Computing f‐divergences and distances of high‐dimensional probability density functions

Numerical Linear Algebra with Applications, Volume 30, Issue 3, May 2023., 2023
Abstract Very often, in the course of uncertainty quantification tasks or data analysis, one has to deal with high‐dimensional random variables. Here the interest is mainly to compute characterizations like the entropy, the Kullback–Leibler divergence, more general f$$ f $$‐divergences, or other such characteristics based on the probability density ...

Overall dynamic body acceleration measures activity differently on large versus small aquatic animals

Methods in Ecology and Evolution, Volume 13, Issue 2, Page 447-458, February 2022., 2022
Abstract Acceleration‐based proxies for activity and energy expenditure are widely used in bio‐logging studies of animal movement and locomotion to explore biomechanical strategies, energetic costs of behaviour, habitat use and the impact of anthropogenic disturbance.

Parameter Estimation for Dynamical Systems Using a Deep Neural Network

Applied Computational Intelligence and Soft Computing, Volume 2022, Issue 1, 2022., 2022
The deep neural network (DNN) was applied for estimating a set of unknown parameters of a dynamical system whose measured data are given for a set of discrete time points. We developed a new vectorized algorithm that takes the number of unknowns (state variables) and number of parameters into consideration.

A counterfactual approach to measure the impact of wet grassland conservation on U.K. breeding bird populations

Conservation Biology, Volume 35, Issue 5, Page 1575-1585, October 2021., 2021
Abstract Wet grassland populations of wading birds in the United Kingdom have declined severely since 1990. To help mitigate these declines, the Royal Society for the Protection of Birds has restored and managed lowland wet grassland nature reserves to benefit these and other species.

Value of cervical electrical impedance spectroscopy to predict spontaneous preterm delivery in asymptomatic women: the ECCLIPPx prospective cohort study

Ultrasound in Obstetrics &Gynecology, Volume 58, Issue 2, Page 293-302, August 2021., 2021
ABSTRACT Objectives Preterm birth (PTB) accounts for two‐thirds of deaths of structurally normal babies and is associated with substantial lifetime healthcare costs. Prevention of PTB remains limited by the modest accuracy of prediction methods, namely transvaginal ultrasound (TVS) cervical length (CL) measurement and quantitative cervicovaginal fetal ...

Uso de evolución diferencial para la búsqueda de semillas en el método de Newton

Informes Científicos y Técnicos (Universidad Nacional de la Patagonia Austral), 2014
Una adecuada performance del método de Newton requiere una eficiente elección de la semilla, fundamentalmente en los casos en que la convergencia para la obtención de raéces sea altamente sensible a este punto inicial.
