    • Geometrical aggregation of finite fuzzy sets 

      Campión Arrastia, María Jesús Upna; García Catalán, Olga Raquel Upna; Induráin Eraso, Esteban; Lizasoain Iriso, María Inmaculada Upna; Raventós Pujol, Armajac; Valero, Óscar (Elsevier, 2018)   Artículo / Artikulua
      A fuzzy set on a finite universe can be interpreted as a vector in a unit cube. This gives rise to a huge variety of approaches in order to aggregate finite fuzzy sets or to modify a given one. We analyze several geometrical ...
    • The interval-valued Choquet integral based on admissible permutations 

      Paternain Dallo, Daniel Upna; Miguel Turullols, Laura de Upna; Ochoa Lezaun, Gustavo Upna; Lizasoain Iriso, María Inmaculada Upna; Mesiar, Radko; Bustince Sola, Humberto Upna (IEEE, 2018)   Artículo / Artikulua
      Aggregation or fusion of interval data is not a trivial task, since the necessity of arranging data arises in many aggregation functions, such as OWA operators or the Choquet integral. Some arranging procedures have been ...
    • Orness for idempotent aggregation functions 

      Legarreta, Leire; Lizasoain Iriso, María Inmaculada Upna; Mardones Pérez, Iraide (MDPI, 2017)   Artículo / Artikulua  OpenAccess
      Aggregation functions are mathematical operators that merge given data in order to obtain a global value that preserves the information given by the data as much as possible. In most practical applications, this value is ...
    • Orness measurements for lattice m-dimensional interval-valued OWA operators 

      Miguel Turullols, Laura de Upna; Paternain Dallo, Daniel Upna; Lizasoain Iriso, María Inmaculada Upna; Ochoa Lezaun, Gustavo Upna; Bustince Sola, Humberto Upna (Elsevier, 2018)   Artículo / Artikulua
      Ordered weighted average (OWA) operators are commonly used to aggregate information in multiple situations, such as decision making problems or image processing tasks. The great variety of weights that can be chosen to ...
    • Some characterizations of lattice OWA operators 

      Miguel Turullols, Laura de Upna; Paternain Dallo, Daniel Upna; Lizasoain Iriso, María Inmaculada Upna; Ochoa Lezaun, Gustavo Upna; Bustince Sola, Humberto Upna (World Scientific Publishing Company, 2017)   Artículo / Artikulua  OpenAccess
      Ordered Weighted Averaging (OWA) operators are a family of aggregation which fusion data. If the data are real numbers, then OWA operators can be characterized either as an special kind of Choquet integral or simply as ...
    • Teoría de Clifford en el anillo de Burnside 

      Lizasoain Iriso, María Inmaculada Upna (Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 1995)   Tesis doctoral / Doktoretza tesia  OpenAccess
