norm constrained minimization method is rate-optimal and it yields a more stable approximate recovery guarantee, with respect to the sampling distributions, t...
متن کاملFactor Matrix Nuclear Norm Minimization for Low-Rank Tensor Completion
Most existing low-n-rank minimization algorithms for tensor completion suffer from high computational cost due to involving multiple singular value decompositions (SVDs) at each iteration. To address this issue, we propose a novel factor matrix rank minimization method for tensor completion problems. Based on the CANDECOMP/PARAFAC (CP) decomposition, we first formulate a factor matrix rank mini...
متن کاملAnalysis of Nuclear Norm Regularization for Full-rank Matrix Completion
In this paper, we provide a theoretical analysis of the nuclear-norm regularized least squares for full-rank matrix completion. Although similar formulations have been examined by previous studies, their results are unsatisfactory because only additive upper bounds are provided. Under the assumption that the top eigenspaces of the target matrix are incoherent, we derive a relative upper bound f...
