STRUCTURED MATRIX APPROXIMATIONS VIA TENSOR DECOMPOSITIONS

SIAM JOURNAL ON MATRIX ANALYSIS AND APPLICATIONS, 43(4), 1599–1626.

By: M. Kilmer* & A. Saibaba n

author keywords: structured matrices; tensor decompositions; Kronecker products; system identifica-tion; image deblurring; covariance matrices
TL;DR: The approach has three steps: map the structured matrix to tensors, use tensor compression algorithms, and map the compressed tensors back to obtain two different matrix representations -- sum of Kronecker products and block low-rank format. (via Semantic Scholar)

SIGNAL RECOVERY FROM INCONSISTENT NONLINEAR OBSERVATIONS

2022 IEEE INTERNATIONAL CONFERENCE ON ACOUSTICS, SPEECH AND SIGNAL PROCESSING (ICASSP), pp. 5872–5876.

By: P. Combettes n & Z. Woodstock n

author keywords: Firmly nonexpansive operator; inconsistent nonlinear observations; signal recovery; variational inequality
TL;DR: To address problems with inaccurate measurements, this work proposes solving a variational inequality relaxation which is guaranteed to possess solutions under mild conditions and which coincides with the original problem if it happens to be consistent. (via Semantic Scholar)

BLOCK-ACTIVATED ALGORITHMS FOR MULTICOMPONENT FULLY NONSMOOTH MINIMIZATION

2022 IEEE INTERNATIONAL CONFERENCE ON ACOUSTICS, SPEECH AND SIGNAL PROCESSING (ICASSP), pp. 5428–5432.

By: M. Bui n, P. Combettes n & Z. Woodstock n

author keywords: Block-activated algorithm; image recovery; machine learning; nonsmooth convex minimization; proximal splitting
TL;DR: This work investigates the application of block-activated proximal algorithms for solving multicomponent minimization problems involving a separable nonsmooth convex function penalizing the components individually, and nonsm Smooth convex coupling terms penalizing linear mixtures of the components.
