Mutual information and sensitivity analysis for feature selection in customer targeting: a comparative study
Nestor Barraza, Sergio Moro, Marcelo Ferreyra +1
Feature selection is a highly relevant task in a data-driven knowledge discovery project. Several techniques have been developed aiming at finding the features that influence most…
A non-homogeneous Markov early epidemic growth dynamics model. Application to the SARS-CoV-2 pandemic
Nestor R. Barraza, Gabriel Pena, Verónica Moreno
This work introduces a new markovian stochastic model that can be described as a non-homogeneous Pure Birth process. We propose a functional form of birth rate that depends on the…
A non-homogeneous, non-stationary and path-dependent Markov anomalous diffusion model
Nestor Barraza, Gabriel Pena, Juliana Gambini +1
A novel probabilistic framework for modelling anomalous diffusion is presented. The resulting process is Markovian, non-homogeneous, non-stationary, non-ergodic, and state-dependen…
When researchers pay to publish: Results from a survey on APCs in four countries
Osvaldo Gallardo, Matías Milia, André Luiz Appel +2
This paper provides an empirical overview of the impact and practices of paying Article Processing Charges (APCs) by four nationally categorized groups of researchers in Argentina,…
Modeling the Mg I from the NUV to MIR. II. Testing stellar models
J. I. Peralta, M. C. Vieytes, A. M. P. Mendez +1
Aims. We tested the new atomic model using atmospheric models of stars of different spectral types: the Sun (dG2), HD22049 (dK2, Epsilon Eridani), GJ 832 (dM2), and GJ 581 (dM3). M…
Enthalpy-based modeling of tomographically reconstructed quiet-Sun coronal loops
C. Mac Cormack, M. López Fuentes, C. H. Mandrini +2
The structure of the solar corona is made of magnetic flux tubes or loops. Due to the lack of contrast with their environment, observing and studying coronal loops in the quiet Sun…
