Fast Algorithm for Constrained Linear Inverse Problems
Mohammed Rayyan Sheriff, Floor Fenne Redel, Peyman Mohajerin Esfahani
We consider the constrained Linear Inverse Problem (LIP), where a certain atomic norm (like the norm) is minimized subject to a quadratic constraint. Typically, such cost…
Novel min-max reformulations of Linear Inverse Problems
Mohammed Rayyan Sheriff, Debasish Chatterjee
In this article, we dwell into the class of so-called ill-posed Linear Inverse Problems (LIP) which simply refers to the task of recovering the entire signal from its relatively fe…
A complete characterization of optimal dictionaries for least squares representation
Mohammed Rayyan Sheriff, Debasish Chatterjee
Dictionaries are collections of vectors used for representations of elements in Euclidean spaces. While recent research on optimal dictionaries is focussed on providing sparse (i.e…
On a frame theoretic measure of quality of LTI systems
Mohammed Rayyan Sheriff, Debasish Chatterjee
It is of practical significance to define the notion of a measure of quality of a control system, i.e., a quantitative extension of the classical notion of controllability. In this…
