Optimal Granularity Selection and Attribute Reduction in Meso-granularity Space [PDF]
Jisuanji kexue, 2023 The conventional formal concept analysis adopts a meso-granularity formal context to meet the requirements of cross-layer granulation of data.However,it does not effectively combine the search for optimal granularity with attribute reduction,nor does it ...

Simple Undirected Graphs as Formal Contexts [PDF]
, 2015 The adjacency matrix of a graph is interpreted as a formal context. Then, the counterpart of Formal Concept Analysis (FCA) tools are introduced in graph theory. Moreover, a formal context is seen as a Boolean information table, the structure at the basis of Rough Set Theory (RST). Hence, we also apply RST tools to graphs.

Consistent Sets of Soft Contexts Defined by Soft Sets
Mathematics, 2019 We introduce the notion of consistent sets of soft contexts and investigate its characterizations. For the purpose of studying the characterizations of consistent sets, we introduce the notions of 1 0 and 2 0 classes of independent ...

Fuzzy Implication and Functional Dependency on Formal Context
Jurnal Matematika Integratif, 2020 Fuzzy formal concept analysis(FFCA) is a development of formal concept analysis(FCA) with the degree of relation between objects and attributes. Using FCA approach, we will investigate the condition logical implication for fuzzy functional dependency. We

Knowledge cores in large formal contexts
Annals of Mathematics and Artificial Intelligence, 2022 AbstractKnowledge computation tasks, such as computing a base of valid implications, are often infeasible for large data sets. This is in particular true when deriving canonical bases in formal concept analysis (FCA). Therefore, it is necessary to find techniques that on the one hand reduce the data set size, but on the other hand preserve enough ...

Context-aware approach for formal verification
EAI Endorsed Transactions on Context-aware Systems and Applications, 2016 The Context-aware approach has proven to be an effective technique for software model-checking verification. It focuses on the explicit modelling of environment as one or more contexts.
