Model selection criteria for a linear model to solve discrete ill-posed problems on the basis of singular decomposition and random projection

EG Revunova - Cybernetics and Systems Analysis, 2016 - Springer
Criteria are developed to determine the optimal number of components of a linear model in
solving a discrete ill-posed problem by the methods of truncated singular value …

Analytical study of error components for solving discrete ill-posed problems using random projections

EG Revunova - Cybernetics and Systems Analysis, 2015 - Springer
This article analytically studies the dependence of components of the error of reconstructing
the true signal on the number of rows of a random projection matrix. It is shown that, with …
