Efficient Algorithms for CUR and Interpolative Matrix Decompositions
Sergey Voronin, Per-Gunnar Martinsson
The manuscript describes efficient algorithms for the computation of the CUR and ID decompositions. The methods used are based on simple modifications to the classical truncated pi…
Convolution based smooth approximations to the absolute value function with application to non-smooth regularization
Sergey Voronin, Gorkem Ozkaya, Davis Yoshida
We present new convolution based smooth approximations to the absolute value function and apply them to construct gradient based algorithms such as the nonlinear conjugate gradient…
Compression Approaches for the Regularized Solutions of Linear Systems from Large-Scale Inverse Problems
Sergey Voronin, Dylan Mikesell, Guust Nolet
We introduce and compare new compression approaches to obtain regularized solutions of large linear systems which are commonly encountered in large scale inverse problems. We first…
