Optimal approximation of a large matrix by a sum of projected linear mappings on prescribed subspaces
Phil Howlett, Anatoli Torokhti
We propose and justify a matrix reduction method for calculating the optimal approximation of an observed matrix by a sum $\sum_{i=1}^p \sum_{j=1}^…

An optimal linear filter for estimation of random functions in Hilbert space
Phil Howlett, Anatoli Totokhti
Let ${\mbox{$\mbox{\boldmath }$}}$ be a square-integrable, zero-mean, random vector with observable realizations in a Hilbert space , and let ${\mbox{$\mbox{\boldmath }$}}…

Combined Reduced-Rank Transform
Anatoli Torokhti, Phil Howlett
We propose and justify a new approach to constructing optimal nonlinear transforms of random vectors. We show that the proposed transform improves such characteristics of rank-redu…
