Hankel matrix completion
Webthe originally ill-posed completion problem can find an acceptable solution by exploiting the knowledge of the associated displacement rank. In this work we address the specific MC problem for the recovery of a low-rank structured matrix with low L-displacement rank, which is a special case of the matrix completion problem (1.1). WebA fully data-driven deep learning algorithm for k-space interpolation based on convolutional neural networks to Hankel matrix decomposition using datadriven framelet basis is proposed. The annihilating filter-based low-rank Hankel matrix approach (ALOHA) is one of the state-of-the-art compressed sensing approaches that directly interpolates the missing …

We now turn to the regularized minimum rank Hankel completion problem (4) and the convex heuristic (5) for it, applied to a stochastic realization problem. Consider a state WebJan 1, 2015 · The previous sections study rank one Hankel matrix completion problem where the revealed entries follow a deterministic pattern. It is natural to raise the question whether the nuclear norm heuristic will still work when the rank of the Hankel matrix is greater than 1. This is not always the case.
