  • Farrús, Mireia; Wagner, Michael; Anguita, Jan; Hernando, Javier (International Speech Communication Association (ISCA), 2008)
    Voice imitation is one of the potential threats to security systems that use automatic speaker recognition. Since prosodic features have been considered for state-of-the-art recognition systems in recent years, the question ...
  • Espinosa-Anke, Luis; Ronzano, Francesco; Saggion, Horacio (Springer, 2015)
    Hypernym extraction is a crucial task for semantically motivated NLP tasks such as taxonomy and ontology learning, textual entailment or paraphrase identification. In this paper, we describe an approach to hypernym extraction ...
  • Albó Pérez, Laia; Hernández Leo, Davinia (Springer, 2018)
    Despite the existing variety of learning design tools, there is a gap in their understanding and adoption by the educators in their everyday practices. Sharing is one of the main pillars of learning design but sometimes ...
  • Hernández Leo, Davinia; Asensio-Pérez, Juan I.; Derntl, Michael; Prieto, Luis P.; Chacón Pérez, Jonathan, 1986- (Springer, 2014)
    This demonstration paper presents the Integrated Learning Design Environment (ILDE). ILDE is being developed in the METIS project, which aims at promoting the adoption of learning design by providing integrated support to ...
  • Vazquez-Corral, Javier; Zamir, Syed Waqas; Galdran, Adrian; Pardo, David; Bertalmío, Marcelo (The Society for Imaging Science and Technology (IS&T), 2016)
    The retinex theory of color vision has been a light of inspiration for color researchers since its inception 50 years ago. It has been adapted to work for different goals such as shadow removal, high dynamic range imaging, ...
  • Janer Mestres, Jordi; Gómez Gutiérrez, Emilia, 1975-; Martorell Domínguez, Agustín; Miron, Marius; de Wit, Benjamin (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    This paper combines Audio Signal Processing and Virtual Reality (VR) content to create novel immersive experiences for orchestral music audiences. In VR, the auralization of sound sources of recorded live content remains ...
  • Qasrawi, Radwan Fayez Hasan; Ivorra Cano, Antoni, 1974- (Springer, 2015)
    Electroporation is the phenomenon in which cell membrane permeability is increased by exposing the cell to high intensity electric fields. In living tissues, such permeabilization boost can be used in order to enhance the ...
  • George, Geordie; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    We study the impact of signal reflections in enclosed/nwireless networks of wearable devices operating at mmWave/nfrequencies. Given the radical blockage by obstacles and people/n(including the user’s own body) at these ...
  • Blat, Josep; Evans, Alun Thomas; Agenjo, Javier; Kim, Hansung; Imre, Evren; Hilton, Adrian; Tefas, Anastasios; Nikolaidis, Nikos; Pitas, Ioannis; Polok, Lukas; Smrz, Pavel; Zemcik, Pavel (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    A typical high-end film production generates several terabytes of data per day, either as footage from multiple cameras or as background information regarding the set (laser scans, spherical captures, etc). The EU project ...
  • Moreno, Verónica; Infante, Jorge; Hernández Leo, Davinia (2009-10-04)
    Teniendo en cuenta la importancia del uso del inglés en la cotidianeidad del desempeño profesional del Ingeniero en Telecomunicaciones se ha diseñado un proyecto de innovación docente fundamentado en la inmersión de los ...
  • Wilhelmi Roca, Francesc; Bellalta, Boris; Cano Bastidas, Cristina; Jonsson, Anders, 1973- (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    Reinforcement Learning is gaining attention by the wireless networking community due to its potential to learn good-performing configurations only from the observed results. In this work we propose a stateless variation ...
  • Ballesteros, Miguel; Dyer, Chris; Smith, Noah A. (ACL (Association for Computational Linguistics), 2015)
    We present extensions to a continuousstate dependency parsing method that makes it applicable to morphologically rich languages. Starting with a highperformance transition-based parser that uses long short-term memory ...
  • Farrús, Mireia; Costa-jussà, Marta R.; Poch, Marc; Hernández, Adolfo; Mariño Acebal, José B. (European Association for Machine Translation, 2009)
    In this paper, a human evaluation of a Catalan-Spanish Ngram-based statistical machine translation system is used to develop specific techniques based on the use of grammatical categories, lexical categorisation and text ...
  • Parekh, Sanjeel; Font Corbera, Frederic; Serra, Xavier (Institute of Electrical and Electronics Engineers (IEEE), 2016)
