  • Rojas, Fernando; Solé-Casals, Jordi; Monte-Moreno, Enric; Puntonet, Carlos G.; Prieto, Alberto (Springer, 2006)
    It is well known the relationship between source separation and blind deconvolution: If a filtered version of an unknown i.i.d. signal is observed, temporal independence between samples can be used to retrieve the original ...
  • Lew, Sergio; Solé-Casals, Jordi; Caiafa, Cesar F.; Bau i Macià, Josep (2012)
    In this work, we propose a copula-based method to generate synthetic gene expression data that account for marginal and joint probability distributions features captured from real data. Our method allows us to implant ...
  • Solé-Casals, Jordi; Caiafa, Cesar F. (Springer, 2013)
    When dealing with nonlinear blind processing algorithms (deconvolution or post-nonlinear source separation), complex mathematical estimations must be done giving as a result very slow algorithms. This is the case, for ...
  • Babaie-Zadeh, Massoud; Solé-Casals, Jordi; Jutten, Christian (2003)
    A Wiener system is a linear time-invariant filter, followed by an invertible nonlinear distortion. Assuming that the input signal is an independent and identically distributed (iid) sequence, we propose an algorithm ...
  • Al-Baddai, Saad; Al-Subari, Karema; Tomé, Ana Maria; Solé-Casals, Jordi; Lang, Elmar W. (Elsevier, 2016)
    Bidimensional Empirical Mode Decomposition (BEMD) interprets an image as a superposition of Bidimensional Intrinsic Mode Functions (BIMFs). They are extracted by a process called sifting, which encompasses two-dimensional ...
  • Gallego Jutglà, Esteve; Solé-Casals, Jordi; Vialatte, François B.; Elgendi, Mohamed; Cichocki, Andrej; Dauwels, Justin (IOS Press, 2015)
    Objective. Recently, significant advances have been made in the early diagnosis of Alzheimer’s disease from EEG. However, choosing suitable measures is a challenging task. Among other measures, frequency Relative Power and ...
  • Solé-Casals, Jordi; Zaiats, Vladimir (Springer, 2010)
    This paper deals with non-linear transformations for improving the performance of an entropy-based voice activity detector (VAD). The idea to use a non-linear transformation has already been applied in the field of ...
  • Solé-Casals, Jordi; Vancea, Mihaela; March Amengual, Jaume Miquel (2014)
    This article explores the potential of ICT-based biometrics for monitoring the health status of the elderly people. It departs from specific ageing and biometric traits to then focus on behavioural biometric traits like ...
  • Comas, C.; Monte-Moreno, Enric; Solé-Casals, Jordi (Springer, 2005)
    In this paper we propose an endpoint detection system based on the use of several features extracted from each speech frame, followed by a robust classifier (i.e Adaboost and Bagging of decision trees, and a multilayer ...
  • Solé-Casals, Jordi; Caiafa, Cesar F. (Springer, 2011)
    When dealing with nonlinear blind deconvolution, complex mathematical estimations must be done giving as a result very slow algorithms. This is the case, for example, in speech processing or in microarray data analysis. ...
  • Gallego Jutglà, Esteve; Solé-Casals, Jordi; Vialatte, François B.; Dauwels, Justin; Cichocki, Andrej (IOS Press, 2015)
    Despite recent advances, early diagnosis of Alzheimer’s disease (AD) from electroencephalography (EEG) remains a difficult task. In this paper, we offer an added measure through which such early diagnoses can potentially ...
  • Bartés i Serrallonga, Manel; Serra Grabulosa, Josep M.; Adan, Ana; Falcón, Carles; Bargalló, Núria; Solé-Casals, Jordi (SciTePress - Science and Technology Publications, 2012)
    One problem of fMRI images is that they include some noise coming from many other sources like the heart beat, breathing and head motion artifacts. All these sources degrade the data and can cause wrong results in the ...
  • Jiménez Reifs, David; Solé-Casals, Jordi; Jutten, Christian (2000)
    El objetivo de estos programas es crear una herramienta que nos permita, de una manera fácil, entender mejor la separación de fuentes y la deconvolución de canal . Por eso se presenta el diseño, mediante Java, de una ...
  • Solé-Casals, Jordi; Vialatte, François B.; Dauwels, Justin (Springer, 2015)
    Neural signal processing is a discipline within neuroengineering. This interdisciplinary approach combines principles from machine learning, signal processing theory, and computational neuroscience applied to problems in ...
  • 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 ...

  • Rojas, Fernando; Solé-Casals, Jordi; Puntonet, Carlos G. (2007)
    The problem of blind inversion of Wiener systems can be considered as a special case of blind separation of post-nonlinear instantaneous mixtures. In this paper, we present an approach for nonlinear deconvolution of one ...
  • 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 ...
  • Zaiats, Vladimir; Solé-Casals, Jordi; Martí i Puig, Pere; Reig Bolaño, Ramon (Springer, 2010)
    This paper analyzes applications of cumulant analysis in speech processing. The main focus is made on an integral representation for cUl1luJants using integrals involving cyclic products of kernels. These integrals serve ...
