Indoor Crowd 3D Localization in Big Buildings from Wi-Fi Access Anonymous Data
(MDPI, 2019-09-27)
Indoor crowd localization and counting in big public buildings pose problems of infrastructure deployment, signal processing, and privacy. Conventional approaches based on optical cameras, either in the visible or infrared ...
Impact of Machine Learning Pipeline Choices in Autism Prediction from Functional Connectivity Data
(World Scientific, 2021-01-20)
Autism Spectrum Disorder (ASD) is a largely prevalent neurodevelopmental condition with a big social and economical impact affecting the entire life of families. There is an intense search for biomarkers that can be assessed ...
COLAEVA: Visual Analytics and Data Mining Web-Based Tool for Virtual Coaching of Older Adult Populations
(MDPI, 2021-10-30)
The global population is aging in an unprecedented manner and the challenges for improving the lives of older adults are currently both a strong priority in the political and healthcare arena. In this sense, preventive ...
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 ...
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 ...
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 ...
Actor-critic continuous state reinforcement learning for wind-turbine control robust optimization
(Elsevier, 2022-04)
[EN] The control of Variable-Speed Wind-Turbines (VSWT) extracting electrical power from the wind kinetic energy are composed of subsystems that need to be controlled jointly, namely the blade pitch and the generator torque ...
Clustering Cities over Features Extracted from Multiple Virtual Sensors Measuring Micro-Level Activity Patterns Allows One to Discriminate Large-Scale City Characteristics
(MDPI, 2023-05-29)
The impact of micro-level people’s activities on urban macro-level indicators is a complex question that has been the subject of much interest among researchers and policymakers. Transportation preferences, consumption ...
Automatic feedback and assessment of team-coding assignments in a DevOps context
(Springer, 2023)
We describe an automated assessment process for team-coding assignments based on DevOps best practices. This system and methodology includes the definition of Team Performance Metrics measuring properties of the software ...
