A non-extensive maximum entropy based regulations method for bad conditioned inverse problems
(1998-01)
Article
Accés obertA regularization method based on the non-extensive maximum entropy principle is devised. Special emphasis is given to the q=1/2 case. We show that, when the residual principle is considered as constraint, the q=1/2 generalized ... -
Frames: a maximum entropy statistical estimate of the inverse problem
(1997-01)
Article
Accés obertA maximum entropy statistical treatment of an inverse problem concerning frame theory is presented. The problem arises from the fact that a frame is an overcomplete set of vectors that defines a mapping with no unique ... -
Un método de máxima entropía para el análisis de una mezcla de tierras raras
(Centro Internacional de Métodos Numéricos en Ingeniería, 1994)
Article
Accés obertSe propone un método basado en el Principio de Máxima Entropía para analizar mezclas de Tierras Raras en base a medidas magnéticas. El algoritmo está especialmente diseñado para tener en cuenta el error de los datos y la ... -
On the inverse windowed Fourier transform
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1999-11-30)
Article
Accés obertThe inversion problem concerning the windowed Fourier transform is considered. It is shown that, out of the infinite solutions that the problem admits, the windowed Fourier transform is the "optimal" solution according to ... -
On the q=1/2 non-extensive maximum entropy distribution
(1998-01)
Article
Accés obertA detailed mathematical analysis on the q = 1/2 non-extensive maximum entropy distribution of Tsallis' is undertaken. The analysis is based upon the splitting of such a distribution into two orthogonal components. One ... -
On wideband deconvolution using wavelet transform
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1997-07-31)
Article
Accés obertA discussion on the expression proposed in [1]–[3] for deconvolving the wideband density function is presented. We prove here that such an expression reduces to be proportional to the wideband correlation receiver output, ... -
Reconstruction of the join time-delay Doppler-scale reflectivity density in the wide-band regime. A frame theory based approach
(American Institute of Physics, 2000-08-31)
Article
Accés restringit per política de l'editorialThe inverse scattering problem concerning the determination of the joint time-delay Doppler-scale reflectivity density characterizing continuous target environments is addressed by recourse to the generalized frame theory. ... -
The continuous wavelet transform as a maximum entropy solution of the corresponding inverse problem
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1999-07-31)
Article
Accés obertThe continuous wavelet transform is obtained as a maximum entropy solution of the corresponding inverse problem. It is well known that although a signal can be reconstructed from its wavelet transform, the expansion is ...
