Recent Submissions

  • Di Pietro, Roberto; Oligeri, Gabriele; Salleras Soler, Xavier; Signorini, Matteo (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    In this paper we propose N-Guard: a portable, effective, and efficient solution to thwart contactless skimming of NFC cards. Our solution enables an NFC-compliant smartphone to protect the user's cards, preventing the ...
  • Di Pietro, Roberto; Salleras Soler, Xavier; Signorini, Matteo; Waisbard, Erez (ACM Association for Computer Machinery, 2018)
    One of the biggest challenges for the Internet of Things (IoT) is to bridge the currently fragmented trust domains. The traditional PKI model relies on a common root of trust and does not fit well with the heterogeneous ...
  • Daza, Vanesa; Salleras Soler, Xavier (SciTePress. Science and Technology Publications, 2019)
    Since Remote Keyless Entry (RKE) systems started to be widely used, several vulnerabilities in their protocols have been found. Attacks such as jamming-and-replay attacks and relay attacks are still effective against most ...
  • Truong, Kien T.; Lozano Solsona, Angel; Heath, R. W., Jr. (UNLISTED PUBLISHERVDE Verlag, 2014)
    Massive multiple-input multiple-output (MIMO) communication promises the full potential of MIMO communication realized through the deployment of hundreds of antennas at each base station. Accurate channel state information ...
  • Triay, Joan; Minguillón, Julià; Sancho Vinuesa, Teresa; Daza, Vanesa (CEUR Workshop Proceedings, 2016)
    The huge amount of gathered data in a MOOC allows providing professors and course managers with insightful information about real course usage and consumption. The main aim of this work is to explore how efficient ...
  • Sukno, Federico Mateo; Aspandi, Decky; Martínez, Oriol; Sukno, Federico Mateo; Binefa i Valls, Xavier (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Human facial tracking is an important task in computer vision, which has recently lost pace compared to other facial analysis tasks. The majority of current available tracker possess two major limitations: their little use ...
  • Carrascosa Zamacois, Marc (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    WiFi densification leads to the existence of multiple overlapping coverage areas, which allows user stations (STAs) to choose between different Access Points (APs). The standard WiFi association method makes the STAs select ...
  • Korzeniowski, Filip; Nieto Caballero, Oriol; McCallum, Matthew C.; Won, Minz; Oramas, Sergio; Schmidt, Erik M. (International Society for Music Information Retrieval (ISMIR), 2020)
    The mood of a song is a highly relevant feature for exploration and recommendation in large collections of music. These collections tend to require automatic methods for predicting such moods. In this work, we show that ...
  • Doras, Guillaume; Yesiler, Furkan; Serrà Julià, Joan; Gómez Gutiérrez, Emilia, 1975-; Peeters, Geoffroy (International Society for Music Information Retrieval (ISMIR), 2020)
    Recent works have addressed the automatic cover detection problem from a metric learning perspective. They employ different input representations, aiming to exploit melodic or harmonic characteristics of songs and yield ...
  • Serrà Julià, Joan; Yesiler, Furkan; Gómez Gutiérrez, Emilia, 1975- (International Society for Music Information Retrieval (ISMIR), 2020)
    Version identification systems aim to detect different renditions of the same underlying musical composition (loosely called cover songs). By learning to encode entire recordings into plain vector embeddings, recent systems ...
  • Külebi, Baybars; Öktem, Alp; Peiró Lilja, Àlex; Pascual, Santiago; Farrús, Mireia (International Speech Communication Association (ISCA), 2020)
    We present Catotron, a neural network-based open-source speech synthesis system in Catalan. Catotron consists of a sequence-to-sequence model trained with two small opensource datasets based on semi-spontaneous and read ...
  • Peiró Lilja, Àlex; Farrús, Mireia (International Speech Communication Association (ISCA), 2020)
    State-of-the-art end-to-end speech synthesis models have reached levels of quality close to human capabilities. However, there is still room for improvement in terms of naturalness, related to prosody, which is essential ...
  • Petermann, Darius; Chandna, Pritish; Cuesta, Helena; Bonada, Jordi, 1973-; Gómez Gutiérrez, Emilia, 1975- (International Society for Music Information Retrieval (ISMIR), 2020)
    Choral singing is a widely practiced form of ensemble singing wherein a group of people sing simultaneously in polyphonic harmony. The most commonly practiced setting for choir ensembles consists of four parts; Soprano, ...
  • Cuesta, Helena; McFee, Brian; Gómez Gutiérrez, Emilia, 1975- (International Society for Music Information Retrieval (ISMIR), 2020)
    This paper addresses the extraction of multiple F0 values from polyphonic and a cappella vocal performances using convolutional neural networks (CNNs). We address the major challenges of ensemble singing, i.e., all melodic ...
  • Chandna, Pritish; Cuesta, Helena; Gómez Gutiérrez, Emilia, 1975- (International Society for Music Information Retrieval (ISMIR), 2020)
    Unison singing is the name given to an ensemble of singers simultaneously singing the same melody and lyrics. While each individual singer in a unison sings the same principle melody, there are slight timing and pitch ...
  • Nadeu Camprubí, Climent; Mariño Acebal, José B.; Farrús, Mireia (2007)
    This paper describes a teaching experience. In spring 2006, a new optional course about engineering and responsibility was started at the Universitat Politècnica de Catalunya. Its methodology was mainly based on preparation ...
  • Farrús, Mireia; Iglesias, Gonzalo; Henríquez, Carlos; Poch, Marc; Muñoz, Roberto; Ezeiza, Nerea; Banga, Eduardo R.; Mariño Acebal, José B. (2009)
    Statistical machine translation systems between Spanish and other regional languages from Spain has become an interest of research during the last decade. However, regional languages are usually characterized by the lack ...
  • Costa-jussà, Marta R.; Farrús, Mireia; Serrano Pons, Jordi (2012)
    Machine translation is evolving quite rapidly in terms of quality. Nowadays, we have several machine translation systems available in the web, which provide reasonable translations. However, these systems are not perfect, ...
  • Zinemanas, Pablo; Hounie, Ignacio; Cancela, Pablo; Font, Frederic; Rocamora, Martín; Serra, Xavier (Detection and Classication of Acoustic Scenes and Events (DCASE), 2020)
    This document presents DCASE-models, an open–source Python library for rapid prototyping of environmental sound analysis systems, with an emphasis on deep–learning models. Together with a collection of functions for ...
  • Daza, Vanesa; González, Alonso; Pindado, Zaira; Ràfols, Carla; Silva, Javier (Springer, 2019)
    Despite recent advances in the area of pairing-friendly Non-Interactive Zero-Knowledge proofs, there have not been many efficiency improvements in constructing arguments of satisfiability of quadratic (and larger degree) ...
