  • Fadhil, Ahmed; AbuRa’ed, Ahmed (ACL (Association for Computational Linguistics), 2019)
    We introduce OlloBot, an Arabic conver-sational agent that assists physicians andsupports patients with the care process.It doesn’t replace the physicians, insteadprovides health tracking and support andassists ...
  • Andriyanova, Iryna; Biglieri, Ezio; Boutros, Joseph Jean (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    This paper presents our investigation on iterative/ndecoding performances of some sparse-graph codes on block-fading Rayleigh channels. The considered code ensembles are standard LDPC codes and Root-LDPC codes, first ...
  • Ferraro, Andrés; Lemström, Kjell (ACM Association for Computer Machinery, 2018)
    The importance of repetitions in music is well-known. In this paper, we study music repetitions in the context of effective and efficient automatic genre classification in large-scale music-databases. We aim at enhancing ...
  • Galdran, Adrian; Bria, Alessandro; Álvarez-Gila, Aitor; Vazquez-Corral, Javier; Bertalmío, Marcelo (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Image dehazing deals with the removal of undesired lossof visibility in outdoor images due to the presence of fog.Retinex is a color vision model mimicking the ability ofthe Human Visual System to robustly discount varying ...
  • Farrús, Mireia; Garde, Ainara; Ejarque, Pascual; Luque, Jordi; Hernando, Javier (International Speech Communication Association (ISCA), 2006)
    Comunicació presentada a: 9th International Conference on Spoken Language Processing; 17-21 de setembre de 2006 a Pittsburgh, Estats Units d'Amèrica
  • Sukno, Federico Mateo; Rojas, Mario A.; Waddington, John L.; Whelan, Paul F. (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    We address a systematic evaluation of facial asymmetry from a population of 100 high-quality laser scans, which are first symmetrized and then manipulated to introduce 25 synthetic patterns with a variety of asymmetries. ...
  • Domínguez Bajo, Mónica; Burga Díaz, Alicia; Farrús, Mireia; Wanner, Leo (CEUR Workshop Proceedings, 2018)
    Conversational technologies that assist elderly people need to adapt to common disabilities in old age. Visual, hearing and even more so cognitive impairments pose serious difficulties for our seniors to handle a standard ...
  • 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, we ...
  • 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 Julià, 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 ...
  • Gómez Marín, Daniel; Jordà Puig, Sergi; Herrera Boyer, Perfecto, 1964- (International Society for Music Information Retrieval (ISMIR), 2015)
    Measuring rhythm similarity is relevant for the analysis and generation of music. Existing similarity metrics tend to consider our perception of rhythms as being in time without discriminating the importance of some ...
  • 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 ...
