  • Ponderación ML de parámetros en un sistema de reconocimiento de palabras basado en CDHMM 

    Valverde Amador, Antonio Javier; Hernando Pericás, Francisco Javier; Nogueiras Rodríguez, Albino (1996)
    Conference lecture
    Open Access
    Speech dynamic feature are routinely used in current speech recognition systems in combination with short-term (static) spectral features. The aim of this paper is to propose a method to automatically estimate the optimum ...
  • Modelado de la trayectoria de los polos en la secuencia de LPC 

    Freitag, Fèlix; Monte Moreno, Enrique; Hernando Pericás, Francisco Javier (Universidad de Valladolid, 1995)
    Conference report
    Open Access
    A alternative way of representing time variations of the speech spectra is presented. We propose to model the trajectories of the poles of the LPC analysis spectra using exponential functions as alternative to delta ...
  • On the use of the derivative of pole trajectories of the LPC analysis parameter sequence as an alternative to delta parameters 

    Freitag, Fèlix; Monte Moreno, Enrique; Hernando Pericás, Francisco Javier (1995)
    Conference report
    Open Access
    In this paper a new approach for modelling time variations in the speech spectra is presented. We propose to approximate the trajectories of the frequency and amplitude of the poles of the LPC spectra with exponential ...
  • Evaluating the impact of OpenMP 4.0 extensions on relevant parallel workloads 

    Vidal Ortiz, Raul; Casas Guix, Marc; Moreto Planas, Miquel; Chasapis, Dimitrios; Ferrer Ibáñez, Roger; Martorell Bofill, Xavier; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José; Valero Cortés, Mateo (Springer, 2015)

    OpenMP has been for many years the most widely used programming model for shared memory architectures. Periodically, new features are proposed and some of them are finally selected for inclusion in the OpenMP standard. The ...
  • Runtime-guided management of scratchpad memories in multicore architectures 

    Álvarez Martí, Lluc; Moreto Planas, Miquel; Casas Guix, Marc; Castillo Villar, Emilio; Martorell Bofill, Xavier; Labarta Mancho, Jesús José; Ayguadé Parra, Eduard; Valero Cortés, Mateo (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference report
    Open Access
    The increasing number of cores and the anticipated level of heterogeneity in upcoming multicore architectures cause important problems in traditional cache hierarchies. A good way to alleviate these problems is to add ...
  • Segmentación y formulación de realimentación en el análisis de la difracción de objetos grandes 

    Cruellas Ibarz, Juan Carlos; Ferrando Bataller, Miquel (1989)
    Conference report
    Open Access
    In this work, the application of the feedback formulation to study several objects that have been attached to form a bigger scatterer is presented. With this technique, a large obstacle can be segmented in several ones and ...
  • Predictive neural networks applied to phoneme recognition 

    Freitag, Fèlix; Monte Moreno, Enrique; Salavedra Molí, Josep (1997)
    Conference report
    Open Access
    In this paper a phoneme recognition system based on predictive neural networks is proposed. Neural networks are used to predict observation vectors of speech frames. The obtained prediction error is used for phoneme ...
  • Exploiting asynchrony from exact forward recovery for DUE in iterative solvers 

    Jaulmes, Luc; Casas Guix, Marc; Moreto Planas, Miquel; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José; Valero Cortés, Mateo (Association for Computing Machinery (ACM), 2015)
    Conference report
    Open Access
    This paper presents a method to protect iterative solvers from Detected and Uncorrected Errors (DUE) relying on error detection techniques already available in commodity hardware. Detection operates at the memory page ...
  • Runtime-aware architectures 

    Casas Guix, Marc; Moreto Planas, Miquel; Álvarez Martí, Lluc; Castillo Villar, Emilio; Chasapis, Dimitrios; Hayes, Timothy; Jaulmes, Luc; Palomar Pérez, Óscar; Unsal, Osman Sabri; Cristal Kestelman, Adrián; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José; Valero Cortés, Mateo (Springer, 2015)
    Conference report
    Open Access
    In the last few years, the traditional ways to keep the increase of hardware performance to the rate predicted by the Moore’s Law have vanished. When uni-cores were the norm, hardware design was decoupled from the software ...
  • Cálculos electromagnéticos en 3 dimensiones mediante el método de los elementos de contorno 

    Cruellas Ibarz, Juan Carlos; Ferrando Bataller, Miquel (1990)
    Conference report
    Open Access
    The Boundary Element Method is applied to solve 3 D electromagnetic problems. The basic formulation and associated items (integral equation to solve, surface discretization, fields interpolation and numerical integration) ...
