Block sparse representations of tensors using Kronecker Bases
(IEEE Signal Processing Society, 2013)
In this paper, we consider sparse representations of multidimensional signals (tensors) by generalizing the one-dimensional case (vectors). A new greedy algorithm, namely the Tensor-OMP algorithm, is proposed to compute a ...
Solving analytical structured formalisms in parallel using slice algorithm
(Universidad de Los Andes, 2009)
Teoremas de Murnaghan y Littlewood sobre productos de Kronecker de funciones simétricas
(Universidad Michoacana de San Nicolás de Hidalgo, 2021-09)
The Kronecker product of two homogeneous symmetric functions f and g, both of degree n, is defined by f * g = ch(ϕ▪ψ), where ch is the characteristic map of Frobenius and ϕ,ψ are complex characters of the symmetric group ...
Computing sparse representations of multidimensional signals using Kronecker bases
(M I T Press, 2013-01)
Recently, there is a great interest in sparse representations of signals under the assumption that signals (datasets) can be well approximated by a linear combination of few elements of a known basis (dictionary). Many ...
Stable, robust and super fast reconstruction of tensors using multi-way projections
(Institute of Electrical and Electronics Engineers, 2015-01)
In the framework of multidimensional Compressed Sensing (CS), we introduce an analytical reconstruction formula that allows one to recover an Nth-order data tensor X from a reduced set of multi-way compressive measurements ...
Cell-based maximum entropy approximants for three-dimensional domains: Application in large strain elastodynamics using the meshless total Lagrangian explicit dynamics method
(John Wiley & Sons Ltd, 2019-09)
We present the cell-based maximum entropy (CME) approximants in E3 space by constructing the smooth approximation distance function to polyhedral surfaces. CME is a meshfree approximation method combining the properties ...
Entanglement distillation using Schur-Weyl decomposition for three qubits
(Maestría en Ciencias - FísicaFacultad de CienciasDepartamento de Física, 2016)
El propósito de este trabajo es examinar las razones asintóticas a las cuales se presenta distilación de enredamiento en sistemas de tres qubits. El enfoque que se seguirá para ver esta concentración está basado en la ...
