  • Recalde, Lorena; Baeza Yates, Ricardo (Springer, 2020)
    According to tastes, a person could show preference for a given category of content to a greater or lesser extent. However, quantifying people’s amount of interest in a certain topic is a challenging task, especially ...
  • Samanta, Bidisha; De, Abir; Jana, Gourhari; Gómez, Vicenç; Chattaraj, Pratim Kumar; Ganguly, Niloy; Gomez-Rodriguez, Manuel (Journal of Machine Learning Research, 2020)
    Deep generative models have been praised for their ability to learn smooth latent representations of images, text, and audio, which can then be used to generate new, plausible data. Motivated by these success stories, there ...
  • López-Moliner, Joan; Soto Faraco, Salvador (Association for Research in Vision and Ophthalmology (ARVO), 2007)
    There is a growing body of knowledge about the behavioral and neural correlates of cross-modal interactions in the perception of motion direction, as well as about the computations that underlie unimodal visual speed ...
  • Vigué Guix, Irene; Morís Fernández, Luis, 1982-; Torralba Cuello, Mireia; Ruzzoli, Manuela; Soto Faraco, Salvador (Wiley, 2020)
    Electrical brain oscillations reflect fluctuations in neural excitability. Fluctuations in the alpha band (α, 8–12 Hz) in the occipito‐parietal cortex are thought to regulate sensory responses, leading to cyclic variations ...
  • Roma Trepat, Gerard; Herrera Boyer, Perfecto, 1964-; Zanin, Massimiliano; Toral, Sergio L.; Font Corbera, Frederic; Serra, Xavier (Inderscience Enterprises Ltd, 2012)
    Sharing communities are changing the way audio clips are obtained in several areas, ranging from music to game design. The motivations for people to record and upload sounds to these sites are likely to be related to social ...
  • Tamir, Ran; Merhav, Neri; Weinberger, Nir; Guillén i Fàbregas, Albert (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    This work studies the deviations of the error exponent of the constant composition code ensemble around its expectation, known as the error exponent of the typical random code (TRC). In particular, it is shown that the ...
  • Daza, Vanesa; Ràfols, Carla; Zacharakis, Alexandros (Springer, 2020)
    We propose an improvement for the inner product argument of Bootle et al. (EUROCRYPT’16). The new argument replaces the unstructured common reference string (the commitment key) by a structured one. We give two instantiations ...
  • Morís Fernández, Luis, 1982-; Vadillo, Miguel A. (Royal Society, 2020)
    In the present article, we explore the influence of undisclosed flexibility in the analysis of reaction times (RTs). RTs entail some degrees of freedom of their own, due to their skewed distribution, the potential presence ...
  • Higueras-Esteban, Alfredo; Delgado-Martínez, Ignacio; Serrano, Laura; Principe, Alessandro; Pérez Enríquez, Carmen; González Ballester, Miguel Ángel, 1973-; Rocamora Zúñiga, Rodrigo Alberto; Conesa Bertran, Gerardo; Serra, Luis (Elsevier, 2021)
    Background and objective: We present SYLVIUS, a software platform intended to facilitate and improve the complex workflow required to diagnose and surgically treat drug-resistant epilepsies. In complex epilepsies, additional ...
  • Casanova De Vilalta, Lydia; Theophilou, Emily; Beardsley, Marc; Santos Rodríguez, Patrícia; Hernández Leo, Davinia (2020)
    Efforts are being made to add Computational Thinking (CT) to the curriculum of primary schools in order to develop student abilities to use computational tools to solve problems and better prepare them for an increasingly ...
  • Baeza Yates, Ricardo (ACM Association for Computer Machinery, 2020)
    Social media data is often used to pulse the opinion of online communities, either by predicting sentiment or stances (e.g., political), to mention just two typical use cases. However, those analysis assume that the data ...
  • Lobo, Jorge; Bertino, Elisa; Russo, Alessandra (ACM Association for Computer Machinery, 2020)
    There has been over the past decade a rapid change towards computational environments that are comprised of large and diverse sets of devices, many of them mobile, which can connect in flexible and context-dependent ways. ...
  • Zehlike, Meike; Sühr, Tom; Castillo, Carlos; Kitanovski, Ivan (ACM Association for Computer Machinery, 2020)
    Ranked search results and recommendations have become the main mechanism by which we find content, products, places, and people online. With hiring, selecting, purchasing, and dating being increasingly mediated by algorithms, ...
  • Bogdanov, Dmitry; Herrera, Perfecto (2012)
    In this work we propose a novel approach to music recommendation based exclusively on editorial metadata. To this end, we propose to use a public database of music releases Discogs.com, which contains extensive information ...
  • Zacharaki, Konstantina; Sebastián Gallés, Núria (Elsevier, 2021)
    Infants can discriminate languages that belong to different rhythmic classes at birth. The ability to perform within-class discrimination emerges around the fifth month of life. The cues that infants use to discriminate ...
  • Miró Padilla, Anna; Bueichekú, Elisenda; Adrián Ventura, Jesús; Costumero, Víctor; Palomar García, María Ángeles; Villar Rodríguez, Esteban; Marin-Marin, Lidon; Aguirre, Naiara; Ávila, César (Elsevier, 2021)
    Working memory training causes functional adaptations in the brain, which include changes in activation and functional connectivity that remain stable over time. Few studies have investigated gray matter (GM) changes after ...
  • Martínez Plumed, Fernando; Gómez Gutiérrez, Emilia, 1975-; Hernández-Orallo, José (Elsevier, 2021)
    Artificial Intelligence (AI) offers the potential to transform our lives in radical ways. However, the main unanswered questions about this foreseen transformation are its depth, breadth and timelines. To answer them, not ...
  • Bellalta, Boris (Institute of Electrical and Electronics Engineers (IEEE), 2021)
    This letter analyzes the Low-latency Region (LLR) of a best-effort link (i.e., no traffic differentiation, and first come first serve scheduling) carrying both delay-sensitive (DS) streaming and non-delay-sensitive (NDS) ...
  • Marin-Marin, Lidon; Palomar García, María Ángeles; Miró Padilla, Anna; Adrián Ventura, Jesús; Aguirre, Naiara; Villar Rodríguez, Esteban; Costumero, Víctor (Mary Ann Liebert, Inc, 2021)
    Background: Bilingualism is considered a cognitive reserve (CR) factor, due to the delay in the onset of dementia in bilinguals compared with monolinguals. Two neural mechanisms have been suggested to underlie CR: neural ...
  • Sayago Barrantes, Sergio; Righi, Valeria; Rosales, Andrea; Möller Ferreira, Susan; Blat, Josep (2016)
    By drawing upon slightly more than a decade of research in the field of Human-Computer Interaction / ICT & Ageing, conducted by the authors in adult educational centres and computer clubhouses in European and South American ...
