Recent Submissions

  • Gómez Cañón, Juan Sebastián; Cano, Estefanía; Herrera Boyer, Perfecto, 1964-; Gómez Gutiérrez, Emilia, 1975- (Institute of Electrical and Electronics Engineers (IEEE), 2021)
    In this study, we address emotion recognition using unsupervised feature learning from speech data, and test its transferability to music. Our approach is to pre-train models using speech in English and Mandarin, and then ...
  • Palomares, Roberto P.; Haro Ortega, Gloria; Ballester, Coloma (Springer, 2014)
    This paper proposes a new regularization term for optical flow related problems. The proposed regularizer properly handles rotation movements and it also produces good smoothness conditions on the flow field while preserving ...
  • Rezaeirowshan, Babak; Ballester, Coloma; Haro Ortega, Gloria (Springer, 2016)
    Estimating 3D structure of the scene from a single image remains a challenging problem in computer vision. This paper proposes a novel approach to obtain a global depth order of objects by incorporating monocular perceptual ...
  • Gómez Cañón, Juan Sebastián; Herrera Boyer, Perfecto, 1964-; Gómez Gutiérrez, Emilia, 1975-; Cano, Estefanía (2019)
    In the present study, we address the relationship between the emotions perceived in pop and rock music (mainly in Euro-American styles with English lyrics) and the language spoken by the listener. Our goal is to ...
  • Blaauw, Merlijn; Bonada, Jordi, 1973-; Daido, Ryunosuke (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    There are many use cases in singing synthesis where creating voices from small amounts of data is desirable. In text-to-speech there have been several promising results that apply voice cloning techniques to modern deep ...
  • Blanco, Angel David; Ramírez, Rafael,1966- (ACM Association for Computer Machinery, 2017)
    We present a study of the effects of feedback technologies on the learning process of novice violin students. Twenty-one subjects participated in our experiment, divided into two groups: Beginners (participants with no ...
  • Schaper, Marie-Monique; Malinverni, Laura; Parés, Narcís, 1966- (ACM Association for Computer Machinery, 2014)
    The paper presents an exploratory study aimed toward including children in the design of an Interactive Learning Environment based on Full-Body Interaction. The study proposes a method based on using Participatory Design ...
  • Yesiler, Furkan; Serrà Julià, Joan; Gómez Gutiérrez, Emilia, 1975- (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    The version identification (VI) task deals with the automatic detection of recordings that correspond to the same underlying musical piece. Despite many efforts, VI is still an open problem, with much room for improvement, ...
  • Ramires, António; Chandna, Pritish; Favory, Xavier; Gómez Gutiérrez, Emilia, 1975-; Serra, Xavier (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    We present a deep neural network-based methodology for synthesising percussive sounds with control over high-level timbral characteristics of the sounds. This approach allows for intuitive control of a synthesizer, enabling ...
  • Blaauw, Merlijn; Bonada, Jordi, 1973- (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    We propose a sequence-to-sequence singing synthesizer, which avoids the need for training data with pre-aligned phonetic and acoustic features. Rather than the more common approach of a content-based attention mechanism ...
  • Chandna, Pritish; Blaauw, Merlijn; Bonada, Jordi, 1973-; Gómez Gutiérrez, Emilia, 1975- (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    We present a deep learning based methodology for extracting the singing voice signal from a musical mixture based on the underlying linguistic content. Our model follows an encoder-decoder architecture and takes as input ...
  • Alonso-Jiménez, Pablo; Bogdanov, Dmitry; Pons Puig, Jordi; Serra, Xavier (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Essentia is a reference open-source C ++ /Python library for audio and music analysis. In this work, we present a set of algorithms that employ TensorFlow in Essentia, allow predictions with pre-trained deep learning models, ...
  • Wanner, Leo; Domínguez Bajo, Mónica; Soler Company, Juan (ACL (Association for Computational Linguistics), 2020)
    This paper introduces ThemePro, a toolkit for the automatic analysis of thematic progression. Thematic progression is relevant to natural language processing (NLP) applications dealing, among others, with discourse structure, ...
  • Ferraro, Andrés; Jannach, Dietmar; Serra, Xavier (ACM Association for Computer Machinery, 2020)
    Session-based recommendation is a problem setting where the task of a recommender system is to make suitable item suggestions based only on a few observed user interactions in an ongoing session. The lack of long-term ...
  • Dzhambazov, Georgi Bogomilov; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2016)
  • Fisas Elizalde, Beatriz; Espinosa-Anke, Luis; Codina Filbà, Joan; Wanner, Leo (ACL (Association for Computational Linguistics), 2020)
    Collocations in the sense of idiosyncratic lexical co-occurrences of two syntactically bound words traditionally pose a challenge to language learners and many Natural Language Processing (NLP) applications alike. Reliable ...
  • Pérez Sanagustín, Maria del Mar; Melero Merino, Javier; Hernández Leo, Davinia; Delgado Kloos, Carlos; Blat, Josep (Springer, 2013)
    EtiquetAR is a web-authoring application designed towards learning purposes to support practitioners in the design of activities based on QR codes. This poster illustrates how etiquetAR QR codes were used to augment a ...
  • De la Fuente Valentín, Luis; Pérez Sanagustín, Maria del Mar; Santos Rodríguez, Patrícia; Hernández Leo, Davinia; Pardo, Abelardo; Delgado Kloos, Carlos; Blat, Josep (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    The introduction of portable devices in education opens up new possibilities for Computer Supported Collaborative Learning by providing advanced learning scenarios with activities in different spatial locations. However, ...
  • Baeza Yates, Ricardo; Gabarró Vallès, Joaquim; Messeguer, Xavier (Springer, 1998)
    We are interested in the fringe analysis of synchronized parallel insertion algorithms on 2–3 trees, namely the algorithm of W. Paul, U. Vishkin and H. Wagener (PVW). This algorithm inserts keys into a tree of size n with ...
  • Ma, Jiefei; Rankothge, Windhya; Makaya, Christian; Morales, Mariceli; Le, Franck; Lobo, Jorge (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    We present an architectural design and a reference implementation for horizontal scaling of virtual network function chains. Our solution does not require any changes to network functions and is able to handle stateful ...
