  • Deneux, Thomas; Masquelier, Timothée; Bermudez, Maria A.; Masson, Guillaume S.; Deco, Gustavo; Vanzetta, Ivo (Society of Photo Optical Instrumentation Engineers (SPIE), 2017)
    Increasing evidence suggests that sensory stimulation not only changes the level of cortical activity with respect to baseline but also its structure. Despite having been reported in a multitude of conditions and preparations ...
  • Aragón, Pablo; Gómez, Vicenç; Kaltenbrunner, Andreas (Association for the Advancement of Artificial Intelligence (AAAI), 2016)
    Online debate tools for participatory democracy and crowdsourcing legislation are limited by different factors. One of them arises when discussion of proposals reaches a large number of contributions and therefore ...
  • Soler Company, Juan; Ballesteros, Miguel; Bohnet, Bernd; Mille, Simon; Wanner, Leo (ACL (Association for Computational Linguistics), 2015)
    “Deep-syntactic” dependency structures bridge the gap between the surface-syntactic structures as produced by state-of-the-art dependency parsers and semantic logical forms in that they abstract away from surfacesyntactic ...
  • Öktem, Alp; Farrús, Mireia; Bonafonte, Antonio (International Speech Communication Association (ISCA), 2018)
    We have developed a neural architecture that tests the effect of lexical, morphosyntactic and prosodic features in restoring punctuation in speech transcriptions. Having outperformed a baseline model in terms of precision ...
  • Farrús, Mireia (ACM Association for Computer Machinery, 2018)
    We, humans, are able to identify other people even in voice disguise conditions. However, we are not immune to all voice changes when trying to identifying people from voice. Likewise, automatic speaker recognition systems ...
  • Cano, Pedro; Loscos, Àlex; Bonada, Jordi, 1973-; de Boer, Marteen; Serra, Xavier (International Computer Music Conference, 2000)
    In this paper we present a real-time system for morphing two voices in the context of a karaoke application. As the user sings a pre-established song, his pitch, timbre, vibrato and articulation can be modified to resemble ...
  • Vera, Sergio; González Ballester, Miguel Ángel, 1973-; Gil, Debora (Technical University of Denmark, 2013)
    A coordinate system parameterizing the interior of organs is/na powerful tool for a systematic localization of injured tissue. If the same/ncoordinate values are assigned to speci c anatomical sites, parameterizations/nensure ...
  • Oubel, E.; Cebral, J.R.; De Craene, Mathieu; Blanc, R.; Blasco, Jordi; Macho, Juan M.; Putman, C.M.; Frangi Caregnato, Alejandro (Institute of Physics (IOP), 2010)
    The quantification of wall motion in cerebral aneurysms is becoming important owing to its potential connection to rupture, and as a way to incorporate the effects of vascular compliance in computational fluid dynamics ...
  • Birulés-Muntané, Joan; Soto-Faraco, Salvador, 1970- (Public Library of Science (PLoS), 2016)
    Watching English-spoken films with subtitles is becoming increasingly popular throughout the world. One reason for this trend is the assumption that perceptual learning of the sounds of a foreign language, English, will ...
  • Purwins, Hendrick (Elsevier, 2010)
  • Espinosa-Anke, Luis; Ronzano, Francesco; Saggion, Horacio (ACL (Association for Computational Linguistics), 2015)
    Definition Extraction (DE) is the task to extract textual definitions from naturally occurring text. It is gaining popularity as a prior step for constructing taxonomies, ontologies, automatic glossaries or dictionary ...
  • Llorach, Gerard; Evans, Alun Thomas; Blat, Josep; Grimm, Giso; Hohmann, Volker (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Virtual characters are an integral part of many games and virtual worlds. The ability to accurately synchronize lip movement to audio speech is an important aspect in the believability of the character. In this paper we ...
  • Evans, Alun Thomas; Agenjo, Javier; Blat, Josep (ACM Association for Computer Machinery, 2014)
    In this paper we present a system for progressive encoding, storage, transmission, and web based visualization of large point cloud datasets. Point cloud data is typically recorded on-set during a film production, and is ...
  • Deco, Gustavo; Scarano, Leandro; Soto-Faraco, Salvador, 1970- (Society for Neuroscience, 2007)
    Recent single-cell studies in monkeys (Romo et al., 2004) show that the activity of neurons in the ventral premotor cortex covaries with the animal's decisions in a perceptual comparison task regarding the frequency of ...
  • Arandía Romero, Iñigo; Nogueira Mañas, Ramon; Mochol, Gabriela; Moreno Bote, Rubén (Elsevier, 2017)
    Nowadays, it is possible to record the activity of hundreds of cells at the same time in behaving animals. However, these data are often treated and analyzed as if they consisted of many independently recorded neurons. How ...
  • Chicharro Raventós, Daniel; Kreuz, Thomas; Andrzejak, Ralph Gregor (Elsevier, 2011)
    Time scale parametric spike train distances like the Victor and the van Rossum distances/nare often applied to study the neural code based on neural stimuli discrimination./nDifferent neural coding hypotheses, such as rate ...
  • Iacozza, Sara; Costa, Albert, 1970-; Duñabeitia, Jon Andoni (Public Library of Science (PLoS), 2017)
    Foreign languages are often learned in emotionally neutral academic environments which differ greatly from the familiar context where native languages are acquired. This difference in learning contexts has been argued to ...
  • Barbieri, Francesco; Ronzano, Francesco; Saggion, Horacio (ELRA (European Language Resources Association), 2016)
    Emojis allow us to describe objects, situations and even feelings with small images, providing a visual and quick way to communicate. In this paper, we analyse emojis used in Twitter with distributional semantic models. ...
  • Urbano, Julián; Bogdanov, Dmitry; Herrera Boyer, Perfecto, 1964-; Gómez Gutiérrez, Emilia, 1975-; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2014)
    Music Information Retrieval is largely based on descriptors computed from audio signals, and in many practical applications they are to be computed on music corpora containing audio files encoded in a variety of lossy ...
  • Jindal, Nihar; Lozano Solsona, Angel; Marzetta, Thomas L. (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    The spectral efficiency achievable with joint processing of pilot and data symbol observations is compared with that achievable through the conventional (separate) approach of first estimating the channel on the basis of ...
