  • Morales-Jiménez, David; Lopez-Martínez, F. Javier; Martos-Naya, Eduardo; Paris, José F.; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    This paper presents a new connection between the generalized Marcum-Q function and the confluent hypergeometric function of two variables, Φ3. This result is then applied to the closed-form characterization of the bivariate ...
  • Atasoy, Selen; Roseman, Leor; Kaelen, Mendel; Kringelbach, Morten L.; Deco, Gustavo; Carhart-Harris, Robin L. (Nature Research, 2017)
    Recent studies have started to elucidate the effects of lysergic acid diethylamide (LSD) on the human brain but the underlying dynamics are not yet fully understood. Here we used ’connectome-harmonic decomposition’, a novel ...
  • Vazquez-Corral, Javier; Zamir, Syed Waqas; Bertalmío, Marcelo (S. Hirzel Verlag (SHV), 2014)
    Gamut reduction transforms the colors of an input image within the range of a target device. A good gamut reduction algorithm will preserve the experience felt by the viewer of the original image. Saliency algorithms ...
  • Toro Soto, Juan Manuel, 1976-; Crespo Bojorque, Paola, 1985- (The Comparative Cognition Society, 2017)
    Consonance is a major feature in harmonic music that has been related to how pleasant a sound is perceived. Consonant chords are defined by simple frequency ratios between their composing tones, whereas dissonant chords ...
  • Jonsson, Anders, 1973-; Lotinac, Damir (IOS Press, 2016)
    Hierarchical Task Networks (HTNs) are a common model for encoding knowledge about planning domains in the form of task decompositions. We present a novel algorithm that uses invariant analysis to construct an HTN from the ...
  • Gouyon, Fabien; Herrera Boyer, Perfecto; Gómez Gutiérrez, Emilia, 1975-; Cano, Pedro; Bonada, Jordi, 1973-; Loscos, Àlex; Amatriain, Xavier; Serra, Xavier (Logos Verlag, 2008)
    In this chapter, we provide an overview of state-of-the-art algorithms for the automatic description of music audio signals, both from a low-level perspective (focusing on signal characteristics) and a more musical perspective ...
  • Cano, Pedro; Koppenberger, Markus; Wack, Nicolas (ACM Association for Computer Machinery, 2005)
    We present the MusicSurfer, a metadata free system for the interaction with massive collections of music. MusicSurfer automatically extracts descriptions related to instrumentation, rhythm and harmony from music audio ...
  • Ruzzene, Giulia; Omelchenko, Iryna; Schöll, Eckehard; Zakharova, Anna; Andrzejak, Ralph Gregor (American Institute of Physics (AIP), 2019)
    We propose a method to control chimera states in a ring-shaped network of nonlocally coupled phase oscillators. This method acts exclusivelyon the network’s connectivity. Using the idea of a pacemaker oscillator, we ...
  • Santamaría, Guillermo; Gómez, Vicenç (2015)
    In contrast to traditional social networks, signed ones encode both relations of affinity and disagreement. Community discovery in this kind of networks has been successfully addressed using the Potts model, originated ...
  • Srinivasamurthy, Ajay; Koduri, Gopala Krishna; Gulati, Sankalp; Ishwar, Vignesh; Serra, Xavier (Michigan Publishing, 2014)
    Research corpora are representative collections of data and are essential to develop data-driven approaches in Music Information Research (MIR). We address the problem of building research corpora for MIR in Indian art ...
  • Pérez Almendros, Carla; Espinosa-Anke, Luis; Torres Valdés, Rosa (Elsevier, 2013)
    We present a corpus-based study of the Corporate Social Responsibility Reports issued by companies who operate in the Spanish Stock Market IBEX 35. Natural Language Processing methods are used for extracting informative ...
  • Stajner, Sanja; Drndarevic, Biljana; Saggion, Horacio (Centro de Investigación en Computación, 2013)
    This study addresses the automatic simplification of texts in Spanish in order to make them more accessible to people with cognitive disabilities. A corpus analysis of original and manually simplified news articles was ...
  • Slizovskaia, Olga; Gómez Gutiérrez, Emilia, 1975-; Haro Ortega, Gloria (International Society for Music Information Retrieval (ISMIR), 2017)
    This work aims at investigating cross-modal connections between audio and video sources in the task of musical instrument recognition. We also address in this work the understanding of the representations learned by ...
  • Benkarim, Oualid M.; Hahner, Nadine; Piella Fenoy, Gemma; Gratacós Solsona, Eduard; González Ballester, Miguel Ángel, 1973-; Eixarch, Elisenda; Sanromà, Gerard (Elsevier, 2018)
    Neuroimaging of brain diseases plays a crucial role in understanding brain abnormalities and early diagnosis. Of great importance is the study of brain abnormalities in utero and the assessment of deviations in case of ...
  • Theodoni, Panagiota; Panagiotaropoulos, Theofanis I.; Kapoor, Vishal; Logothetis, N.; Deco, Gustavo (Frontiers Media, 2011)
    Perceptual bistability arises when two conflicting interpretations of an ambiguous stimulus or images in binocular rivalry (BR) compete for perceptual dominance. From a computational point of view, competition models based ...
  • Senden, Mario; Reuter, Niels; Heuvel, Martijn van den; Goebel, Rainer; Deco, Gustavo (Elsevier, 2017)
    Cognition is hypothesized to require the globally coordinated, functionally relevant integration of otherwise segregated information processing carried out by specialized brain regions. Studies of the macroscopic connectome ...
  • Roland, Per E.; Hilgetag, Claus C.; Deco, Gustavo (Frontiers Media, 2014)
    In principle, cortico-cortical communication dynamics is simple: neurons in one cortical area communicate by sending action potentials that release glutamate and excite their target neurons in other cortical areas. In ...
  • Rubio Ballester, Belén; Maier, Martina; San Segundo Mozo, Rosa María; Castañeda, Victoria; Duff, Armin; Verschure, Paul F. M. J. (BioMed Central, 2016)
    Background: After stroke, patients who suffer from hemiparesis tend to suppress the use of the affected extremity, a condition called learned non-use. Consequently, the lack of training may lead to the progressive deterioration ...
  • Ceresa, Mario; Olivares Miyares, Andy Luis; Noailly, Jérôme; González Ballester, Miguel Ángel, 1973- (Frontiers, 2018)
    Chronic Obstructive Pulmonary Disease (COPD) is a disabling respiratory pathology, with a high prevalence and a significant economic and social cost. It is characterized by different clinical phenotypes with different risk ...
  • Andrzejak, Ralph Gregor; Laiou, Petroula (American Physical Society, 2017)
    The understanding of interacting dynamics is important for the characterization of real-world/nnetworks. In general real-world networks are heterogeneous in the sense that each node of the/nnetwork is a dynamics with di ...
