  • Amarasinghe, Ishari; Hernández Leo, Davinia; Jonsson, Anders (2017)
    Well-structured collaborative learning groups scripted based on Collaborative Learning Flow Patterns (CLFPs) often result in successful collaborative learning outcomes. Formulation of such learner groups based on instructor ...
  • Rach, Niklas; Minker, Wolfgang; Ultes, Stefan (ACL (Association for Computational Linguistics), 2017)
    For estimating the Interaction Quality (IQ) in Spoken Dialogue Systems (SDS), the dialogue history is of significant importance. Previous works included this information manually in the form of precomputed temporal features ...
  • Mungara, Ratheesh K.; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Historically unfeasible because of self-interference, full duplexing has now been experimentally demonstrated and is on the verge of commercial feasibility thanks to advances in self-interference cancellation. This will ...
  • Barbieri, Francesco; Espinosa-Anke, Luis; Camacho-Collados, Jose; Schockaert, Steven; Saggion, Horacio (ACL (Association for Computational Linguistics), 2018)
    Human language has evolved towards newer forms of communication such as social media, where emojis (i.e., ideograms bearing a visual meaning) play a key role. While there is an increasing body of work aimed at ...
  • Hernández Leo, Davinia; Moreno, Verónica (2010-07-22)
    The innovative subject “Introduction to ICT” combines a general Introductory Course to the University with elements around the Information and Communication Technologies sector (including the ICT engineer competence profile, ...
  • Papiotis, Panos; Marchini, Marco, 1984-; Maestre Gómez, Esteban (Associoation Européenne des Conservatoires, 2013)
    We present an exploratory study on ensemble expressive performance based on the analysis of string quartet recordings. We recorded a piece with three expressive intentions: mechanical, normal, and exaggerated. We made use ...
  • Kane, David; Bertalmío, Marcelo (Society of Photo Optical Instrumentation Engineers (SPIE), 2015)
    The system gamma of the imaging pipeline, defined as the product of the encoding and decoding gammas, is typically greater than one and is stronger for images viewed with a dark background (e.g. cinema) than those viewed ...
  • Bantula, Helena; Giraldo, Sergio Iván; Ramírez, Rafael,1966- (International Society for Music Information Retrieval (ISMIR), 2016)
    Computational expressive music performance studies the analysis and characterisation of the deviations that a musician introduces when performing a musical piece. It has been studied in a classical context where timing ...
  • Farrús, Mireia (International Speech Communication Association (ISCA), 2007)
    Jitter and shimmer are measures of the cycle-to-cycle variations of fundamental frequency and amplitude, respectively, which have been largely used for the description of pathological voice quality. Since they characterise ...
  • Palomares, Roberto P.; Haro Ortega, Gloria; Ballester, Coloma (SCITEPRESS – Science and Technology Publications, Lda., 2017)
    This paper presents a novel variational approach for the joint estimation of scene flow and occlusions. Our method does not assume that a depth sensor is available. Instead, we use a stereo sequence and exploit the fact ...
  • Prieto, Luis P.; Martínez-Maldonado, Roberto; Spikol, Daniel; Hernández Leo, Davinia; Rodríguez-Triana, María Jesús; Ochoa, Xavier (CEUR Workshop Proceedings, 2017)
    Learning is a complex, mostly invisible process that happens across spaces, occurring in the physical world but also increasingly in virtual worlds or web-based spaces. In order to explore what happens in such blended ...
  • Faraldo Pérez, Ángel; Gómez Gutiérrez, Emilia, 1975-; Jordà Puig, Sergi; Herrera Boyer, Perfecto (Springer, 2016)
    In this paper we study key estimation in electronic dance music, an umbrella term referring to a variety of electronic music subgenres intended for dancing at nightclubs and raves. We start by defining notions of tonality ...
  • Delli Bovi, Claudio; Espinosa-Anke, Luis; Navigli, Roberto (ACL (Association for Computational Linguistics), 2015)
    We present KB-UNIFY, a novel approach for integrating the output of different Open Information Extraction systems into a single unified and fully disambiguated knowledge repository. KB-UNIFY consists of three main steps: ...
  • Ronzano, Francesco; Saggion, Horacio (Springer, 2016)
    During the last decade the amount of scientific articles available online has substantially grown in parallel with the adoption of the Open Access publishing model. Nowadays researchers, as well as any other interested ...
  • Wanner, Leo; André, Elisabeth; Blat, Josep; Dasiopoulou, Stamatia; Farrús, Mireia; Kamateri, Eleni; Lingenfelser, Florian; Llorach, Gerard; Martínez, Oriol; Meditskose, Georgios; Mille, Simon; Minker, Wolfgang; Pragst, Louisa; Schiller, Dominik; Stam, Andries; Stellingwerff, Ludo; Sukno, Federico Mateo; Vieru, Bianca; Vrochidis, Stefanos (Springer, 2017)
    We present an intelligent embodied conversation agent with linguistic, social and emotional competence. Unlike the vast majority of the state-of-the-art conversation agents, the proposed agent is constructed around an ...
  • Oliver, Maria; Haro Ortega, Gloria; Fedorov, Vadim; Ballester, Coloma (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    This paper proposes a novel patch-based variational segmentation method that considers adaptive patches to characterize, in an affine invariant way, the local structure of each homogeneous texture region of the image and ...
  • Gulati, Sankalp; Serrà Julià, Joan; Ganguli, Kaustuv Kanti; Serra, Xavier (2014)
    Musical melodies contain hierarchically organized events, where some events are more salient than others, acting as melodic landmarks. In Hindustani music melodies, an important landmark is the occurrence of a nyas. ...
  • Biglieri, Ezio; Grossi, Emanuele; Lops, Marco; Tauste Campo, Adrià (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    We study the minimum mean square error (MMSE) and the multiuser efficiency η of large dynamic multiple access communication systems in which optimal multiuser detection is performed at the receiver as the number and the ...
  • AbuRa’ed, Ahmed; Chiruzzo, Luis; Saggion, Horacio; Accuosto, Pablo; Bravo Serrano, Àlex, 1984- (2017)
    In recent years there has been an increasing interest in approaches to scienti c summarization that take advantage of the citations a research paper has received in order to extract its main contributions. In this ...
