Efficient implementation of symplectic implicit Runge-Kutta schemes with simplified Newton iterations
(2017-03-30)
We are concerned with the efficient implementation of symplectic
implicit Runge-Kutta (IRK) methods applied to systems of (non-necessarily
Hamiltonian) ordinary differential equations by means of Newton-like iterations. ...
Reducing and monitoring round-off error propagation for symplectic implicit Runge-Kutta schemes
(2017-01-31)
We propose an implementation of symplectic implicit Runge-Kutta schemes for highly accurate numerical integration of non-stiff Hamiltonian systems based on fixed point iteration. Provided that the computations are done in ...
Behavioral Activity Recognition Based on Gaze Ethograms
(World Scientific Publishing, 2020-07)
Noninvasive behavior observation techniques allow more natural human behavior assessment experiments with higher ecological validity. We propose the use of gaze ethograms in the context of user interaction with a computer ...
Deep transfer learning-based gaze tracking for behavioral activity recognition
(Elsevier, 2022-08)
Computational Ethology studies focused on human beings is usually referred as Human Activity Recognition (HAR). Specifically, this paper belongs to a line of work on the identification of broad cognitive activities that ...
Identification of a biomarker panel for colorectal cancer diagnosis
(BioMed Central, 2012-01-26)
Background: Malignancies arising in the large bowel cause the second largest number of deaths from cancer in the Western World. Despite progresses made during the last decades, colorectal cancer remains one of the most ...
Combining Geostatistics and Remote Sensing Data to Improve Spatiotemporal Analysis of Precipitation
(MDPI, 2021-04-30)
The wide availability of satellite data from many distributors in different domains of science has provided the opportunity for the development of new and improved methodologies to aid the analysis of environmental problems ...
Triku: a feature selection method based on nearest neighbors for single-cell data
(Oxford University Press, 2022-03-12)
Abstract
BACKGROUND: Feature selection is a relevant step in the analysis of single-cell RNA sequencing datasets. Most of the current feature selection methods are based on general univariate descriptors of the data ...
Survival of Frail Elderly with Delirium
(MDPI, 2022-02-16)
This study aims to determine when frailty increases the risks of delirium mortality. Hospital patients falling into the elderly frail or pre-frail category were recruited, some without delirium, some with delirium at ...
Community structure in real-world networks from a non-parametrical synchronization-based dynamical approach
(Elsevier, 2012-07-20)
[EN]This work analyzes the problem of community structure in real-world networks based on the synchronization of nonidentical coupled chaotic Rössler oscillators each one characterized by a defined natural frequency, and ...
Multi-View Graph Fusion for Semi-Supervised Learning: Application to Image-Based Face Beauty Prediction
(MDPI, 2022)
Facial Beauty Prediction (FBP) is an important visual recognition problem to evaluate the attractiveness of faces according to human perception. Most existing FBP methods are based on supervised solutions using geometric ...
