Concept Learning Using Vague Concept Lattice

Neural Processing Letters, 2017
Recently, the theory of Formal Concept Analysis is extensively studied with bipolar fuzzy setting for adequate analysis of vagueness in fuzzy attributes via a defined sharp boundary. However, many real life data sets contain vague attributes (i.e. beautiful, bald, and tadpole) which cannot be defined through a sharp or restricted boundaries. To process

EMBEDDING OF CONCEPT LATTICE INTO ITS MIXED CONCEPT LATTICE

Advances in Mathematics: Scientific Journal, 2020
A BSTRACT . Formal Concept Analysis (FCA) is a method of analysis of object-attribute relational data and knowledge representation. In this paper, the foundations of FCA are extended and in particular mixed concept lattices are studied in depth.

Complex Fuzzy Concept Lattice

Neural Processing Letters, 2018
Recently, several properties of complex fuzzy sets are introduced to measure the changes in dynamic or periodic fuzzy attributes using its amplitude and phase terms. In this process, a problem is observed while discovering some of the meaningful information from the given complex data sets for the knowledge processing tasks.

A lattice-free concept lattice update algorithm

International Journal of General Systems, 2015
Upon a change of input data, one usually wants an update of output computed from the data rather than recomputing the whole output over again. In Formal Concept Analysis, update of concept lattice of input data when introducing new objects to the data can be done by any of the so-called incremental algorithms for computing concept lattice.

Rule extraction based on linguistic-valued intuitionistic fuzzy layered concept lattice

International Journal of Approximate Reasoning, 2021
As one of the research tools for data processing and knowledge discovery, concept lattice can effectively extract information. In daily life, due to the ambiguity and uncertainty of the decision environment, different experts may provide different ...

Decision Concept Lattice vs. Decision Trees and Random Forests

International Conference on Formal Concept Analysis, 2021
Decision trees and their ensembles are very popular models of supervised machine learning. In this paper we merge the ideas underlying decision trees, their ensembles and FCA by proposing a new supervised machine learning model which can be constructed ...

Describing hierarchy of concept lattice by using matrix

Information Sciences, 2021
Concept lattices (also called Galois lattices) are complete ones with the hierarchical order relation of the formal concepts defined by a formal context or Galois connection.

Conflict analysis under one-vote veto based on approximate three-way concept lattice

Information Sciences, 2020
Conflict analysis, which plays an important role in our society, has attracted more and more attentions. However, the existing conflict analysis models are not effective enough to evaluate the inconsistency degree of cliques that have more than two ...

Knowledge reduction methods of covering approximate spaces based on concept lattice

Knowledge-Based Systems, 2020
Both rough sets and concept lattices, which are two complementary tools in data analysis, are analyzed based on binary relations. The relations between rough sets and concept lattices are important research topic.
