  • Spectral learning of transducers over continuous sequences 

    Recasens, Adria; Quattoni, Ariadna Julieta (2013-01-01)
    External research report
    Open Access
    In this paper we present a spectral algorithm for learning weighted nite state transducers (WFSTs) over paired input-output sequences, where the input is continuous and the output discrete. WFSTs are an important tool for ...
  • Frequent sets, sequences and taxonomies: new efficient algorithmic proposals 

    Baixeries i Juvillà, Jaume; Casas Garriga, Gemma; Balcázar Navarro, José Luis (2000)
    External research report
    Open Access
    We describe efficient algorithmic proposals to approach three fundamental problems in data mining: association rules, episodes in sequences, and generalized association rules over hierarchical taxonomies. The association ...
  • An integer linear programming representation for data-center power-aware management 

    Berral García, Josep Lluís; Gavaldà Mestre, Ricard; Torres Viñals, Jordi (2010-11-12)
    External research report
    Open Access
    This work exposes how to represent a grid data-center based scheduling problem, taking the advantages of the virtualization and consolidation techniques, as a linear integer programming problem including all three mentioned ...
