  • Dzhambazov, Georgi Bogomilov; Srinivasamurthy, Ajay; Sentürk, Sertan; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2016)
    Lyrics-to-audio alignment aims to automatically match given lyrics and musical audio. In this work we extend a state of the art approach for lyrics-to-audio alignment with information about note onsets. In particular, ...
  • Marichal, Sebastián; Malaisé, Adrien; Modugno, Valerio; Dermy, Oriane; Charpillet, François; Ivaldi, Serena (Springer, 2016)
    In this paper we study the relation between the performance of use and user preferences for a robotic arm control interface. We are interested in the user preference of non-experts after a one-shot evaluation of the ...
  • Aragón, Pablo; Sáez-Trumper, Diego; Redi, Miriam; Hale, Scott A.; Gómez, Vicenç; Kaltenbrunner, Andreas (Association for the Advancement of Artificial Intelligence (AAAI), 2018)
    The Internet has become a fundamental resource for activism as it facilitates political mobilization at a global scale. Petition platforms are a clear example of how thousands of people around the world can contribute ...
  • Meditskos, Georgios; Kontopoulos, Efstratios; Vrochidis, Stefanos; Kompatsiaris, Ioannis (CEUR Workshop Proceedings (CEUR-WS.org), 2016)
    In this paper we present a framework for conversational awareness and conflict resolution in spoken dialogue systems for home care assistance. Conver-sational awareness is supported through OWL ontologies for capturing ...
  • Speck, René; Röder, Michael; Oramas, Sergio; Espinosa-Anke, Luis; Ngonga Ngomo, Axel-Cyrille (Springer, 2017)
    The Open Knowledge Extraction Challenge invites researchers and practitioners from academia as well as industry to compete to the aim of pushing further the state of the art of knowledge extraction from text for the Semantic ...
  • Serra, Xavier (Universitat Pompeu Fabra, 2012)
    The current research in Music Information Retrieval (MIR) is showing the potential that the Information Technologies can have in music related applications. A/nmajor research challenge in that direction is how to ...
  • Cyriac, Praveen; Kane, David; Bertalmío, Marcelo (The Society for Imaging Science and Technology (IS&T), 2016)
    The sensor values captured by a digital camera are transformed in a non-linear manner prior to quantization in order to make the quantization rate approximately proportional to the sensitivity of the human visual system. ...
  • George, Geordie; Mungara, Ratheesh K.; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    This paper addresses the benefits of introducing exclusion regions around both transmitters and receivers in D2D wireless networks. Such exclusion regions offer protection from interference at the expense of a sparser ...
  • Lozano Solsona, Angel; Jindal, Nihar (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    The optimization of the pilot overhead in wireless fading channels is investigated, and the dependence of this overhead on various system parameters of interest (e.g., fading rate, signal-to-noise ratio) is quantified. The ...
  • Andriyanova, Iryna; Biglieri, Ezio; Boutros, Joseph Jean (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    This paper derives approximations allowing the estimation of outage probability for standard irregular LDPC codes and full-diversity Root-LDPC codes used over nonergodic block-fading channels. Two separate approaches are ...
  • Serrà, Joan; Surís, Dídac; Miron, Marius; Karatzoglou, Alexandros (Proceedings of Machine Learning Research, 2018)
    Catastrophic forgetting occurs when a neural network loses the information learned in a previous task after training on subsequent tasks. This problem remains a hurdle for artificial intelligence systems with sequential ...
  • Wright, Matthew; Dannenberg, Roger; Pope, Stephen; Rodet, Xavier; Serra, Xavier; Wessel, David (International Computer Music Conference, 2004)
    This panel discussion will review the standards that the computer music community has produced and how these standards were created, followed by a guided interactive group discussion about future directions for our ...
  • Peiró-Lilja, Àlex; Farrús, Mireia (International Speech Communication Association (ISCA), 2018)
    Speech synthesis has reached a reasonable high quality in recent years. However, there is still room for improvement in terms of naturalness and expressiveness when dealing with large multisentential discourse, since ...
  • Farrús, Mireia; Lai, Catherine; Moore, Johanna D. (International Speech Communication Association, 2016)
    Speech synthesis has improved in both expressiveness and voice quality in recent years. However, obtaining full expressiveness when dealing with large multi-sentential synthesized discourse is still a challenge, since ...
  • Smith, Julius O.; Serra, Xavier (International Computer Music Conference, 1987)
    This paper describes a peak-tracking spectrum analyzer, called PARSHL, which is useful for extracting additive synthesis parameters from inharmonic sounds such as the piano. PARSHL is based on the Short-Time Fourier Transform ...
  • Malinverni, Laura; Mora Guiard, Joan; Padillo, Vanesa; Mairena, Maria Angeles; Hervás, Amaia; Parés, Narcís, 1966- (ACM Association for Computer Machinery, 2014)
    In recent years there has been an increasing awareness about the importance of involving children with special needs in the process of designing technology. Starting from this perspective, the paper presents the participatory ...
  • Srinivasamurthy, Ajay; Holzapfel, Andre; Cemgil, Ali Taylan; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2015)
    Recent approaches in meter tracking have successfully applied Bayesian models. While the proposed models can be adapted to different musical styles, the applicability of these flexible methods so far is limited because ...
  • Ferrés, Daniel; Saggion, Horacio; Ronzano, Francesco; Bravo Serrano, Àlex, 1984- (2018)
    The availability of automated approaches and tools to extract structured textual content from PDF articles is essential to enable scientific text mining. This paper describes and evaluates the PDFdigest tool, a PDF-to-XML ...
  • Cyriac, Praveen; Kane, David; Bertalmío, Marcelo (The British Machine Vision Association (BMVA), 2015)
    Digital cameras apply a non-linearity to the captured sensor values prior to quantisation. This process is known as perceptual linearisation and ensures that the quantisation rate is approximately proportional to human ...
  • Bertalmío, Marcelo; Vazquez-Corral, Javier (Color Science Association of Japan (CSAJ), 2015)
    Gamut mapping transforms the color of an input image within the range of a target device. A huge amount of research has been devoted to two subproblems that arise from this general one: gamut reduction and gamut extension. ...
