  • Silberer, Carina; Lapata, Mirella (ACL (Association for Computational Linguistics), 2012)
    A popular tradition of studying semantic representation has been driven by the assumption that word meaning can be learned from the linguistic environment, despite ample evidence suggesting that language is grounded in ...
  • Silberer, Carina; Frank, Anette (ACL (Association for Computational Linguistics), 2012)
    Linking implicit semantic roles is a challenging problem in discourse processing. Unlike prior work inspired by SRL, we cast this problem as an anaphora resolution task and embed it in an entity-based coreference ...
  • Silberer, Carina; Ferrari, Vittorio; Lapata, Mirella (ACL (Association for Computational Linguistics), 2013)
    We consider the problem of grounding the meaning of words in the physical world and focus on the visual modality which we represent by visual attributes. We create a new large-scale taxonomy of visual attributes covering ...
  • Silberer, Carina; Ferrari, Vittorio; Lapata, Mirella (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    In this paper we address the problem of grounding distributional representations of lexical meaning. We introduce a new model which uses stacked autoencoders to learn higher-level representations from textual and visual ...
  • Insabato, Andrea; Pannunzi, Mario; Deco, Gustavo (Public Library of Science (PLoS), 2017)
    The uncertain option task has been recently adopted to investigate the neural systems underlying the decision confidence. Latterly single neurons activity has been recorded in lateral intraparietal cortex of monkeys ...
  • Hyafil, Alexandre; Moreno-Bote, Rubén (eLife, 2017)
    Possible options in a decision often organize as a hierarchy of subdecisions. A recent study concluded that perceptual processes in primates mimic this hierarchical structure and perform subdecisions in parallel. We argue ...
  • Herrera Boyer, Perfecto, 1964-; Gómez Gutiérrez, Emilia, 1975- (Asociación Española de Documentación Musical, 2010)
    Hace un par de décadas el conocer, organizar y explotar la información musical contenida en un archivo sonoro solo era posible a partir de un etiquetado manual que requería la intervención humana para anotar, de manera ...
  • Gómez Gutiérrez, Emilia, 1975- (Ohio State University School of Music, 2008)
    The automatic analysis of large musical corpora by means of computational models overcomes some limitations of manual analysis, and the unavailability of scores for most existing music makes necessary to work with audio ...
  • Jordà Puig, Sergi (MIT Press, 2002)
    The design of new instruments and controllers for performing live computer music is an exciting field of research that can lead to truly new music-making paradigms. The ever-increasing availability of sensing technologies ...
  • Gouyon, Fabien; Dixon, Simon (MIT Press, 2005)
    Rhythm belongs with harmony, melody and timbre as one of the most fundamental aspects of music. Sound by its very nature is temporal, and in its most generic sense, the word \textit{rhythm} is used to refer to all of the ...
  • Leguia, Marc G.; Martínez, Cristina G. B.; Malvestio, Irene; Tauste Campo, Adrià; Rocamora, Rodrigo; Levnajić, Zoran; Andrzejak, Ralph Gregor (American Physical Society, 2019)
    Inferring the topology of a network using the knowledge of the signals of each of the interacting units is key to understanding real-world systems. One way to address this problem is using data- driven methods like ...
  • 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 ...
  • Balasubramani, Pragathi P.; Moreno Bote, Rubén; Hayden, Benjamin Y. (Frontiers, 2018)
    The brain uses a mixture of distributed and modular organization to perform computations and generate appropriate actions. While the principles under which the brain might perform computations using modular systems have ...
  • Moreno Bote, Rubén; Drugowitsch, Jan (Nature Research, 2015)
    While the brain uses spiking neurons for communication, theoretical research on brain computations has mostly focused on non-spiking networks. The nature of spike-based algorithms that achieve complex computations, such ...
  • Ressel, Volker; Pallier, Christophe; Ventura-Campos, Noelia; Díaz, Begoña; Roessler, Abeba; Ávila, César; Sebastián Gallés, Núria (Society for Neuroscience, 2012)
    Two studies (Golestani et al., 2007; Wong et al., 2008) have reported a positive correlation between the ability to perceive foreign speech sounds and the volume of Heschl's gyrus (HG), the structure that houses the auditory ...
  • Toro Soto, Juan Manuel, 1976-; Crespo Bojorque, Paola, 1985- (The Comparative Cognition Society, 2017)
    Consonance is a major feature in harmonic music that has been related to how pleasant a sound is perceived. Consonant chords are defined by simple frequency ratios between their composing tones, whereas dissonant chords ...
  • Cabral, Joana R. B.; Vidaurre, Diego; Marques, Paulo; Magalhães, Ricardo; Moreira, Pedro Silva; Soares, José Miguel; Deco, Gustavo; Sousa, Nuno; Kringelbach, Morten L. (Nature Research, 2017)
    Growing evidence has shown that brain activity at rest slowly wanders through a repertoire of different states, where whole-brain functional connectivity (FC) temporarily settles into distinct FC patterns. Nevertheless, ...
  • Domínguez Bajo, Mónica (Sociedad Española para el Procesamiento del Lenguaje Natural (SEPLN), 2019)
    Tesis doctoral en tecnologías de la información y las comunicaciones realizada por Mónica Domínguez Bajo en la Universidad Pompeu Fabra bajo la dirección del Dr. Leo Wanner y la Dra. Mireia Farrús Cabecerán. El acto de ...
  • Bertalmío, Marcelo; Vazquez-Corral, Javier (Elsevier, 2018)
    Gamut mapping transforms the color gamut of an image to that of a target device. Two cases are usually considered: gamut reduction (target gamut smaller than source gamut), and gamut extension (target gamut larger than ...
  • Pallarés, Vicente; Insabato, Andrea; Sanjuán, Ana; Kühn, Simone; Mantini, Dante; Deco, Gustavo; Gilson, Matthieu (Elsevier, 2018)
    The study of brain communication based on fMRI data is often limited because such measurements are a mixture of session-to-session variability with subject- and condition-related information. Disentangling these contributions ...
