  • Farrús, Mireia; Costa-jussà, Marta R.; Mariño Acebal, José B.; Fonollosa, José A Rodriguez (European Association for Machine Translation, 2010)
    Machine translation evaluation methods are highly necessary in order to analyze the performance of translation systems. Up to now, the most traditional methods are the use of automatic measures such as BLEU or the quality ...
  • Farrús, Mireia; Costa-jussà, Marta R. (Oxford University Press, 2015)
    When evaluating machine translation outputs, linguistics is usually taken into account implicitly. Annotators have to decide whether a sentence is better than another or not, using, for example, adequacy and fluency ...
  • Serra, Xavier (International Computer Music Conference, 2005)
    In this article I give a personal view on what could be a roadmap for the research in Music Technology. I will describe the context of this research, the current state of the art, the challenges that lie ahead and I will ...
  • Serra, Xavier (International Computer Music Conference, 2004)
    The Music Technology Group, MTG, integrated in the Audiovisual Institute of the Universitat Pompeu Fabra of Barcelona, specializes in audio processing technologies and their music and multimedia applications. With more ...
  • 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 ...
  • Hazan, Amaury; Marxer Piñón, Ricard; Brossier, Paul; Purwins, Hendrick; Herrera Boyer, Perfecto; Serra, Xavier (Taylor & Francis (Routledge), 2009)
    A causal system to represent a stream of music into musical events, and to generate further expected events, is presented. Starting from an auditory front-end that extracts low-level (i.e. MFCC) and mid-level features such ...
  • Marques, Ricardo; Bouville, Christian; Bouatouch, Kadi (Wiley, 2018)
    This paper proposes optimal quadrature rules over the hemisphere for the shading integral. We leverage recent work regarding the theory of quadrature rules over the sphere in order to derive a new theoretical framework ...
  • Grimaldi, Antoine Vincent; Kane, David; Bertalmío, Marcelo (2017)
    The human visual system (HVS) has evolved to cope with the natural world. Understanding the statistical regularities in the world can help us understanding the HVS and aid the design of image processing algorithms.
  • Amarasinghe, Ishari; Hernández Leo, Davinia; Jonsson, Anders (2017)
    Learner group formation manually based on multiple criteria often fails due to its complexity and time limitations of practitioners. This paper presents a novel binary integer programming approach which models learner ...
  • Pasarella, Edelmira; Lobo, Jorge (ACM Association for Computer Machinery, 2017)
    Relationships like friendship to limit access to resources have been part of social network applications since their beginnings. Describing access control policies in terms of relationships is not particular to social ...
  • Gilson, Matthieu; Tauste Campo, Adrià; Chen, X.; Thiele, Alexander; Deco, Gustavo (MIT Press, 2017)
    Directed connectivity inference has become a cornerstone in neuroscience to analyze multivariate data from neuroimaging and electrophysiological techniques. Here we propose a nonparametric significance method to test the ...
  • Rach, Niklas; Minker, Wolfgang; Wanner, Leo (CEUR Workshop Proceedings, 2017)
    In this work we propose a scheme for an Argumentative Dialogue System that allows a user to discuss a certain topic with a virtual agent using natural language. Starting from an agent vs agent case, we address the ...
  • Bouayad-Agha, Nadjet; Casamayor, Gerard; Mille, Simon; Wanner, Leo (ACM Association for Computer Machinery, 2012)
    Team sports commentaries call for techniques that are able to select content and generate wordings to reflect the affinity of the targeted reader for one of the teams. The existing works tend to have in common that ...
  • Michos, Konstantinos; Hernández Leo, Davinia; Jiménez-Morales, Manel (9) (CEUR Workshop Proceedings, 2017)
    A range of data analytics is provided to educators about the profile, behavior and satisfaction of students participating in a Massive Open Online Course (MOOC). However, limited research has been conducted on how ...
  • Derkach, Dmytro; Sukno, Federico Mateo (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    We investigate the problem of facial expression recognition using 3D data. Building from one of the most successful frameworks for facial analysis using exclusively 3D geometry, we extend the analysis from a curve-based ...
  • Aragón, Pablo; Gómez, Vicenç; Kaltenbrunner, Andreas (Wiley, 2017)
    Online discussions are the essence of many social platforms on the Internet. These platforms are receiving increasing interest because of their potential to become deliberative spaces. Many studies have proposed approaches ...
