  • Zehlike, Meike; Bonchi, Francesco; Castillo, Carlos; Hajian, Sara; Megahed, Mohamed; Baeza-Yates, Ricardo (ACM Association for Computer Machinery, 2017)
    In this work, we define and solve the Fair Top-k Ranking problem, in which we want to determine a subset of k candidates from a large pool of n>>k candidates, maximizing utility (i.e., select the “best” candidates) subject ...
  • Purohit, Hemant; Castillo, Carlos; Imran, Muhammad; Pandey, Rahul (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    xtensive research on social media usage during emergencies has shown its value to provide life-saving information, if a mechanism is in place to filter and prioritize messages. Existing ranking systems can provide a ...
  • Favory, Xavier; Fonseca, Eduardo; Font, Frederic; Serra, Xavier (FRUCT, 2018)
    Properly annotated multimedia content is crucial for supporting advances in many Information Retrieval applications. It enables, for instance, the development of automatic tools for the annotation of large and diverse ...
  • Fonseca, Eduardo; Plakal, Manoj; Font, Frederic; Ellis, Daniel P. W.; Favory, Xavier; Pons, Jordi; Serra, Xavier (Tampere University of Technology, 2018)
    This paper describes Task 2 of the DCASE 2018 Challenge, titled “General-purpose audio tagging of Freesound content with AudioSet labels”. This task was hosted on the Kaggle platform as “Freesound General-Purpose Audio ...
  • Serrà, Joan; Surís, Dídac; Miron, Marius; Karatzoglou, Alexandros (Proceedings of Machine Learning Research, 2018)
    Catastrophic forgetting occurs when a neural network loses the information learned in a previous task after training on subsequent tasks. This problem remains a hurdle for artificial intelligence systems with sequential ...
  • Giraldo, Sergio; Ortega, Ariadna; Perez, Alfonso; Ramírez, Rafael; Waddell, George; Williamon, Aaron (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    The automatic assessment of music performance has become an area of special interest due to the increasing amount of technology-enhanced music learning systems. However, in most of these systems the assessment of the musical ...
  • Fonseca, Eduardo; Gong, Rong; Serra, Xavier (Cyprus University of Technology, 2018)
    In the past, Acoustic Scene Classification systems havebeen based on hand crafting audio features that are input toa classifier. Nowadays, the common trend is to adopt datadriven techniques, e.g., deep learning, where audio ...
  • Yesiler, Furkan; Bozkurt, Baris; Serra, Xavier (Cyprus University of Technology, 2018)
    This work focuses on automatic makam recognition taskfor Turkish makam music (TMM) using pitch distributionsthat are widely used in mode recognition tasks for variousmusic traditions. Here, we aim to improve the performanceof ...
  • Ramíırez-Cifuentes, Diana; Mayans Yern, Marc; Freire, Ana (Springer, 2018)
    This paper proposes an approach for the early detection of anorexia nervosa (AN) on social media. We present a machine learning approach that processes the texts written by social media users. This method relies on a set ...
  • Sanromà, Gerard; Andrea, Víctor; Benkarim, Oualid M.; Manjón, José V.; Coupé, Pierrick; Camara, Oscar; Piella Fenoy, Gemma; González Ballester, Miguel Ángel, 1973- (Springer, 2017)
    Alzheimer’s disease (AD) is characterized by a progressive decline in the cognitive functions accompanied by an atrophic process which can already be observed in the early stages using magnetic resonance images (MRI). ...
  • Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2018)
    In this paper we present a new dataset of time-aligned jazz harmony transcriptions. This dataset is a useful resource for content-based analysis, especially for training and evaluating chord transcription algorithms. Most ...
  • Demirel, Emir; Bozkurt, Baris; Serra, Xavier (2018)
    This work focuses on the automatic makam recognition task for Turkish Makam Music using chroma features. Chroma features are widely used for music identification and tonal recognition tasks such as key estimation or chord ...
  • Chamorro Servent, Judit; Aguirre, Juan; Ripoll, Jorge; Vaquero, Juan J.; Deseo, Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    Fluorescence Enhanced Diffuse Optical Tomography (FDOT) retrieves 3D distributions of fluorophore concentration in small animals, non-invasively and in vivo. The FDOT problem can be formulated as a system of equations, ...
  • Albó Pérez, Laia; Hernández Leo, Davinia; Oliver Riera, Miquel (CEUR Workshop Proceedings, 2015)
    Blended Massive Open Online Courses (bMOOCs) have arisen as a blended learning strategy that combines the use of MOOC platform-supported activities and video-based content with in-class face-to-face activities in ...
  • Herrera Boyer, Perfecto; Serra, Xavier; Peeters, Geoffroy (1999)
    Sound content description is one of the aims of the MPEG-7 initiative. Although MPEG-7 focuses on indexing and retrieval of audio, there are other sound content-based processing applications waiting to be developed once ...
  • Sordo, Mohamed; Oramas, Sergio; Espinosa-Anke, Luis (Springer, 2015)
    This paper presents a method for the generation of struc- tured data sources for music recommendation using information extracted from unstructured text sources. The proposed method identi es entities in text that are ...
  • Ivorra Cano, Antoni, 1974-; Becerra-Fajardo, Laura; Tudela-Pi, Marc; Ivorra Cano, Antoni, 1974- (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Galvanic coupling, or more precisely, volume conduction, can be used to communicate with and to transfer power to electronic implants. Since no bulky components for power, such as coils or batteries, are required within ...
  • Rauschenberger, Maria (ACM Association for Computer Machinery, 2016)
    The aim of this research is to show that a playful approach combined with music can detect children with dyslexia. Early detection will prevent children from suffering in school until they are detected due to bad grades. ...
  • Ezeoke, Maurice; Borda Fortuny, Cristina; Tong, Kenneth (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    A barefaced terrain scattering model for oil sand exploration will enable the discrimination of different terrain types using incoherent polarimetric decomposition. We use computer electromagnetic modeling with finite ...
