  • Construct, merge, solve and adapt versus large neighborhood search for solving the multi-dimensional Knapsack problem: Which one works better when? 

    Lizárraga Olivas, Evelia; Blesa Aguilera, Maria Josep; Blum, Christian (Springer, 2017)
    Conference lecture
    Open Access
    Both, Construct, Merge, Solve and Adapt (CMSA) and Large Neighborhood Search (LNS), are hybrid algorithms that are based on iteratively solving sub-instances of the original problem instances, if possible, to optimality. ...
  • A hybrid evolutionary algorithm based on solution merging for the longest arc-preserving common subsequence problem 

    Blum, Christian; Blesa Aguilera, Maria Josep (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    Conference lecture
    Open Access
    The longest arc-preserving common subsequence problem is an NP-hard combinatorial optimization problem from the field of computational biology. This problem finds applications, in particular, in the comparison of art-annotated ...
  • An angel-daemon approach to assess the uncertainty in the power of a collectivity to act 

    Fragnito, Giulia; Gabarró Vallès, Joaquim; Serna Iglesias, María José (Springer, 2017)
    Conference report
    Open Access
    We propose the use of the angel-daemon framework to assess the Coleman's power of a collectivity to act under uncertainty in weighted voting games. In this framework uncertainty profiles describe the potential changes ...
  • Parsing logical grammar: CatLog3 

    Morrill, Glyn (Stockholm University, 2017)
    Conference report
    Open Access
    CatLog3 is a Prolog parser/theorem-prover for (type) logical (categorial) grammar. In such logical grammar, grammar is reduced to logic: a string of words is grammatical if and only if an associated logical statement is a ...
  • A polynomial-time algorithm for the Lambek calculus with brackets of bounded order 

    Kanovich, Max; Kuznetsov, Stepan; Morrill, Glyn; Scedrov, Andre (Dagstuhl Publishing, 2017)
    Conference report
    Open Access
    Lambek calculus is a logical foundation of categorial grammar, a linguistic paradigm of grammar as logic and parsing as deduction. Pentus (2010) gave a polynomial-time algorithm for determining provability of bounded depth ...
  • Mobile graphics 

    Agus, Marco; Gobbetti, Enrico; Marton, Fabio; Pintore, Giovanni; Vázquez Alcocer, Pere Pau (European Association for Computer Graphics (Eurographics), 2017)
    Conference lecture
    Open Access
    The increased availability and performance of mobile graphics terminals, including smartphones and tablets with high resolution screens and powerful GPUs, combined with the increased availability of high-speed mobile data ...
  • Virtual reality to teach anatomy 

    Fairén González, Marta; Farrés, Mariona; Moyes Ardiaca, Jordi; Insa, Esther (European Association for Computer Graphics (Eurographics), 2017)
    Conference report
    Open Access
    Virtual Reality (VR) and Augmented Reality (AR) have been gradually introduced in the curriculum of schools given the benefits they bring to classical education. We present an experiment designed to expose students to a ...
  • Deep learning for detecting freezing of gait episodes in Parkinson’s disease based on accelerometers 

    Camps, Julià; Samà Monsonís, Albert; Martín Muñoz, Mario; Rodríguez Martín, Daniel Manuel; Pérez López, Carlos; Alcaine, Sheila; Mestre, Berta; Prats, Anna; Crespo, M. Cruz; Cabestany Moncusí, Joan; Bayés, Àngels; Català Mallofré, Andreu (2017)
    Conference report
    Open Access
    Freezing of gait (FOG) is one of the most incapacitating symptoms among the motor alterations of Parkinson’s disease (PD). Manifesting FOG episodes reduce patients’ quality of life and their autonomy to perform daily living ...
  • A datalog framework for modeling relationship-based access control policies 

    Pasarella Sánchez, Ana Edelmira; Lobo, Jorge (Association for Computing Machinery (ACM), 2017)
    Conference report
    Open Access
    Relationships like friendship to limit access to resources have been part of social network applications since their beginnings. Describing access control policies in terms of relationships is not particular to social ...
  • Benchmarking the selection of the hidden-layer weights in extreme learning machines 

    Romero Merino, Enrique (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    Conference report
    Open Access
    Recent years have seen a growing interest in neural networks whose hidden-layer weights are randomly selected, such as Extreme Learning Machines (ELMs). These models are motivated by their ease of development, high ...
  • Personalized questions, answers and grammars: aiding the search for relevant web information 

    Gatius Vila, Marta (Association for Computational Linguistics, 2017)
    Conference report
    Restricted access - publisher's policy
    This work is about guiding the user web search by generating most relevant questions, answers and grammars from web documents. The proposed approach is based on the representation of the main domain concepts as a set of ...
  • Semi-automatic colonic content analysis for diagnostic 

    Ceballos Inza, Víctor; Monclús Lahoya, Eva; Vázquez Alcocer, Pere Pau; Bendezú García, Álvaro; Mego, Marianela; Merino, Xavier; Azpiroz Vidaur, Fernando; Navazo Álvaro, Isabel (European Association for Computer Graphics (Eurographics), 2017)
    Conference lecture
    Open Access
    The analysis of the morphology and content of the gut is necessary in order to understand metabolic and functional gut activity and for diagnostic purposes. Magnetic resonance imaging (MRI) has become an important modality ...
