This paper aims to contribute to the extension of classical Formal Concept Analysis (FCA),
allowing the management of unknown information. In a preliminary paper, we define a new …

The computation of (if-then) rules relating the most representative variables of a given
dataset is a relevant goal in different areas of data analysis such as stock market prediction …

The aim of this paper is to extend closure systems from being crisp sets with certain fuzzy
properties to proper fuzzy sets. The presentation of the paper shows a thorough discussion …

Two alternative definitions of closure system in complete fuzzy lattices are introduced, first as
a crisp set and then as a fuzzy one. It is valuated in a complete Heyting algebra and follows …

The concept of closure operator is key in several branches of mathematics. In this paper,
closure operators are extended to relational structures, more specifically to fuzzy relations in …

The detection of redundant or irrelevant variables (attributes) in datasets becomes essential
in different frameworks, such as in Formal Concept Analysis (FCA). However, removing such …

Usually, datasets contain imprecise data (noise), which can produce unsuspected results on
the considered mappings. For instance, this can happen with the infimum and supremum …

In this paper, closure operators obtained from functions having some properties on bounded
lattices are defined. By this way, it is aimed to generalize the notions T and U-closure …

We generalize the notion of quasi-closed element to fuzzy posets in two stages: First, in the
crisp style in which each element in a given universe either is quasi-closed or not. Second …
