A generalized framework to consider positive and negative attributes in formal concept analysis
(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
(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 ... -
Numerical Implementation of Gradient Algorithms
(Springer, 2013)A numerical method for computational implementation of gradient dynamical systems is presented. The method is based upon the development of geometric integration numerical methods, which aim at preserving the dynamical ... -
Ordering objects via attribute preferences
(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
(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
(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
(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. ...
