When Data do not Bring Information: A Case Study in Markov Random Fields Estimation
J. Gimenez, A. C. Frery, Ana Georgina Flesia
The Potts model is frequently used to describe the behavior of image classes, since it allows to incorporate contextual information linking neighboring pixels in a simple way. Its…
Assessment of long-range correlation in animal behaviour time series: the temporal pattern of locomotor activity of Japanese quail (Coturnix coturnix) and mosquito larva (Culex quinquefasciatus)
Jackelyn M. Kembro, Ana Georgina Flesia, Raquel M. Gleiser +2
The aim of this study was to evaluate the performance of a classical method of fractal analysis, Detrended Fluctuation Analysis (DFA), in the analysis of the dynamics of animal beh…
Large gaps imputation in remote sensed imagery of the environment
Valeria Rulloni, Oscar Bustos, Ana Georgina Flesia
Imputation of missing data in large regions of satellite imagery is necessary when the acquired image has been damaged by shadows due to clouds, or information gaps produced by sen…
Pattern recognition on random trees associated to protein functionality families
A. G. Flesia, R. Fraiman, F. G. Leonardi
In this paper, we address the problem of identifying protein functionality using the information contained in its aminoacid sequence. We propose a method to define sequence similar…
