Maximum Consistent Block Based Variable Precision Rough Set Model and Attribute Reduction

open access: yesJisuanji kexue yu tansuo, 2020
In this paper, attribute reduction of incomplete information system is studied. Firstly, optimistic and pessimistic generalized variable precision rough set models based on maximal consistent blocks are constructed.

On numerical characterizations of the topological reduction of incomplete information systems based on evidence theory

open access: yesJournal of Intelligent Systems, 2023
Knowledge reduction of information systems is one of the most important parts of rough set theory in real-world applications. Based on the connections between the rough set theory and the theory of topology, a kind of topological reduction of incomplete ...

Attribute Reduction in Incomplete Information System based on Rough Set Theory Using Fuzzy Imperialist Competitive Algorithm [PDF]

open access: yesJournal of Information Technology Management, 2017
In recent years, rough set theory has been considered as a strong solution to solve artificial intelligence problem such as data mining. But, the classic rough set theory is not effective in the case of attribute reduction in incomplete information ...

An inconsistency control system based on incomplete pairwise comparison matrices [PDF]

open access: yes, 2011
Incomplete pairwise comparison matrix was introduced by Harker in 1987 for the case in which the decision maker does not fill in the whole matrix completely due to, e.g., time limitations.
