  • Algoritmos interactivos para la separación de fuentes y deconvolución de canal mediante Java
    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 ...
  • Blind Inversion of Wiener System using a minimization-projection (MP) approach
    Babaie-Zadeh, Massoud; Solé-Casals, Jordi; Jutten, Christian (2003)
    In this paper, a new algorithm for blind inversion of Wiener systems is presented. The algorithm is based on minimization of mutual information of the output samples. This minimization is done through a Minimization-Projection ...
  • Blind Inversion of Wiener Systems
    Taleb, Anisse; Solé-Casals, Jordi; Jutten, Christian (Springer, 1999)
    A system in which a linear dynamic part is followed by a non linear memoryless distortion a Wiener system is blindly inverted This kind of systems can be modelised as a postnonlinear mixture and using some results ...
  • Estimación de funciones no lineales en mezclas post-no lineales
    Solé-Casals, Jordi; Jutten, Christian (2007)
    This paper proposes a new method for blindly inverting a nonlinear mapping which transforms a sum of random variables. This is the case of post-nonlinear (PNL) source separation mixtures. The importance of the method is ...
  • A Gradient based algorithm for blind inversion of Wiener System using multi-variate score functions
    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 ...
  • Improving algorithm speed in PNL mixture separation and Wiener system inversion
    Solé-Casals, Jordi; Babaie-Zadeh, Massoud; Jutten, Christian; Pham, Dinh-Tuan (2003)
    This paper proposes a very simple method for increasing the algorithm speed for separating sources from PNL mixtures or invertingWiener systems. The method is based on a pertinent initialization of the inverse system, ...
  • Initialisation of Nonlinearities for PNL and Wiener systems Inversion
    Solé-Casals, Jordi; Jutten, Christian; Pham, Dinh-Tuan (Springer, 2003)
    This paper proposes a very fast method for blindly initial- izing a nonlinear mapping which transforms a sum of random variables. The method provides a surprisingly good approximation even when the basic assumption is ...
  • Post-Nonlinear Mixtures and Beyond
    Solé-Casals, Jordi; Jutten, Christian (TSI Press, 2004)
    Although sources in general nonlinear mixturm arc not separable iising only statistical independence, a special and realistic case of nonlinear mixtnres, the post nonlinear (PNL) mixture is separable choosing a suited ...
  • Source separation techniques applied to linear prediction
    Solé-Casals, Jordi; Jutten, Christian; Taleb, Anisse (2000)
    The prediction filters are well known models for signal estimation, in communications, control and many others areas. The classical method for deriving linear prediction coding (LPC) filters is often based on the minimization ...
  • Web didáctica para la aproximación de funciones mediante redes neuronales
    Comabella López, Julio; Solé-Casals, Jordi; Hosseini, Sharam; Jutten, Christian (2002)
    In this article we presents a project [1] developed to demonstrate the capability that Multi-Layer Perceptrons (MLP) have to approximate non-linear functions [2]. The simulation has been implemented in Java to be used ...
