Restricted Isometry Property of Principal Component Pursuit with Reduced Linear Measurements
نویسندگان
چکیده
The principal component prsuit with reduced linear measurements (PCP RLM) has gained great attention in applications, such as machine learning, video, and aligningmultiple images.The recent research shows that strongly convex optimization for compressive principal component pursuit can guarantee the exact low-rank matrix recovery and sparse matrix recovery as well. In this paper, we prove that the operator of PCP RLM satisfies restricted isometry property (RIP) with high probability. In addition, we derive the bound of parameters depending only on observed quantities based on RIP property, which will guide us how to choose suitable parameters in strongly convex programming.

Sparse Recovery Algorithms: Sufficient Conditions in terms of Restricted Isometry Constants
We review three recovery algorithms used in Compressive Sensing for the reconstruction s-sparse vectors x ∈ CN from the mere knowledge of linear measurements y = Ax ∈ Cm, m < N. For each of the algorithms, we derive improved conditions on the restricted isometry constants of the measurement matrix A that guarantee the success of the reconstruction. These conditions are δ2s < 0.4652 for basis pu...
متن کاملOn the gap between restricted isometry properties and sparse recovery conditions
We consider the problem of recovering sparse vectors from underdetermined linear measurements via `pconstrained basis pursuit. Previous analyses of this problem based on generalized restricted isometry properties have suggested that two phenomena occur if p 6= 2. First, one may need substantially more than s log(en/s) measurements (optimal for p = 2) for uniform recovery of all s-sparse vectors...
متن کاملDeterministic Compressed Sensing Matrices from Additive Character Sequences
Compressed sensing is a novel technique where one can recover sparse signals from the undersampled measurements. In this correspondence, a K×N measurement matrix for compressed sensing is deterministically constructed via additive character sequences. The Weil bound is then used to show that the matrix has asymptotically optimal coherence for N = K, and to present a sufficient condition on the ...
