Nonlinear Distributionally Robust Optimization

Mohammed Rayyan Sheriff, Peyman Mohajerin Esfahani

This article focuses on a class of distributionally robust optimization (DRO) problems where, unlike the growing body of the literature, the objective function is potentially nonli…

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…

Dictionary Learning with Almost Sure Error Constraints

Mohammed Rayyan Sheriff, Debasish Chatterjee

A dictionary is a database of standard vectors, so that other vectors / signals are expressed as linear combinations of dictionary vectors, and the task of learning a dictionary fo…

On Convex Duality in 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) in machine learning, which has become almost a classic in recent times. The fundamental…

Measure of quality of finite-dimensional linear systems: A frame-theoretic view

Mishal Assif PK, Mohammed Rayyan Sheriff, Debasish Chatterjee

A measure of quality of a control system is a quantitative extension of the classical binary notion of controllability. In this article we study the quality of linear control syste…

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…

Optimal dictionary for least squares representation

Mohammed Rayyan Sheriff, Debasish Chatterjee

Dictionaries are collections of vectors used for representations of random vectors in Euclidean spaces. Recent research on optimal dictionaries is focused on constructing dictionar…
