  • 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 ...
  • Rodríguez, Sonia; Gómez Gutiérrez, Emilia, 1975-; Cuesta i Mussarra, Helena (Folk Music Analysis, 2018)
    This work deals with the automatic transcription and characterization of flamenco guitar, with a focus on short melodic interludes improvised between sung verses. These are called falsetas in the flamenco argot and are ...
  • Bonet, Blai; Geffner, Héctor (Association for the Advancement of Artificial Intelligence (AAAI), 2012)
    It has been shown recently that the complexity of belief tracking in deterministic conformant and contingent planning is exponential in a width parameter that is often bounded and small. In this work, we introduce a new ...
  • Bonet, Blai; Geffner, Héctor (Association for the Advancement of Artificial Intelligence (AAAI), 2012)
    In the presence of non-admissible heuristics, A* and other best-first algorithms can be converted into anytime optimal algorithms over OR graphs, by simply continuing the search after the first solution is found. The ...
  • Gómez Gutiérrez, Emilia, 1975-; Guerrero, Alba; Rodríguez, Sonia (2018)
    Cante Flamenco Tech es un proyecto pedagógico cuyo objetivo es el de generar materiales docentes online para el aprendizaje del cante flamenco, siguiendo un énfasis tecnolégico. Para ello, el proyecto integra las tecnologías ...
  • Cuesta i Mussarra, Helena; Gómez Gutiérrez, Emilia, 1975-; Martorell Domínguez, Agustín; Loáiciga, Felipe (2018)
    Choir singers synchronize their fundamental frequency (f0) and timing when they perform together. In this work, we investigate several expressive characteristics of choir singing, with special emphasis on unison ...
  • Slizovskaia, Olga; Gómez Gutiérrez, Emilia, 1975-; Haro Ortega, Gloria (ACM Association for Computer Machinery, 2017)
    This paper presents a method for recognizing musical instruments in user-generated videos. Musical instrument recognition from music signals is a well-known task in the music information retrieval (MIR) field, where current ...
  • Blaauw, Merlijn; Bonada, Jordi, 1973- (International Speech Communication Association (ISCA), 2017)
    We present a new model for singing synthesis based on a modified version of the WaveNet architecture. Instead of modeling raw waveform, we model features produced by a parametric vocoder that separates the influence of ...
  • Baumgartner, Laura; González Ballester, Miguel Ángel, 1973-; Noailly, Jérôme (International Research Council on Biomechanics of Injury (IRCOBI), 2018)
    The causes of intervertebral disc (IVD) ruptures continue to elude both biomechanists and clinicians. It is widely accepted that unique traumatic high‐load impacts are unlikely to lead to isolated IVD herniation. Therefore, ...
  • Schmitt, Kai‐Uwe; Baumgartner, Laura; Muser, Markus; Furter, Kerstin; Scholz, Stefan; Lüber, Barbara; Thomas, Pete; Simma, Anja (International Research Council on Biomechanics of Injury (IRCOBI), 2014)
    National accident statistics in European countries as well as in many other countries are based on data recorded by the police. Generally, such data also include police reported estimates of the injury severity of accident ...
  • Barbieri, Francesco; Espinosa-Anke, Luis; Camacho-Collados, Jose; Schockaert, Steven; Saggion, Horacio (ACL (Association for Computational Linguistics), 2018)
    Human language has evolved towards newer forms of communication such as social media, where emojis (i.e., ideograms bearing a visual meaning) play a key role. While there is an increasing body of work aimed at ...
  • Domínguez Bajo, Mónica; Burga Díaz, Alicia; Farrús, Mireia; Wanner, Leo (2018)
    Conversational technologies that assist elderly people need to adapt to common disabilities in old age. Visual, hearing and even more so cognitive impairments pose serious difficulties for our seniors to handle a standard ...

    Conversational technologies that assist elderly people need to adapt to common disabilities in old age. Visual, hearing and even more so cognitive impairments pose serious difficulties for our seniors to handle a standard ...
  • Karakurt, Altug; Sentürk, Sertan; Serra, Xavier (ACM Association for Computer Machinery, 2016)
    In the general sense, mode defines the melodic framework and tonic acts as the reference tuning pitch for the melody in the performances of many music cultures. The mode and tonic information of the audio recordings is ...
  • Haro Ortega, Gloria (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    We propose a 3D reconstruction algorithm based on silhouettes and color images. It is robust to inconsistent silhouettes, often common in real applications due to occlusions, errors in the background subtraction, noise or ...
  • Rezaeirowshan, Babak; Ballester, Coloma; Haro Ortega, Gloria (SCITEPRESS – Science and Technology Publications, Lda., 2016)
    In this paper we propose a method to estimate a global depth order between the objects of a scene using information from a single image coming from an uncalibrated camera. The method we present stems from early vision cues ...
  • Palomares, Roberto P.; Haro Ortega, Gloria; Ballester, Coloma (SCITEPRESS – Science and Technology Publications, Lda., 2017)
    This paper presents a novel variational approach for the joint estimation of scene flow and occlusions. Our method does not assume that a depth sensor is available. Instead, we use a stereo sequence and exploit the fact ...
  • Oliver, Maria; Palomares, Roberto P.; Ballester, Coloma; Haro Ortega, Gloria (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    We propose a new variational method for the completion of moving shapes through binary video inpainting that works by smoothly recovering the objects into an inpainting hole. We solve it by a simple dynamic shape analysis ...
  • Oliver, Maria; Raad, Lara; Ballester, Coloma; Haro Ortega, Gloria (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    This work presents an automatic method for optical flow inpainting. Given a video, each frame domain is endowed with a Riemannian metric based on the video pixel values. The missing optical flow is recovered by solving the ...
  • Oliver, Maria; Haro Ortega, Gloria; Fedorov, Vadim; Ballester, Coloma (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    This paper proposes a novel patch-based variational segmentation method that considers adaptive patches to characterize, in an affine invariant way, the local structure of each homogeneous texture region of the image and ...
