Incoherence-optimal matrix completion
WebApr 1, 2024 · In contrast, there doesn't seem to be such an intuition for strong incoherence. The author showed that strong incoherence is actually not required for matrix completion, which is desirable since the strong incoherence was usually the dominant factor ( μ 1 ≥ μ 0) in previous bounds. WebIn [7], it was proved 1) that matrix completion is not as ill-posed as previously thought and 2) that exact matrix completion is possible by convex programming. The authors of [7] …

At present, the state-of-the-art reconstruction methods are based on the idea of low-rank Hankel matrix completion and solved by different singular value thresholding methods.

We show that it is not necessary to assume \emph{joint incoherence}, which is a standard but unintuitive and restrictive condition that is imposed by previous studies. This leads to a sample …

Furthermore, we will assume that Assumption 1 always holds, and that the rank k, the condition number ˙ 1 =˙ k, and the incoherence parameter 0 of the matrix Mare bounded from above by a constant, as n!1.

Matrix completion is not a good reference; it's a different problem. 8. The synthetic data in the experiments are not interesting. Sampling from normal distribution ensures incoherence.
