Empirical and Philosophical Problems with the Subspecies Rank

open access: yesEcology and Evolution, 2022
Species-level taxonomy is derived from methodological sources (data and techniques) that assess the existence of spatio-temporal evolutionary lineages via various species concepts. These concepts determine if observed lineages are independent given a particular methodology supposedly connected to ontology, which relates the metaphysical concept to what

Alternating Direction Method of Multipliers for Sparse and Low-Rank Decomposition Based on Nonconvex Nonsmooth Weighted Nuclear Norm

open access: yesIEEE Access, 2018
Sparse and low-rank decomposition (SLRD) poses a big challenge in many fields. The existing methods are used to solve SLRD problem via formulating approximations of sparse and low-rank matrices.

Quantum-Inspired Hierarchy for Rank-Constrained Optimization

open access: yesPRX Quantum, 2022
Many problems in information theory can be reduced to optimizations over matrices, where the rank of the matrices is constrained. We establish a link between rank-constrained optimization and the theory of quantum entanglement.

The augmented lagrange multipliers method for matrix completion from corrupted samplings with application to mixed Gaussian-impulse noise removal. [PDF]

open access: yesPLoS ONE, 2014
This paper studies the problem of the restoration of images corrupted by mixed Gaussian-impulse noise. In recent years, low-rank matrix reconstruction has become a research hotspot in many scientific and engineering domains such as machine learning ...

Low-rank sparse subspace clustering with a clean dictionary

open access: yesJournal of Algorithms & Computational Technology, 2021
Low-Rank Representation (LRR) and Sparse Subspace Clustering (SSC) are considered as the hot topics of subspace clustering algorithms. SSC induces the sparsity through minimizing the l 1 -norm of the data matrix while LRR promotes a low-rank structure ...

On the Complexity of the Rank Syndrome Decoding Problem [PDF]

open access: yesIEEE Transactions on Information Theory, 2016
In this paper we propose two new generic attacks on the Rank Syndrome Decoding (RSD) problem Let $C$ be a random $[n,k]$ rank code over $GF(q^m)$ and let $y=x+e$ be a received word such that $x \in C$ and the $Rank(e)=r$. The first attack is combinatorial and permits to recover an error $e$ of rank weight $r$ in $min(O((n-k)^3m^3q^{r\lfloor\frac{km}{n}\

An Adaptive Rank Aggregation-Based Ensemble Multi-Filter Feature Selection Method in Software Defect Prediction

open access: yesEntropy, 2021
Feature selection is known to be an applicable solution to address the problem of high dimensionality in software defect prediction (SDP). However, choosing an appropriate filter feature selection (FFS) method that will generate and guarantee optimal ...

A New Technique in Rank Metric Code-Based Encryption

open access: yesCryptography, 2018
We propose a rank metric codes based encryption based on the hard problem of rank syndrome decoding problem. We propose a new encryption with a public key matrix by considering the adding of a random distortion matrix over F q m of full column ...

Nonconvex Low Tubal Rank Tensor Minimization

open access: yesIEEE Access, 2019
In the sparse vector recovery problem, the L0-norm can be approximated by a convex function or a nonconvex function to achieve sparse solutions. In the low-rank matrix recovery problem, the nonconvex matrix rank can be replaced by a convex function or a ...
