Recent Submissions

  • Gong, Rong; Serra, Xavier (2017)
    Music Information Retrieval (MIR) technologies have been proven useful in assisting western classical singing training. Jingju (also known as Beijing or Peking opera) singing is different from western singing in terms ...
  • Herold, Gottfried; Hesse, Julia; Hofheinz, Dennis; Ràfols, Carla; Rupp, Andy (Springer, 2014)
    At Eurocrypt 2010, Freeman presented a framework to convert cryptosystems based on composite-order groups into ones that use prime-order groups. Such a transformation is interesting not only from a conceptual point of ...
  • Escala, Alex; Herranz, Javier; Libert, Benoît; Ràfols, Carla (Springer, 2014)
    Lossy trapdoor functions, introduced by Peikert and Waters (STOC’08), have received a lot of attention in the last years, because of their wide range of applications. The notion has been recently extended to the ...
  • Ràfols, Carla (Springer, 2015)
    Groth, Ostrovsky and Sahai constructed a non-interactive Zap for NP-languages by observing that the common reference string of their proof system for circuit satisfiability admits what they call correlated key generation. ...
  • González, Alonso; Hevia, Alejandro; Ràfols, Carla (Springer, 2015)
    A sequence of recent works have constructed constant-size quasi-adaptive (QA) NIZK arguments of membership in linear subspaces of ^Gm, where ^G is a group equipped with a bilinear map e : G x H --> T. Although applicable ...
  • Morillo, Paz; Ràfols, Carla; Villar, Jorge L. (Springer, 2016)
    We put forward a new family of computational assumptions, the Kernel Matrix Diffi-Hellman Assumption. Given some matrix A sampled from some distribution D, the kernel assumption says that it is hard to find \in the ...
  • Ramires, António; Serra, Xavier (2019)
    Reusing recorded sounds (sampling) is a key component in Electronic Music Production (EMP), which has been present since its early days and is at the core of genres like hip-hop or jungle. Commercial and non-commercial ...
  • Nuñez-Garcia, Marta; Bernardino Perez, Gabriel; Doste, Rubén; Zhao, Jichao; Camara, Oscar; Butakoff, Constantine (Springer, 2019)
    Two-dimensional standard representations of 3D anatomical structures are a simple and intuitive way for analysing patient information across populations and image modalities. They also allow convenient visualizations that ...
  • Nunes, Cecília; De Craene, Mathieu; Langet, Hélène; Camara, Oscar; Jonsson, Anders, 1973- (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Decision trees (DTs) are a widely used prediction tool, owing to their interpretability. Standard learning methods follow a locally-optimal approach that trades off prediction performance for computational efficiency. Such ...
  • Nikbakht, Rasoul; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    This paper proposes a power control policy for the uplink of cell-free wireless networks. Such policy, which generalizes the fractional power control used extensively in cellular networks, relies only on large-scale ...
  • Bozkurt, Baris; Gulati, Sankalp; Romani Picas, Oriol; Serra, Xavier (International Society for Music Education, 2018)
    This paper concerns online music education and as contribution, it proposes a new technological framework to support online music performance teaching to reduce loads on teachers for assessing large number of student ...
  • Bogdanov, Dmitry; Won, Minz Sanghee; Tovstogan, Philip; Porter, Alastair; Serra, Xavier (2019)
    We present the MTG-Jamendo Dataset, a new open dataset for music auto-tagging. It is built using music available at Jamendo under Creative Commons licenses and tags provided by content uploaders. The dataset contains ...
  • Bogdanov, Dmitry; Porter, Alastair; Schreiber, Hendrik; Urbano, Julián; Oramas, Sergio (International Society for Music Information Retrieval (ISMIR), 2019)
    This paper introduces the AcousticBrainz Genre Dataset, a large-scale collection of hierarchical multi-label genre annotations from different metadata sources. It allows researchers to explore how the same music pieces ...
  • Accuosto, Pablo; Saggion, Horacio (Springer, 2019)
    Argument mining consists in the automatic identification of argumentative structures in texts. In this work we address the open question of whether discourse-level annotations can contribute to facilitate the identification ...
  • Porcaro, Lorenzo; Gómez Gutiérrez, Emilia, 1975- (International Society for Music Information Retrieval (ISMIR), 2019)
    Grouping songs together, according to music preferences, mood or other characteristics, is an activity which reflects personal listening behaviours and tastes. In the last two decades, due to the increasing size of music ...
  • Stowell, Dan; Muševič, Sašo; Bonada, Jordi, 1973-; Plumbley, Mark D. (Institute of Electrical and Electronics Engineers (IEEE), 2013)
    Segregating an audio mixture containing multiple simultaneous bird sounds is a challenging task. However, birdsong often contains rapid pitch modulations, and these modulations carry information which may be of use in ...
  • Smeros, Panayiotis; Castillo, Carlos; Aberer, Karl (ACM Association for Computer Machinery, 2019)
    This paper describes, develops, and validates SciLens, a method to evaluate the quality of scientific news articles. The starting point for our work are structured methodologies that define a series of quality aspects for ...
  • Caro Repetto, Rafael; Serra, Xavier (2016)
    En sus poco más de doscientos años de historia, el jingju, u ópera de Pekín, ha conseguido el título de tesoro nacional (guocui) y como tal ha asumido la turbulenta historia reciente del país. En la puja por situarse como ...
  • Puiggròs, Montserrat; Gómez Gutiérrez, Emilia, 1975-; Ramírez, Rafael,1966-; Serra, Xavier; Bresin, Roberto (Bononia University Press, 2006)
    Expressive performance characterization is traditionally based on the analysis of the main differences between performances, players, playing styles and emotional intentions. This work addresses the characterization of ...
  • Caro Repetto, Rafael; Serra, Xavier (2016)
    Music in jingju (also known as Peking or Beijing opera) is predefined by tradition. Before the appearance of jingju music composers, actors used to “arrange melodies” (bianqu) for new lyrics according to melodic systems ...
