A Higher-Rank Mersenne Problem [PDF]

open access: yes, 2002
The classical Mersenne problem has been a stimulating challenge to number theorists and computer scientists for many years. After briefly reviewing some of the natural settings in which this problem appears as a special case, we introduce an analogue of the Mersenne problem in higher rank, in both a classical and an elliptic setting.

Reducing the rank of a matroid [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2015
We consider the rank reduction problem for matroids: Given a matroid $M$ and an integer $k$, find a minimum size subset of elements of $M$ whose removal reduces the rank of $M$ by at least $k$. When $M$ is a graphical matroid this problem is the minimum $

Rank revealing‐based tensor completion using improved generalized tensor multi‐rank minimization

open access: yesIET Signal Processing, 2021
The authors address the problem of tensor completion from limited samplings. An improved generalized tubal Kronecker decomposition is first proposed to reveal the tensor structure of the targeted data, and the improved generalized tensor tubal‐rank and ...

Multiple-rank modification of symmetric eigenvalue problem

open access: yesMethodsX, 2018
Rank-1 modifications applied k-times (k > 1) often are performed to achieve a rank-k modification. We propose a rank- k modification for enhancing computational efficiency. As the first step toward a rank- k modification, an algorithm to perform a rank-2

Approximate Message Passing for Structured Affine Rank Minimization Problem

open access: yesIEEE Access, 2017
The topic of the rank minimization problem with affine constraints has been well studied in recent years. However, in many applications the data can exhibit other structures beyond simply being low rank.

M-ary Rank Classifier Combination: A Binary Linear Programming Problem

open access: yesEntropy, 2019
The goal of classifier combination can be briefly stated as combining the decisions of individual classifiers to obtain a better classifier. In this paper, we propose a method based on the combination of weak rank classifiers because rankings contain ...
