  • Alzheimer disease diagnosis based on automatic spontaneous speech analysis
    Lopez-de-Ipiña, Karmele; Alonso, Jesús B.; Solé-Casals, Jordi; Barroso, Nora; Faundez-Zanuy, Marcos; Ecay-Torres, Miriam; Travieso, Carlos M.; Ezeiza, Aitzol; Estanga, A. (SciTePress - Science and Technology Publications, 2012)
    Alzheimer’s disease (AD) is the most prevalent form of progressive degenerative dementia and it has a high socio-economic impact in Western countries, therefore is one of the most active research areas today. Its diagnosis ...
  • Alzheimer Disease Diagnosis based on Automatic Spontaneous Speech Analysis
    Lopez-de-Ipiña, Karmele; Alonso, Jesús B.; Solé-Casals, Jordi; Barroso, Nora; Faundez-Zanuy, Marcos; Ecay-Torres, Miriam; Travieso, Carlos M.; Ezeiza, Aitzol; Estanga, A. (2013)
    Alzheimer’s disease (AD) is the most prevalent form of progressive degenerative dementia and it has a high socio-economic impact in Western countries, therefore is one of the most active research areas today. Its diagnosis ...
  • Application of the Mutual Information Minimization to speaker recognition / identification improvement
    Solé-Casals, Jordi; Faundez-Zanuy, Marcos (Elsevier, 2006)
    In this paper we propose the inversion of nonlinear distortions in order to improve the recognition rates of a speaker recognizer system. We study the effect of saturations on the test signals, trying to take into account ...
  • Feature selection for automatic analysis of emotional response based on nonlinear speech modeling suitable for diagnosis of Alzheimer׳s disease
    Lopez-de-Ipiña, Karmele; Alonso, Jesús B.; Travieso, Carlos M.; Solé-Casals, Jordi; Ezeiza, Aitzol; Faundez-Zanuy, Marcos; Beitia, Blanca; Calvo, Pilar (Elsevier, 2015)
    Alzheimer׳s disease (AD) is the most common type of dementia among the elderly. This work is part of a larger study that aims to identify novel technologies and biomarkers or features for the early detection of AD and its ...
  • Maximum likelihood Linear Programming Data Fusion for Speaker Recognition
    Monte-Moreno, Enric; Chetouani, Mohamed; Faundez-Zanuy, Marcos; Solé-Casals, Jordi (Elsevier, 2009)
    Biometric system performance can be improved by means of data fusion. Several kinds of information can be fused in order to obtain a more accurate classification (identification or verification) of an input sample. In ...
  • New Approaches for Alzheimer’s Disease Diagnosis Based on Automatic Spontaneous Speech Analysis and Emotional Temperature
    Lopez-de-Ipiña, Karmele; Alonso, Jesús B.; Barroso, Nora; Faundez-Zanuy, Marcos; Ecay-Torres, Miriam; Solé-Casals, Jordi; Travieso, Carlos M.; Estanga, A.; Ezeiza, Aitzol (Springer, 2012)
    Alzheimer Disease (AD) is one of the most common dementia and their socio-economic relevance is growing. Its diagnosis is sometimes made by excluding other dementias, but definitive confirmation must await the ...
  • On Automatic Diagnosis of Alzheimer's Disease based on Spontaneous Speech Analysis and Emotional Temperature
    Lopez-de-Ipiña, Karmele; Alonso, Jesús B.; Solé-Casals, Jordi; Barroso, Nora; Henriquez, P.; Faundez-Zanuy, Marcos; Travieso, Carlos M.; Ecay-Torres, Miriam; Martinez-Lage, Pablo; Egiraun, Harkaitz (Springer, 2013)
    Alzheimer's disease is the most prevalent form of progressive degenerative dementia; it has a high socio-economic impact in Western countries. Therefore it is one of the most active research areas today. Alzheimer's is ...
  • On the Selection of Non-Invasive Methods Based on Speech Analysis Oriented to Automatic Alzheimer Disease Diagnosis
    Lopez-de-Ipiña, Karmele; Alonso, Jesús B.; Travieso, Carlos M.; Solé-Casals, Jordi; Egiraun, Harkaitz; Faundez-Zanuy, Marcos; Ezeiza, Aitzol; Barroso, Nora; Ecay-Torres, Miriam; Martinez-Lage, Pablo; Martinez de Lizardui, Unai (MDPI, 2013)
    The work presented here is part of a larger study to identify novel technologies and biomarkers for early Alzheimer disease (AD) detection and it focuses on evaluating the suitability of a new approach for early AD ...
  • Online drawings for dementia diagnose: in-air and pressure information analysis
    Faundez-Zanuy, Marcos; Sesa Nogueras, Enric; Roure Alcobé, Josep; Garré Olmo, Josep; Lopez-de-Ipiña, Karmele; Solé-Casals, Jordi (Springer, 2014)
    In this paper we present experimental results comparing on-line drawings for control population (left and right hand) as well as Alzheimer disease patients. The drawings have been acquired by means of a digitizing tablet, ...
  • Selection of Entropy Based Features for Automatic Analysis of Essential Tremor
    Lopez-de-Ipiña, Karmele; Solé-Casals, Jordi; Faundez-Zanuy, Marcos; Calvo, Pilar; Sesa Nogueras, Enric; Martinez de Lizardui, Unai; De La Riva, Patricia; Marti-Masso, Jose F.; Beitia, Blanca; Bergareche, Alberto (MDPI, 2016)
    Biomedical systems produce biosignals that arise from interaction mechanisms. In a general form, those mechanisms occur across multiple scales, both spatial and temporal, and contain linear and non-linear information. ...
  • Speaker recognition improvement using blind inversion of distortions
    Faundez-Zanuy, Marcos; Solé-Casals, Jordi (2004)
    In this paper we propose the inversion of nonlinear distortions in order to improve the recognition rates of a speaker recognizer system. We study the effect of saturations on the test signals, trying to take into ...
