    Theoretical studies on the information structure–prosody interface argue that the content packaged in terms of theme and rheme correlates with the intonation of the corresponding sentence as regards to rising and falling ...
  • Pons Puig, Jordi; Slizovskaia, Olga; Gómez Gutiérrez, Emilia, 1975-; Serra, Xavier (European Association for Signal Processing (EURASIP), 2017)
    The focus of this work is to study how to efficiently tailor Convolutional Neural Networks (CNNs) towards learning timbre representations from log-mel magnitude spectrograms. We first review the trends when designing ...
  • Gulati, Sankalp; Serrà Julià, Joan; Ganguli, Kaustuv Kanti; Sentürk, Sertan; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2016)
    Raga is the melodic framework of Indian art music. It is a core concept used in composition, performance, organization, and pedagogy. Automatic raga recognition is thus a fundamental information retrieval task in Indian ...
  • Marchini, Marco, 1984-; Papiotis, Panagiotis, 1985-; Maestre Gómez, Esteban (University of London, 2012)
    This work presents a preliminary study of timing synchronization/nphenomena in string quartet performance. Accurate timing information/nextracted from real recordings is used to compare timing deviations/nin solo and ...
  • Aragón, Pablo; Gómez, Vicenç; Kaltenbrunner, Andreas (Association for the Advancement of Artificial Intelligence (AAAI), 2017)
    Online discussion is essential for the communication and collaboration of online communities. The reciprocal exchange of messages between users that characterizes online discussion can be represented in many different ...
  • Gialampoukidis, Ilias; Vrochidis, Stefanos; Kompatsiaris, Ioannis; Antoniou, Ioannis (2017)
    Topic detection is usually considered as a decision process implemented in some relevant context, for example clustering. In this case, clusters correspond to topics that should be identifed. Density-based clustering, ...
  • Dalmau, Víctor; Krokhin, Andrei; Manokaran, Rajsekar (SIAM (Society for Industrial and Applied Mathematics), 2015)
    We study the approximability of Minimum Constraint Satisfaction Problems (Min CSPs) with a fixed finite constraint language Γ on an arbitrary finite domain. The goal in such a problem is to minimize the number of unsatisfied ...
  • Wanner, Leo; Blat, Josep; Dasiopoulou, Stamatia; Domínguez Bajo, Mónica; Llorach, Gerard; Mille, Simon; Sukno, Federico Mateo; Kamateri, Eleni; Kompatsiaris, Ioannis; Vrochidis, Stefanos; André, Elisabeth; Lingenfelser, Florian; Mehlmann, Gregor; Stam, Andries; Stellingwerff, Ludo; Lamel, Lori; Vieru, Bianca; Minker, Wolfgang; Pragst, Louisa; Ultes, Stefan (ACM Association for Computer Machinery, 2016)
    We present work in progress on an intelligent embodied conversation agent in the basic care and healthcare domain. In contrast to most of the existing agents, the presented agent is aimed to have linguistic cultural, social ...
  • Serra, Xavier (International Computer Music Conference, 2005)
    In this article I give a personal view on what could be a roadmap for the research in Music Technology. I will describe the context of this research, the current state of the art, the challenges that lie ahead and I will ...
  • Becerra-Fajardo, Laura; Ivorra Cano, Antoni, 1974- (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Electrical stimulation has been explored to restore/nthe capabilities of the nervous system in paralysis patients. This/narea of research and of clinical practice, known as Functional/nElectrical Stimulation, would greatly ...
  • Sentürk, Sertan; Gulati, Sankalp; Serra, Xavier (Computer Engineering Department, Bogaziçi University, 2014)
    Audio-score alignment is a multi-modal task, which facilitates many related tasks such as intonation analysis, structure analysis and automatic accompaniment. In this paper, we present a audio-score alignment methodology ...
  • Rach, Niklas; Minker, Wolfgang; Wanner, Leo (CEUR Workshop Proceedings, 2017)
    In this work we propose a scheme for an Argumentative Dialogue System that allows a user to discuss a certain topic with a virtual agent using natural language. Starting from an agent vs agent case, we address the ...
  • Meditskos, Georgios; Dasiopoulou, Stamatia; Pragst, Louisa; Ultes, Stefan; Vrochidis, Stefanos; Wanner, Leo (ACM Association for Computer Machinery, 2016)
    In this paper, we describe the principles and technologies that underpin the development of an adaptive dialogue manager framework, tailored to carrying out human-agent conversations in a natural, robust and exible ...
  • Domínguez Bajo, Mónica; Farrús, Mireia; Burga Díaz, Alicia; Wanner, Leo (ISCA, 2014)
    This paper deals with the adaptation of AuToBI annotation for speech synthesis purposes. AuToBI is a tool that automatically determines and classifies the standard ToBI labels for American English. AuToBI annotation is ...
  • Amarasinghe, Ishari; Hernández Leo, Davinia; Jonsson, Anders, 1973- (2017)
