  • Characterizations of logarithmic advice complexity classes 

    Balcázar Navarro, José Luis; Hermo Huguet, Montserrat; Mayordomo, Elvira (1991-12-13)
    Research report
    Open Access
    The complexity classes P/log and Full-P/log, corresponding to the two standard forms of logarithmic advice for polynomial time, are studied. Characterizations are found in terms of Kolmogorov-simple circuits, bounded query ...

  • A Question-driven Information system adaptable via Information Extraction techniques 

    Sapena Masip, Emilio; González Bermúdez, Meritxell; Padró, Lluís; Turmo Borras, Jorge (2008-06-13)
    Research report
    Open Access
    This paper presents a system is composed by two main parts: The Information Extraction Process, which crawls the web and extracts all relevant knowledge that is then stored in the database, and the Question Processor which ...
  • A topological comparison of surface extraction algorithms 

    Andújar Gran, Carlos Antonio; Brunet Crosa, Pere; Fairén González, Marta; Navazo Álvaro, Isabel; Vinacua Pla, Álvaro (2021-10-22)
    Research report
    Open Access
    In many application areas, it is useful to convert the discrete information stored in the nodes of a regular grid into a continuous boundary model. Isosurface extraction algorithms differ on how the discrete information ...
  • End-to-End speech translation with pre-trained models and adapters: UPC at IWSLT 2021 

    Gallego Olsina, Gerard Ion; Tsiamas, Ioannis; Escolano Peinado, Carlos; Fonollosa, José A. R.; Ruiz Costa-Jussà, Marta (2021-06-28)
    Research report
    Open Access
    This paper describes the submission to the IWSLT 2021 offline speech translation task by the UPC Machine Translation group. The task consists of building a system capable of translating English audio recordings extracted ...
  • Gender bias in multilingual neural machine translation: The architecture matters 

    Ruiz Costa-Jussà, Marta; Escolano Peinado, Carlos; Basta, Christine Raouf Saad; Ferrando Monsonís, Javier; Batlle, Roser; Kharitonova, Ksenia (2020-12-24)
    Research report
    Open Access
    Multilingual Neural Machine Translation architectures mainly differ in the amount of sharing modules and parameters among languages. In this paper, and from an algorithmic perspective, we explore if the chosen architecture, ...
  • 1849-2016 - IEEE Standard for eXtensible Event Stream (XES) for achieving interoperability in event logs and event streams 

    Van der Aalst, Wil M.P.; Günther, Christian; Bose, J. C.; Carmona Vargas, Josep; Dumas, Marlon; van Geffen, Frank; Goel, Sukriti; Guzzo, Antonella; Khalaf, Rania; Kuhn, Rudolf; Lehto, Teemu; Mannhardt, Felix (2016-09-22)

  • Representació del coneixement: una síntesi 

    Sànchez-Marrè, Miquel (1991-11)
    Research report
    Open Access
    En aquesta síntesi es presenta una visió global dels principals formalismes de representació del coneixement, que s'han desenvolupat al llarg de la història de la Intel·ligència Artificial. Aquesta revisió ve precedida ...
  • Adaptive logspace reducibility and parallel time 

    Álvarez Faura, M. del Carme; Balcázar Navarro, José Luis; Jenner, Birgit (1991-11)
    Research report
    Open Access
    We discuss two notions of functional oracle for logarithmic space-bounded machines, which differ in whether there is only one oracle tape for both the query and the answer or a separate tape for the answer, which can still ...
  • Dos aproximaciones a la adquisición del conocimiento léxico y conceptual para sistemas de procesamiento del lenguaje natural

  • The design of a parallel algorithm to solve the word problem for the free partially commutative groups 

    Gabarró Vallès, Joaquim (1991-10-15)
    Research report
    Open Access
    We develop a parallel algorithm to solve the word problem for free partially commutative groups. These groups were introduced by C. Wrathall to generalize free groups. We represent the elements of these groups as a certain ...
