Sampling Strategies for Uncertainty Reduction in Categorical Random Fields: Formulation, Mathematical Analysis and Application to Multiple-Point Simulations
(Springer Verlag, 2019)
© 2019, International Association for Mathematical Geosciences.The task of optimal sampling for the statistical simulation of a discrete random field is addressed from the perspective of minimizing the posterior uncertainty ...
Entropy Measures for Stochastic Processes with Applications in Functional Anomaly Detection
(Molecular Diversity Preservation International, 2018-01)
We propose a definition of entropy for stochastic processes. We provide a reproducing kernel Hilbert space model to estimate entropy from a random sample of realizations of a stochastic process, namely functional data, and ...
Multi-q pattern analysis: A case study in image classification
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
This paper compares the effectiveness of the Tsallis entropy over the classic Boltzmann-Gibbs-Shannon entropy for general pattern recognition, and proposes a multi-q approach to improve pattern analysis using entropy. A ...
Synthesis and crystal phase evaluation of hydroxylapatite using the rietveld-maximum entropy method
(2004-12-01)
Bioceramic systems based on hydroxylapatite (HAP) are an important class of bioactive materials that may promote bone regeneration. The aim of this research was to evaluate how the stoichiometry of HAP influences its ...

Periodicity and Texel Size Estimation of Visual Texture Using Entropy Cues
(Revista Computación y Sistemas; Vol. 14 No. 3, 2011-03-08)
Abstract. Texture periodicity and texture element (texel)
size are important characteristics for texture recognition
and discrimination. In this paper, an approach to
determine both, texture periodicity and texel size, ...
Complexity Analyses of Sao Francisco River Streamflow: Influence of Dams and Reservoirs
(American Society of Civil Engineers, 2020-10)
This study investigated the potential of methods from information science to detect hydrological alterations caused by human activity. In particular, the influence of the construction of a cascade of dams and reservoirs ...
