A generalized framework to consider positive and negative attributes in formal concept analysis
Rodríguez Jiménez, José Manuel; Cordero-Ortega, Pablo
; Enciso-García-Oliveros, Manuel; Mora-Bonilla, Ángel (2014-10-23)
In Formal Concept Analysis the classical formal context is analized taking into account only the positive information, i.e. the presence of a property in an object. Nevertheless, the no presence of a property in an object ... -
Formal concept analysis and structures underlying quantum logics
Krídlo, Ondrej; Ojeda-Aciego, Manuel (2018-06-04)
A Hilbert space $H$ induces a formal context, the Hilbert formal context $\overline H$, whose associated concept lattice is isomorphic to the lattice of closed subspaces of $H$. This set of closed subspaces, denoted $\mathcal ... -
Ordering objects via attribute preferences
Cabrera, Inma P.; Ojeda-Aciego, Manuel; Pocs, Jozef (2014-10-29)
We apply recent results on the construction of suitable orderings for the existence of right adjoint to the analysis of the following problem: given a preference ordering on the set of attributes of a given context, we ... -
Relation-based Galois connections: towards the residual of a relation
Cabrera, Inma P.; Cordero-Ortega, Pablo; Ojeda-Aciego, Manuel (2017-09-29)
We explore a suitable generalization of the notion of Galois connection in which their components are binary relations. Many different approaches are possible depending both on the (pre-)order relation between subsets in ... -
Removing redundancy for attribute implications in data with grades
Mora-Bonilla, Ángel; Rodríguez-Lorenzo, Estrella; Cordero-Ortega, Pablo; Enciso-García-Oliveros, Manuel (Cristina Alcalde, Humberto Bustince, Francisco Javier Fernández, 2016)
Reasoning with if-then rules –in particular, with those taking from of implications between conjunctions of attributes– is crucial in many disciplines ranging from theoretical computer science to applications. One of the ... -
The direct-optimal basis via reductions
Rodríguez-Lorenzo, Estrella; Bertet, Karell; Cordero-Ortega, Pablo; Enciso-García-Oliveros, Manuel; Mora-Bonilla, Ángel (2014-10-23)
Formal Concept Analysis has become a real approach in the trend Information-Knowledge-Wisdom. It turns around the mining of a data set to built a concept lattice which provides an strong structure of the knowledge. ...
