  • Malinverni, Laura; Valero, Cristina; Schaper, Marie-Monique; Garcia de la Cruz, Isabel (Elsevier, 2021)
    Educational robotics has become each time more present in the educational experiences of children and young people. Nonetheless, often, the way in which robotics is introduced in educational settings has been considered ...
  • Coşandal, Ismail; Koca, Mutlu; Biglieri, Ezio; Sari, Hikmet (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Non-orthogonal multiple access (NOMA) is an emerging technique promising to accommodate the increasing data rate requirements of next generation networks. In power-domain (PD) NOMA, this challenge is addressed by allocating ...

    Determining the meanings of words requires language learners to attend to what other people say. However, it behooves a young language learner to simultaneously encode relevant non-verbal cues, for example, by following ...
  • Mosayebi, Reza; Mojahedian, Mohammad Mahdi; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2021)
    Drawing on the notion of parallel interference cancellation, this paper formulates a one-shot linear receiver for the uplink of centralized, possibly cloud-based, radio access networks (C-RANs) operating in a cell-free ...
  • Nikbakht, Rasoul; Jonsson, Anders, 1973-; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2021)
    This letter applies a feedforward neural network trained in an unsupervised fashion to the problem of optimizing the transmit powers in cellular wireless systems. Both uplink and downlink are considered, with either ...
  • Nikbakht, Rasoul; Jonsson, Anders, 1973-; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2021)
    This letter applies a feedforward neural network trained in an unsupervised fashion to the problem of optimizing the transmit powers in centralized radio access networks operating on a cell-free basis. Both uplink and ...
  • Nikbakht, Rasoul; Jonsson, Anders, 1973-; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2021)
    This letter proposes the unsupervised training of a feedforward neural network to solve parametric optimization problems involving large numbers of parameters. Such unsupervised training, which consists in repeatedly ...
  • Chandna, Pritish; Blaauw, Merlijn; Bonada, Jordi, 1973-; Gómez Gutiérrez, Emilia, 1975- (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    We present a deep neural network based singing voice synthesizer, inspired by the Deep Convolutions Generative Adversarial Networks (DCGAN) architecture and optimized using the Wasserstein-GAN algorithm. We use vocoder ...
  • Gómez Villa, Alexander; Martín, Adrian; Vazquez-Corral, Javier; Bertalmío, Marcelo (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Visual illusions teach us that what we see is not always what is represented in the physical world. Their special nature make them a fascinating tool to test and validate any new vision model proposed. In general, current ...
  • Velamazán, Mariano; Santos Rodríguez, Patrícia; Hernández Leo, Davinia (CEUR Workshop Proceedings, 2020)
    This paper analyses a gamified collaborative formal–informal outdoor activity and uses the findings to inform the design of future mobile collaboration tools. We present a case study framed in two editions (in years 2018 ...
  • Barrachina Muñoz, Sergio; Bellalta, Boris; Knightly, Edward (ACM Association for Computer Machinery, 2020)
    In this paper, we present WACA, the first system to simultaneously measure the energy in all 24 Wi-Fi channels that allow channel bonding at 5 GHz with microsecond scale granularity. With WACA, we perform a first-of-its-kind ...
  • Cruzat, Josephine; Torralba, Mireia; Ruzzoli, Manuela; Fernández, Alba; Deco, Gustavo; Soto-Faraco, Salvador, 1970- (Elsevier, 2021)
    Several studies have shown that attention and perception can depend upon the phase of ongoing neural oscillations at stimulus onset. Here, we extend this idea to the memory domain. We tested the hypothesis that ongoing ...
  • Piccinini, Juan; Perez Ipiña, Ignacio; Laufs, Helmut; Kringelbach, Morten L.; Deco, Gustavo; Sanz Perl, Yonatan; Tagliazucchi, Enzo (American Institute of Physics (AIP), 2021)
    An outstanding open problem in neuroscience is to understand how neural systems are capable of producing and sustaining complex spatiotemporal dynamics. Computational models that combine local dynamics with in vivo ...
  • Jiménez Sánchez, Amelia; Mateus, Diana; Kirchhoff, Sonja; Kirchhoff, Chlodwing; Biberthaler, Peter; Navab, Nassir; González Ballester, Miguel Ángel, 1973-; Piella Fenoy, Gemma (Springer, 2019)
    Current deep-learning based methods do not easily integrate to clinical protocols, neither take full advantage of medical knowledge. In this work, we propose and compare several strategies relying on curriculum learning, ...
  • Hurault, Samuel; Ballester, Coloma; Haro Ortega, Gloria (ACM Association for Computer Machinery, 2020)
    In a soccer game, the information provided by detecting and tracking brings crucial clues to further analyze and understand some tactical aspects of the game, including individual and team actions. State-of-the-art tracking ...
  • Charisi, Vicky; Malinverni, Laura; Rubegni, Elisa; Schaper, Marie-Monique (ACM Association for Computer Machinery, 2020)
    The increasing presence of robotics, automated systems, and AI in everyday life is carrying important ethical and social implications for both those who design and develop them as well as for the users. Addressing these ...
