  • Scarlett, Jonathan; Somekh-Baruch, Anelia; Martinez, Alfonso; Guillén i Fàbregas, Albert (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    This paper studies the mismatched decoding problem for binary-input discrete memoryless channels. An example is provided for which an achievable rate based on superposition coding exceeds the Csiszár-Körner-Hui rate, thus ...
  • Pasarella Sánchez, Ana Edelmira; Lobo, Jorge (ACM Association for Computer Machinery, 2017)
    Relationships like friendship to limit access to resources have been part of social network applications since their beginnings. Describing access control policies in terms of relationships is not particular to social ...
  • Ghimpeteanu, Gabriela; Batard, Thomas; Bertalmío, Marcelo; Levine, Stacey (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    In this paper, we consider an image decomposition model that provides a novel framework for image denoising. The model computes the components of the image to be processed in a moving frame that encodes its local geometry ...
  • Oramas, Sergio; Nieto Caballero, Oriol; Sordo, Mohamed; Serra, Xavier (ACM Association for Computer Machinery, 2017)
    An increasing amount of digital music is being published daily. Music streaming services often ingest all available music, but this poses a challenge: how to recommend new artists for which prior knowledge is scarce? In ...
  • Štajner , Sanja; Béchara, Hannah; Saggion, Horacio (ACL (Association for Computational Linguistics), 2015)
    In the last few years, there has been a growing number of studies addressing the Text Simplification (TS) task as a monolingual machine translation (MT) problem which translates from ‘original’ to ‘simple’ language. ...
  • Mille, Simon; Wanner, Leo (ACL (Association for Computational Linguistics), 2017)
    This demo paper presents the multilingual deep sentence generator developed by the TALN group at Universitat Pompeu Fabra, implemented as a series of rule-based graphtransducers.
  • Tauste Campo, Adrià; Vazquez-Vilar, Gonzalo; Guillén i Fàbregas, Albert; Koch, Tobias; Martinez, Alfonso (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    This paper studies the random-coding exponent of joint source-channel coding for a scheme where source messages are assigned to disjoint subsets (referred to as classes), and codewords are independently generated according ...
  • Srinivasamurthy, Ajay; Holzapfel, Andre; Cemgil, Ali Taylan; Serra, Xavier (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Most musical phenomena involve repetitive structures that enable listeners to track meter, i.e. the tactus or beat, the longer over-arching measure or bar, and possibly other related layers. Meters with long measure duration, ...
  • Ramírez, Rafael,1966-; Hazan, Amaury; Maestre Gómez, Esteban; Serra, Xavier (MIT Press, 2008)
    We describe an evolutionary approach to inducing a generative model of expressive music performance for Jazz saxophone. We begin with a collection of audio recordings of real Jazz saxophone performances from which we extract ...
  • Steck, Kathrin; Veit, Daniel; Grandy, Ronald; Bermúdez i Badia, S.; Mathews, Zenon; Verschure, Paul F. M. J.; Hansson, B. S. (Bill S.), 1959-; Knaden, Markus (Nature Publishing Group, 2012)
    How can odor-guided behavior of numerous individual Drosophila be assessed automatically with high temporal resolution? For this purpose we introduce the automatic integrated tracking and odor-delivery system Flywalk. In ...
  • Mavropoulos, Thanassis; Liparas, Dimitris; Symeonidis, Spyridon; Vrochidis, Stefanos; Kompatsiaris, Ioannis (Springer, 2017)
    The automatic extraction of relations between medical entities found in related texts is considered to be a very important task, due to the multitude of applications that it can support, from question answering systems to ...
  • Gialampoukidis, Ilias; Vrochidis, Stefanos; Kompatsiaris, Ioannis; Wanner, Leo (Springer, 2016)
    Nowadays there is an important need by journalists and media monitoring companies to cluster news in large amounts of web articles, in order to ensure fast access to their topics or events of interest. Our aim in this work ...
  • Gialampoukidis, Ilias; Moumtzidou, Anastasia; Liparas, Dimitris; Vrochidis, Stefanos; Kompatsiaris, Ioannis (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Nowadays, multimedia retrieval has become a task of high importance, due to the need for efficient and fast access to very large and heterogeneous multimedia collections. An interesting challenge within the aforementioned ...
  • Bellur, Ashwin; Ishwar, Vignesh; Serra, Xavier; Murthy, Hema A. (Universitat Pompeu Fabra, 2012)
    In this paper, we describe several techniques for detecting tonic pitch value in Indian classical music. In Indian music, the raga is the basic melodic framework and it is built on the tonic. Tonic detection is therefore ...
  • Serra, Xavier; Koduri, Gopala Krishna (2013)
    Knowledge representation technologies developed in the semantic web context can be utilized to bridge the gap between music information research and disciplines like musicology and music theory. This will greatly enhance ...
  • Rauschenberger, Maria; Rello, Luz; Füchsel, Silke; Thomaschewski, Jörg (ELRA (European Language Resources Association), 2016)
    In this paper we present a language resource for German, composed of a list of 1,021 unique errors extracted from a collection of texts written by people with dyslexia. The errors were annotated with a set of linguistic ...
  • Costa-jussà, Marta R.; Fonollosa, José A Rodriguez; Mariño Acebal, José B.; Poch, Marc; Farrús, Mireia (Institute of Informatics Slovak Academy of Sciences, 2014)
    We present a large Spanish-Catalan parallel corpus extracted from ten years of the paper edition of a bilingual Catalan newspaper. The produced corpus of 7:5M parallel sentences (around 180M words per language) is useful ...
