Natural Interaction between Avatars and Persons with Alzheimer's Disease
Eduardo Carrasco,Gorka Epelde,Aitor Moreno,Amalia Ortiz,Igor García,Cristina Buiza,Elena Urdaneta,Aitziber Etxaniz,M. F. Gonzalez,Andoni Arruti +9 more
TL;DR: A natural human computer interaction paradigm is proposed for persons with cognitive impairments such as Alzheimer's Disease that uses a realistic virtual character, rendered on a common television set, to play the role of a virtual personal assistant that shows reminders, notifications and performs short dialogues with the user.
Journal ArticleDOI
Classifier Subset Selection to construct multi-classifiers by means of estimation of distribution algorithms
TL;DR: This work is based on the selection of the appropriate single classifiers by means of an evolutionary algorithm, and different base classifiers, which have been chosen from different classifier families, are used as candidates in order to obtain variability in the classifications given.
Journal ArticleDOI
A real-time stress classification system based on arousal analysis of the nervous system by an F-state machine.
TL;DR: A biophysical real-time stress identification and classification system, analysing two noninvasive signals, the galvanic skin response and the heart rate variability, is developed, able to detect and classify different stress stages only based on two non invasive signals.
Journal ArticleDOI
Classifier Subset Selection for the Stacked Generalization Method Applied to Emotion Recognition in Speech.
TL;DR: A new supervised classification paradigm, called classifier subset selection for stacked generalization (CSS stacking), is presented to deal with speech emotion recognition by means of an integration of an estimation of distribution algorithm (EDA) in the first layer to select the optimal subset from the standard base classifiers.
Journal Article
Feature subset selection based on evolutionary algorithms for automatic emotion recognition in spoken spanish and standard basque language
Aitor Álvarez,Idoia Cearreta,Juan Miguel López,Andoni Arruti,Elena Lazkano,Basilio Sierra,Nestor Garay +6 more
TL;DR: A study performed to analyze different Machine Learning techniques validity in automatic speech emotion recognition area using a bilingual affective database and techniques based on evolutive algorithms to select speech feature subsets that optimize automatic emotion recognition success rate.
