  • Zehlike, Meike; Bonchi, Francesco; Castillo, Carlos; Hajian, Sara; Megahed, Mohamed; Baeza-Yates, Ricardo (ACM Association for Computer Machinery, 2017)
    In this work, we define and solve the Fair Top-k Ranking problem, in which we want to determine a subset of k candidates from a large pool of n>>k candidates, maximizing utility (i.e., select the “best” candidates) subject ...
  • Favory, Xavier; Fonseca, Eduardo; Font, Frederic; Serra, Xavier (FRUCT, 2018)
    Properly annotated multimedia content is crucial for supporting advances in many Information Retrieval applications. It enables, for instance, the development of automatic tools for the annotation of large and diverse ...
  • Jindal, Nihar; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    The purpose of this paper is to examine (1) some of the models commonly used to represent fading,/nand (2) the information-theoretic metrics most commonly used to evaluate performance over those models. We raise the question ...
  • Palomares, Roberto P.; Meinhardt Llopis, Enric; Ballester, Coloma; Haro Ortega, Gloria (Springer, 2017)
    We propose a large displacement optical flow method that introduces a new strategy to compute a good local minimum of any optical flow energy functional. The method requires a given set of discrete matches, which can be ...
  • Ivorra Cano, Antoni, 1974-; González-Sosa, Jarold; Ruiz-Vargas, Albert; Arias, Guillem (Elsevier, 2014)
    Pulsed Electric Field technologies have captured the attention of researchers on food/npasteurization because of their non-thermal inactivation mechanism, which results in fresh-like/nproducts. Nevertheless, high voltage ...
  • De Massari, Daniele; Pacheco, Daniel; Malekshahi, Rahim; Betella, Alberto; Verschure, Paul F. M. J.; Birbaumer, Niels; Caria, Andrea (2014)
    The combination of Brain-Computer Interface (BCI) technology, allowing online monitoring and decoding of brain activity, with virtual and mixed reality (MR) systems may help to shape and guide implicit and explicit learning ...
  • Gialampoukidis, Ilias; Vrochidis, Stefanos; Kompatsiaris, Ioannis (Springer, 2016)
    Most of the image retrieval approaches nowadays are based on the Bag-of-Words (BoW) model, which allows for representing an image efficiently and quickly. The efficiency of the BoW model is related to the efficiency of the ...
  • Chamorro Servent, Judit; Aguirre, Juan; Ripoll, Jorge; Vaquero, Juan J.; Deseo, Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    Fluorescence Enhanced Diffuse Optical Tomography (FDOT) retrieves 3D distributions of fluorophore concentration in small animals, non-invasively and in vivo. The FDOT problem can be formulated as a system of equations, ...
  • Chamorro Servent, Judit; Aguirre, Juan; Ripoll, Jorge; Vaquero, Juan J.; Desco, Manuel (Optical Society of America (OSA), 2011)
    When dealing with ill-posed problems such as fluorescence diffuse optical tomography (fDOT) the choice of the regularization parameter is extremely important for computing a reliable reconstruction. Several automatic methods ...
  • Bozkurt, Baris (Universitat Pompeu Fabra, 2012)
    For computational studies of makam music, it is essential to gather a list of characteristics that constitute a makam and explore corresponding quantitative features for automatic/nanalysis. This study is such an attempt ...
  • Cruz-Lemini, Mónica; Crispi Brillas, Fàtima; Valenzuela Alcaraz, Brenda; Figueras, Francesc; Sitges, Marta; Bijnens, Bart; Gratacós Solsona, Eduard (Wiley, 2016)
    Objectives Intrauterine growth restriction is associated with increased cardiovascular risk later in life but the link between fetal disease and postnatal risk is not well‐documented. We evaluated longitudinally the ...
  • Espinosa-Anke, Luis; Oramas, Sergio; Camacho-Collados, Jose; Saggion, Horacio (2016)
    Lexical taxonomies are tree or directed acyclic graph-like structures where each node represents a concept and each edge encodes a binary hypernymic (is-a) relation. These lexical resources are useful for AI tasks like ...
  • Hernández Leo, Davinia; Moreno, Verónica (2014-11-21)
    The role of Bachelors' Final Projects (BFP) in Engineering Education is critical since it offers the opportunity for students to integrate the application of specific and transversal competences they have developed along ...
  • Ceresa, Mario; Kjer, Hans Martin; Vera, Sergio; Carranza, Noemí; Pérez, Frederic; Barazzetti, Livia; Mistrik, Pavel; Dhanasingh, Anandhan; Caversaccio, Marco; Stauber, Martin; Reyes, Mauricio; Paulsen, Rasmus; González Ballester, Miguel Ángel, 1973- (Technical University of Denmark, 2013)
    We present an innovative image analyisis pipeline to perform/npatient-speci c biomechanical and functional simulations of the inner human/near. A high-resolution, cadaveric, mCT volumetric image portraying/nthe detailed ...
  • Becerra-Fajardo, Laura; Ivorra Cano, Antoni, 1974- (Springer, 2018)
    In the past it has been proposed to use implanted electromyography (EMG) sensors for myoelectric control. In contrast to surface systems, these implanted sensors provide signals with low cross-talk. To achieve this, ...
  • Boccardi, Federico; Heath, R. W., Jr.; Lozano Solsona, Angel; Marzetta, Thomas L.; Popovski, Petar (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    New research directions will lead to fundamental changes in the design of future 5th generation (5G)/ncellular networks. This paper describes five technologies that could lead to both architectural and/ncomponent disruptive ...
  • Oramas, Sergio; Gómez, Francisco; Gómez Gutiérrez, Emilia, 1975-; Mora, Joaquín (International Society for Music Information Retrieval (ISMIR), 2015)
    Online information about flamenco music is scattered over different sites and knowledge bases. Unfortunately, there is no common repository that indexes all these data. In this work, information related to flamenco ...
  • Abascal, Juan F.P.J.; Chamorro Servent, Judit; Aguirre, Juan; Arridge, Simon; Correia, Teresa; Ripoll, Jorge; Vaquero, Juan J.; Desco, Manuel (American Association of Physicists in Medicine, 2011)
    Purpose: Standard image reconstruction methods for fluorescence Diffuse Optical Tomography (fDOT) generally make use of L2-regularization. A better choice is to replace the L2 by a total variation functional that effectively ...
