Randomized linear algebra for model reduction. Part I: Galerkin methods and error estimation [PDF]

open access: greenAdvances in Computational Mathematics, 2019
We propose a probabilistic way for reducing the cost of classical projection-based model order reduction methods for parameter-dependent linear equations. A reduced order model is here approximated from its random sketch, which is a set of low-dimensional random projections of the reduced approximation space and the spaces of associated residuals. This

Speeding up Linear Programming using Randomized Linear Algebra

open access: yes, 2020
Linear programming (LP) is an extremely useful tool and has been successfully applied to solve various problems in a wide range of areas, including operations research, engineering, economics, or even more abstract mathematical areas such as combinatorics.

Polynomial-Time Algorithms for Quadratic Isomorphism of Polynomials: The Regular Case [PDF]

open access: yes, 2015
Let $\mathbf{f}=(f\_1,\ldots,f\_m)$ and $\mathbf{g}=(g\_1,\ldots,g\_m)$ be two sets of $m\geq 1$ nonlinear polynomials over $\mathbb{K}[x\_1,\ldots,x\_n]$ ($\mathbb{K}$ being a field).

Randomized methods to characterize large-scale vortical flow networks.

open access: yesPLoS ONE, 2019
We demonstrate the effective use of randomized methods for linear algebra to perform network-based analysis of complex vortical flows. Network theoretic approaches can reveal the connectivity structures among a set of vortical elements and analyze their ...

Polynomial time algorithms for multicast network code construction [PDF]

open access: yes, 2005
The famous max-flow min-cut theorem states that a source node s can send information through a network (V, E) to a sink node t at a rate determined by the min-cut separating s and t.

Optimal CUR Matrix Decompositions [PDF]

open access: yes, 2014
The CUR decomposition of an $m \times n$ matrix $A$ finds an $m \times c$ matrix $C$ with a subset of $c < n$ columns of $A,$ together with an $r \times n$ matrix $R$ with a subset of $r < m$ rows of $A,$ as well as a $c \times r$ low-rank matrix $U ...

Efficient Black-Box Identity Testing for Free Group Algebras [PDF]

open access: yes, 2019
Hrubes and Wigderson [Pavel Hrubes and Avi Wigderson, 2014] initiated the study of noncommutative arithmetic circuits with division computing a noncommutative rational function in the free skew field, and raised the question of rational identity testing.

State Determination and Sufficiency of Observables [PDF]

open access: yes, 2013
Informational completeness and the possibility of state distinction and determination are among the more important issues of quantum statistics. We use spectral and semispectral (POV) measures to analyse these questions.
