On minimal sets of graded attribute implications

We explore the structure of non-redundant and minimal sets consisting of graded if-then rules. The rules serve as graded attribute implications in object-attribute incidence data and as similarity-based functional dependencies in a similarity-based generalization of the relational model of data. Based on our observations, we derive a polynomial-time algorithm which transforms a given finite set...

On sets of graded attribute implications with witnessed non-redundancy

We study properties of particular non-redundant sets of if-then rules describing dependencies between graded attributes. We introduce notions of saturation and witnessed non-redundancy of sets of graded attribute implications are show that bases of graded attribute implications given by systems of pseudo-intents correspond to non-redundant sets of graded attribute implications with saturated co...

Computing sets of graded attribute implications with witnessed non-redundancy

In this paper we extend our previous results on sets of graded attribute implications with witnessed non-redundancy. We assume finite residuated lattices as structures of truth degrees and use arbitrary idempotent truth-stressing linguistic hedges as parameters which influence the semantics of graded attribute implications. In this setting, we introduce algorithm which transforms any set of gra...

On Graded Nearness of Sets

In this article we present some mappings which can be used to measure the degree of inclusion of a set in a set and which characterize the binary relation of being-near-to, defined on finite sets of objects in line with Peters, Skowron, and Stepaniuk [12]. By means of these mappings, called inclusion functions in general, we extend the notion of nearness to the graded case where one can measure...

Probability Fuzzy Attribute Implications for Interval-Valued Fuzzy Sets

Recently Burusco introduced interval-valued fuzzy formal contexts into fuzzy formal concept analysis. The most interesting work mainly including fuzzy attribute implications from fuzzy formal context, however, were presented under the framework of residuated lattice. In this paper, we first show that the study of interval-valued fuzzy set can be fitted into the framework of residuated lattice. ...
