  • Optimality of syntactic dependency distances 

    Ferrer Cancho, Ramon; Gómez Rodríguez, Carlos; Esteban Ángeles, Juan Luis; Alemany Puig, Lluís (American Institute of Physics (AIP), 2022-01-01)
    Article
    Open Access
    It is often stated that human languages, as other biological systems, are shaped by cost-cutting pressures but, to what extent? Attempts to quantify the degree of optimality of languages by means of an optimality score ...
  • Leveraging contextual embeddings and self-attention neural networks with bi-attention for sentiment analysis 

    Biesialska, Magdalena Marta; Biesialska, Katarzyna; Rybinski, Henryk (Springer Nature, 2021-12-01)
    Article
    Open Access
    People express their opinions and views in different and often ambiguous ways, hence the meaning of their words is often not explicitly stated and frequently depends on the context. Therefore, it is difficult for machines ...
  • Non-technical losses detection in energy consumption focusing on energy recovery and explainability 

    Coma Puig, Bernat; Carmona Vargas, Josep (2021-09-29)
    Article
    Open Access
    Non-technical losses (NTL) is a problem that many utility companies try to solve, often using black-box supervised classifcation algorithms. In general, this approach achieves good results. However, in practice, NTL detection ...
  • Minimum projective linearizations of trees in linear time 

    Alemany Puig, Lluís; Esteban Ángeles, Juan Luis; Ferrer Cancho, Ramon (2022-03)
    Article
    Open Access
    The Minimum Linear Arrangement problem (MLA) consists of finding a mapping π from vertices of a graph to distinct integers that minimizes {u,v}∈E |π(u) − π(v)|. In that setting, vertices are often assumed to lie on a ...
  • Visual analysis of large-scale protein-ligand interaction data 

    Schatz, Karsten; Franco Moreno, Juan José; Schäfer, Marco; Rose, Alexander S.; Ferrario, Valerio; Pleiss, Jürgen; Vázquez Alcocer, Pere Pau; Ertl, Thomas; Krone, Michael (2021-09)
    Article
    Open Access
    When studying protein-ligand interactions, many different factors can influence the behaviour of the protein as well as the ligands. Molecular visualisation tools typically concentrate on the movement of single ligand ...
  • Unleashing textual descriptions of business processes 

    Sànchez-Ferreres, Josep; Burattin, Andrea; Carmona Vargas, Josep; Montali, Marco; Padró, Lluís; Quishpi Betún, Luis Hernán (2021-12)
    Article
    Restricted access - publisher's policy
    Textual descriptions of processes are ubiquitous in organizations, so that documentation of the important processes can be accessible to anyone involved. Unfortunately, the value of this rich data source is hampered by the ...
  • Cumulated burden of Covid-19 in Spain from a Bayesian perspective 

    Moriña, David; Fernandez Fontelo, Amanda; Cabaña Nigro, Ana Alejandra; Arratia Quesada, Argimiro Alejandro; Ávalos Villaseñor, Gustavo Eduardo; Puig, Pedro (2021-12)
    Article
    Open Access
    Background The main goal of this work is to estimate the actual number of cases of Covid-19 in Spain in the period 01-31-2020/06-01-2020 by Autonomous Communities. Based on these estimates, this work allows us to accurately ...
  • Knowledge-based segmentation to improve accuracy and explainability in non-technical losses detection 

    Calvo Ibáñez, Albert; Coma Puig, Bernat; Carmona Vargas, Josep; Arias Vicente, Marta (2020-10-30)
    Article
    Open Access
    Utility companies have a great interest in identifying energy losses. Here, we focus on Non-Technical Losses (NTL), which refer to losses caused by utility theft or meter errors. Typically, utility companies resort to ...
  • Estimating player positions from padel high-angle videos: Accuracy comparison of recent computer vision methods 

    Javadiha, Mohammadreza; Lacasa Claver, Enrique; Ric Díez, Angel; Andújar Gran, Carlos Antonio; Susín Sánchez, Antonio (Multidisciplinary Digital Publishing Institute (MDPI), 2021-05-12)
    Article
    Open Access
    The estimation of player positions is key for performance analysis in sport. In this paper, we focus on image-based, single-angle, player position estimation in padel. Unlike tennis, the primary camera view in professional ...
  • Tychonis: a model-based approach to define and search for geometric events in space 

    Llopis, Marcel; Soria Guerrero, Manel; Franch Gutiérrez, Javier (2021-06)
    Article
    Restricted access - publisher's policy
    Space missions need software in order to be aware of the occurrence of geometric events in different phases of their project lifecycle. However, current software packages that provide capabilities to search for geometric ...
  • Multi-level dataflow-driven macro placement guided by RTL structure and analytical methods 

    Vidal Obiols, Alexandre; Cortadella, Jordi; Petit Silvestre, Jordi; Galcerán Oms, Marc; Martorell Cid, Ferran (2021-12)
    Article
    Open Access
    When RTL designers define the hierarchy of a system, they exploit their knowledge about the conceptual abstractions devised during the design and the functional interactions between the logical components. This valuable ...
  • Big data analytics in Agile software development: A systematic mapping study 

    Biesialska, Katarzyna; Franch Gutiérrez, Javier; Muntés Mulero, Víctor (Elsevier, 2021-04)
    Article
