    • Evolution in time of L-fuzzy context sequences 

      Alcalde, Cristina; Burusco Juandeaburre, Ana Upna Orcid; Bustince Sola, Humberto Upna Orcid; Jurío Munárriz, Aránzazu Upna Orcid; Sanz Delgado, José Antonio Upna Orcid (Elsevier, 2016)   Artículo / Artikulua  OpenAccess
      In this work, we consider a complete lattice L and we study L-fuzzy context sequences which represent the evolution in time of an L-fuzzy context. To carry out this study, in the first part of the paper, we consider n-ary ...

    • Knowledge extraction from L-fuzzy contexts associated with criteria evolving over time 

      Alcalde, Cristina; Burusco Juandeaburre, Ana Upna Orcid (IOS Press, 2020)   Artículo / Artikulua  OpenAccess
      Information extracted from L-fuzzy contexts is substantially improved by taking into account different points of view, which can roughly be represented by criteria. This work addresses the general study of L-fuzzy contexts ...

    • Linking mathematical morphology and L-fuzzy concepts 

      Alcalde, Cristina; Burusco Juandeaburre, Ana Upna Orcid; Bustince Sola, Humberto Upna Orcid; Fuentes González, Ramón Upna Orcid; Sesma Sara, Mikel Upna Orcid (World Scientific, 2017)   Artículo / Artikulua  OpenAccess
      In this paper we study the relation between L-fuzzy morphology and L-fuzzy concepts over complete lattices. In particular, we show how the erosion and dilation operators of the former can be understood in terms of the ...

    • Multivalued contexts associated with criteria 

      Alcalde, Cristina; Burusco Juandeaburre, Ana Upna Orcid (Taylor & Francis, 2018)   Artículo / Artikulua  OpenAccess
      We are interested in the study of L-fuzzy contexts taking into account different criteria. These contexts arise when we want to analyze the relationship between objects and attributes from different points of view. ...

    • Reduction of the size of L-fuzzy contexts. A tool for differential diagnoses of diseases 

      Alcalde, Cristina; Burusco Juandeaburre, Ana Upna Orcid (Taylor & Francis, 2019)   Artículo / Artikulua  OpenAccess
      Information extraction from an L-fuzzy context becomes a hard problem when we work with a large set of objects and/or attributes. The goal of this paper is to present two different and complementary techniques to reduce ...

    • Trend analysis in L-fuzzy contexts with absent values 

      Alcalde, Cristina; Burusco Juandeaburre, Ana Upna Orcid; Bustince Sola, Humberto Upna Orcid; Sesma Sara, Mikel Upna Orcid (University of Sistan and Baluchestan (Irán), 2020)   Artículo / Artikulua  OpenAccess
      Sometimes we have to work with L-fuzzy context sequences where one or more values are missing. These sequences can represent, among other things, the evolution in time of an L-fuzzy context. The studies of tendencies that ...

    • Use of Choquet integrals in multivalued contexts 

      Burusco Juandeaburre, Ana Upna Orcid; Alcalde, Cristina (Springer, 2020)   Artículo / Artikulua  OpenAccess
      In this work, multivalued contexts are studied, in which the different observations are related to each other. Continuing the studies already carried out in previous works, the use of Choquet integrals can be an adequate ...
