Exploiting the the nonzero diagonal pattern in matrix function computations
Majed Hamadi, Nezam Mahdavi-Amiri, Marcel Schweitzer
We consider the task of approximating a matrix function , where is a matrix in which only a relatively small number of (not necessarily consecutive) sub- and superdiagona…
Image Enhancement via Bilateral Learning
Saeedeh Rezaee, Nezam Mahdavi-Amiri
Nowadays, due to advanced digital imaging technologies and internet accessibility to the public, the number of generated digital images has increased dramatically. Thus, the need f…
Nonconvex weak sharp minima on Riemannian manifolds
M. Mahdi Karkhaneei, Nezam Mahdavi-Amiri
We are to establish necessary conditions (of the primal and dual types) for the set of weak sharp minima of a nonconvex optimization problem on a Riemannian manifold. Here, we are…
Computing Symmetric Positive Definite Solutions of Three Types of Nonlinear Matrix Equations
Negin Bagherpour, Nezam Mahdavi-Amiri
Nonlinear matrix equations arise in many practical contexts related to control theory, dynamical programming and finite element methods for solving some partial differential equati…
Efficient Algorithms for Positive Semi-Definite Total Least Squares Problems, Minimum Rank Problem and Correlation Matrix Computation
Negin Bagherpour, Nezam Mahdavi-Amiri
We have recently presented a method to solve an overdetermined linear system of equations with multiple right hand side vectors, where the unknown matrix is to be symmetric and pos…
A New Error in Variables Model for Solving Positive Definite Linear System Using Orthogonal Matrix Decompositions
Negin Bagherpour, Nezam Mahdavi Amiri
The need to estimate a positive definite solution to an overdetermined linear system of equations with multiple right hand side vectors arises in several process control contexts.…
