Attraction-repulsion clustering: a way of promoting diversity linked to demographic parity in fair clustering
(2022-10-20)We consider the problem of diversity enhancing clustering, i.e, developing clustering methods which produce clusters that favour diversity with respect to a set of protected attributes such as race, sex, age, etc. In the ... -
Automated location of orofacial landmarks to characterize airway morphology in anaesthesia via deep convolutional neural networks
(2023-04)Background:A reliable anticipation of a difficult airway may notably enhance safety during anaesthesia. In current practice, clinicians use bedside screenings by manual measurements of patients’ morphology. Objective:To ... -
Extracting relevant predictive variables for COVID-19 severity prognosis: An exhaustive comparison of feature selection techniques
(2023)With the COVID-19 pandemic having caused unprecedented numbers of infections and deaths, large research efforts have been undertaken to increase our understanding of the disease and the factors which determine diverse ... -
Variable selection in high-dimensional data: application in a SARS-CoV-2 pneumonia clinical data-set
(2021-09-15)As a result of the COVID-19 pandemic that collapsed hospitals in some countries, numerous studies have been carried out to understand the development of the disease and how it affects patients with different characteristics, ... -
Development of machine learning system for airway prediction from facial image with mobile device
(2022-06)Goals: A reliable prognostic tool for a difficult airway (DA) may enhance patients’ safety during orotracheal intubation by decreasing unanticipated DAs. We aim to examine the applicability of an Artificial Intelligence-Deep ... -
Desarrollo de sistema de Machine Learning para la prediccion de vía aérea a partir de imagen facial con dispositivo movil
(2022-04)El manejo de una vía aérea difícil (VAD) representa aún una causa importante de lesiones relacionadas con la anestesia, cuyas complicaciones son potencialmente mortales. El notable interés en la predicción de VAD ha provocado ... -
Impacto cuantitativo de la contaminación en la probabilidad de muerte por neumonía por SARS-CoV-2
(2021-11)Introducción La evidencia científica disponible señala que la contaminación del aire exterior podría agravar la severidad de la COVID-19 y por ende, incrementar las probabilidades de fallecimiento. Material y métodos Estudio ... -
Predicción de la gravedad de neumonías por SARS-CoV-2 a partir de información clínica y contaminación, mediante inteligencia artificial
(2021-11)Introducción La contaminación del aire exterior se ha relacionado con mayor gravedad de las infecciones respiratorias. Por tanto, su inclusión en algoritmos predictivos podrían añadir información para pronosticar la ... -
A two-stage approach for the spatio-temporal analysis of high-throughput phenotyping data
(2022-02-24)High throughput phenotyping (HTP) platforms and devices are increasingly used for the characterization of growth and developmental processes for large sets of plant genotypes. Such HTP data require challenging statistical ... -
Modeling latent spatio-temporal disease incidence using penalized composite link models
(2022-03-10)Epidemiological data are frequently recorded at coarse spatio-temporal resolutions to protect confidential information or to summarize it in a compact manner. However, the detailed patterns followed by the source data, ... -
Prediction of sports injuries in football: a recurrent time-to-event approach using regularized Cox models
(2021-11-20)Data-based methods and statistical models are given special attention to the study of sports injuries to gain in-depth understanding of its risk factors and mechanisms. The objective of this work is to evaluate the use of ... -
A survey of bias in machine learning through the prism of statistical parity
(2020)Applications based on machine learning models have now become an indispensable part of the everyday life and the professional world. As a consequence, a critical question has recently arose among the population: Do algorithmic ... -
Package wsbackfit for Smooth Backfitting Estimation of Generalized Structured Models
(2021-01-01)A package is introduced that provides the weighted smooth backfitting estimator for a large family of popular semiparametric regression models. This family is known as generalized structured models, comprising, for example, ... -
ROCnReg: An R Package for Receiver Operating Characteristic Curve Inference With and Without Covariates
(2021-01-01)This paper introduces the package ROCnReg that allows estimating the pooled ROC curve, the covariate-specific ROC curve, and the covariate-adjusted ROC curve by different methods, both from (semi) parametric and nonparametric ... -
Phenomics data processing: A plot-level model for repeated measurements to extract the timing of key stages and quantities at defined time points
(2021)Decision-making in breeding increasingly depends on the ability to capture and predict crop responses to changing environmental factors. Advances in crop modeling as well as high-throughput eld phenotyping (HTFP) hold ... -
