  • Barbieri, Francesco; Ballesteros, Miguel; Ronzano, Francesco; Saggion, Horacio (ACL (Association for Computational Linguistics), 2018)
    Emojis are small images that are commonly included in social media text messages. The combination of visual and textual content in the same message builds up a modern way of communication, that automatic systems are not ...
  • Zimmer, Veronika Anne; González Ballester, Miguel Ángel, 1973-; Piella Fenoy, Gemma (Elsevier, 2019)
    The fusion and combination of images from multiple modalities is important in many applications. Typically, this process consists of the alignment of the images and the combination of the complementary information. In ...
  • Malinverni, Laura; Schaper, Marie-Monique; Parés, Narcís, 1966- (SAGE Publications, 2019)
    Over the past years an increasing number of digital learning environments based on Full-Body Interaction have been developed. Research in this field is often based on Designer-Driven approaches and is only recently employing ...
  • Farrús, Mireia; Luque, Jordi; Morros, R.; Anguita, Jan; Macho, D.; Marqués, Marta; Martínez, C.; Vilaplana, V.; Hernando, Javier (Universidad de Zaragoza, 2006)
    In this paper we present a person identification system based on a combination of acoustic features and 2D face images. We address the modality integration issue on the example of a smart room environment. In order to ...
  • Abramson, Norman; Sacchi, Claudio; Bellalta, Boris; Vinel, Alexey (SpringerOpen, 2012)
  • Zheng, Haitao; Lozano Solsona, Angel; Haleem, Mohamed (Hindawi, 2004)
    We propose a new automatic repeat request (ARQ) scheme for MIMO systems with multiple transmit and receive antennas. The substreams emitted from various transmit antennas encounter distinct propagation channels and thus ...
  • 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 ...
  • Angelosante, Daniele; Biglieri, Ezio; Lops, Marco (European Association for Signal Processing (EURASIP), 2008)
    This paper presents several algorithms for joint estimation of the target number and state in a time-varying scenario. Building on the results presented in [1], which considers estimation of the target number only, we ...
  • Arandía Romero, Iñigo; Tanabe, Seiji; Drugowitsch, Jan; Kohn, Adam; Moreno Bote, Rubén (Elsevier, 2016)
    Numerous studies have shown that neuronal re- sponses are modulated by stimulus properties and also by the state of the local network. However, little is known about how activity fluctuations of neuronal populations ...
  • Saggion, Horacio; Ronzano, Francesco; Accuosto, Pablo; Ferrés, Daniel (CEUR Workshop Proceedings, 2017)
    In the current online Open Science context, scientific datasets and tools for deep text analysis, visualization and exploitation play a major role.We present a system for deep analysis and annotation of scientific text ...
  • Vrochidis, Stefanos; Kompatsiaris, Ioannis; Casamayor, Gerard; Arapakis, Ioannis; Busch, Reinhard; Alexiev, Vladimir; Jamin, Emmanuel; Jugov, Michael; Heise, Nicolaus; Forrellat, Teresa; Liparas, Dimitris; Wanner, Leo (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    This paper presents an overview and the first results of the FP7 MULTISENSOR project, which deals with multidimensional content integration of multimedia content for intelligent sentiment enriched and context ...
  • Scarlett, Jonathan; Martinez, Alfonso; Guillén i Fàbregas, Albert (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    This paper studies multiuser coding techniques for channel coding with a given (possibly suboptimal) decoding rule. For the mismatched discrete memoryless multiple-access channel, error exponents are obtained which are ...
  • Angelosante, Daniele; Biglieri, Ezio; Lops, Marco (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    The problem of jointly estimating the number, the identities, and the data of active users in a time-varying multiuser environment was examined in a companion paper (IEEE Trans. Information Theory, vol. 53, no. 9, September ...
  • Angelosante, Daniele; Biglieri, Ezio; Lops, Marco (European Association for Signal Processing (EURASIP), 2008)
    In multiuser detection, the set of users active at any time may be unknown to the receiver. In these conditions, optimum reception consists of detecting simultaneously the set of active/nusers and their data, problem that ...
  • Scarlett, Jonathan; Martinez, Alfonso; Guillén i Fàbregas, Albert (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    This paper studies multiuser random coding techniques for channel coding with a given (possibly suboptimal) decoding rule. For the mismatched discrete memoryless multiple-access channel, an error exponent is obtained that ...
  • Salselas, Inês; Herrera Boyer, Perfecto, 1964- (Ubiquity Press, 2011)
    In the present study we aim to capture rhythmic and melodic patterning in speech and singing directed to infants. We address this issue by exploring the acoustic features that best predict different classification problems. ...
  • Schedl, Markus; Gómez Gutiérrez, Emilia, 1975-; Urbano, Julián (Now Publishers Inc., 2014)
    We provide a survey of the field of Music Information Retrieval (MIR), in particular paying attention to latest developments, such as semantic auto-tagging and user-centric retrieval and recommendation approaches. We first ...
  • Nogueira, Waldo; Haro Berois, Martín; Herrera Boyer, Perfecto, 1964-; Serra, Xavier (ACM Association for Computer Machinery, 2011)
    This work presents a brief review on hearing with cochlear implants with emphasis on music perception. Although speech perception in noise with cochlear implants is still the major challenge, music perception is becoming ...
  • Porcaro, Lorenzo; Castillo, Carlos; Gómez Gutiérrez, Emilia, 1975- (International Society for Music Information Retrieval (ISMIR), 2019)
    Music recommendations are increasingly part of the listening experience of people all over the world, especially in the context of streaming services. In this scenario, recommender systems’ role is to help users in ...
  • Serra, Xavier (International Computer Music Conference, 2000)
    The Audiovisual Institute (http://www.iua.upf.es) is a research center of the Pompeu Fabra University, (http://www.upf.es) located in Barcelona and devoted to new media technologies. Apart from its main research activities, ...
