  • On methods to assess the significance of community structure in networks of financial time series 

    Arratia Quesada, Argimiro Alejandro; Renedo Mirambell, Martí (2017)
    Conference lecture
    Open Access
    We consider the problem of determining whether the community structure found by a clustering algorithm applied to nancial time series is statistically signi cant, or is due to pure chance, when no other information ...

    This paper introduces a forecasting procedure based on mul-tivariate dynamic kernels to re-examine –under a non linear framework–the experimental tests reported by Welch and Goyal showing that severalvariables proposed in ...
  • Improving adaptation and interpretability of a short-term traffic forecasting system 

    Mena Yedra, Rafael; Casas Vilaró, Jordi; Djukic, Tamara; Gavaldà Mestre, Ricard (2017)
    Conference report
    Open Access
    Traffic management is being more important than ever, especially in overcrowded big cities with over-pollution problems and with new unprecedented mobility changes. In this scenario, road-traffic prediction plays a key ...
  • Web apps and imprecise probabilities 

    Castro Rabal, Jorge; Gabarró Vallès, Joaquim; Serna Iglesias, María José (Springer, 2018)
    Conference report
    Open Access
    We propose a model for the behaviour of Web apps in the unreliable WWW. Web apps are described by orchestrations. An orchestration mimics the personal use of the Web by defining the way in which Web services are invoked. ...
  • Power to invest 

    Castro Rabal, Jorge; Gabarró Vallès, Joaquim; Serna Iglesias, María José (2018)
    Conference report
    Open Access
    In this post recession time it is important to measure the possibilities offered by a society in relation to investments. To do that, we consider an investment schema I= (R;R_1,...,R_n) where R is a lower bound on the ...
  • New ensemble methods for evolving data streams 

    Bifet Figuerol, Albert Carles; Holmes, Geoffrey; Pfahringer, Bernhard; Kirkby, R; Gavaldà Mestre, Ricard (Association for Computing Machinery (ACM), 2009)
    Conference report

    Advanced analysis of data streams is quickly becoming a key area of data mining research as the number of applications demanding such processing increases. Online mining when such data streams evolve over time, that is ...
  • Characterizing covers of functional dependencies using FCA 

    Codocedo, Victor; Baixeries i Juvillà, Jaume; Kaytoue, Mehdi; Napoli, Amedeo (2018)
    Conference report
    Open Access
    Functional dependencies (FDs) can be used for various important operations on data, for instance, checking the consistency and the quality of a database (including databases that contain complex data). Consequently, a ...
  • Ordocoordinación: cómo organizar 700 estudiantes en un nuevo campus (y no morir en el intento) 

    Castro Rabal, Jorge; Farreres de la Morena, Xavier; Gabarró Vallès, Joaquim; Nivela Alós, M. Pilar Brígida; Pérez Poch, Antoni; Pino Blanco, Elvira; Rivero Almeida, José Miguel (Asociación de Enseñantes Universitarios de la Informática (AENUI), 2018)
    Conference report
    Open Access
    Since Autumn Term 2017 the Department of Computer Science of the Universitat Politecnica de Catalunya UPC-BarcelonaTech is in charge of teaching ”Fundamentals of Programming” in the new DiagonalBeso ´s Campus, at EEBE ...
  • Emergence of linguistic laws in human voice 

    González Torre, Iván; Luque Serrano, Bartolo; Lacasa, Lucas; Miramontes, Octavio; Hernández Fernández, Antonio (2017)
    Conference lecture
    Open Access
    Linguistic laws constitute one of the quantitative cornerstones of modern cognitive sciences and have been routinely investigated in written corpora, or in the equivalent transcription of oral corpora. This means that ...
  • Logspace self-reducibility 

    Balcázar Navarro, José Luis (Institute of Electrical and Electronics Engineers (IEEE), 1988)
    Conference report
    Open Access
    A definition of self-reducibility is proposed to deal with logarithmic space complexity classes. A general property derived from the definition is used to prove known results comparing uniform and nonuniform complexity ...
  • Count-invariance including exponentials 

    Kuznetsov, Stepan; Morrill, Glyn; Valentín, Oriol (Association for Computational Linguistics, 2017)
    Conference lecture
    Restricted access - publisher's policy
    We define infinitary count-invariance for categorial logic, extending countinvariance for multiplicatives (van Benthem, 1991) and additives and bracket modalities (Valentín et al., 2013) to include exponentials. This ...
