Misinformation Correction Maximization Problem with Edge Addition in Social Networks [PDF]

open access: yesJisuanji kexue, 2022
The popularity of online social networks such as Wechat has aroused people’s more attention to information diffusion.The spread of misinformation in social networks may lead to serious consequences,such as economic losses and public panic.Therefore ...

Generalized Lower and Upper Approximations in Quantales [PDF]

open access: yesJournal of Applied Mathematics, 2012
We introduce the concepts of set‐valued homomorphism and strong set‐valued homomorphism of a quantale which are the extended notions of congruence and complete congruence, respectively. The properties of generalized lower and upper approximations, constructed by a set‐valued mapping, are discussed.

THE IMPLEMENTATION OF A ROUGH SET OF PROJECTIVE MODULE

open access: yesBarekeng, 2023
In ring and module theory, one concept is the projective module. A module is said to be projective if it is a direct sum of independent modules. (U, R)  is an approximation space with non-empty set  and equivalence relation   If X subset U, we can form

Roughness in Membership Continuous Function

open access: yesمجلة المختار للعلوم, 2021
In this paper, we introduce the new definition of rough membership function using continuous function and we discuss several concepts and properties of rough continuous set value functions as new results on rough continuous function and membership ...

Sequential Three-Way Decision of Tolerance- Based Multi-Granularity Fuzzy-Rough Sets

open access: yesIEEE Access, 2019
The existing three-way decision-making methods are classified into two classes-a single one-step three-way decision-making and a sequential, multi-step three-way decision-making, and this paper studies the latter.

Cost-sensitive Multigranulation Approximation of Neighborhood Rough Fuzzy Sets [PDF]

open access: yesJisuanji kexue, 2023
Multigranulation neighborhood rough sets are a new data processing mode in the theory of neighborhood rough sets,in which the target concept can be characterized by upper/lower approximate boundaries of optimistic and pessimistic,respectively ...

Rule induction based on rough sets from information tables having continuous domains

open access: yesCAAI Transactions on Intelligence Technology, 2019
Information tables having continuous domains are handled by neighborhood rough sets. Two approximations in complete information tables are extended to handle incomplete information.

Covering-Based Rough Single Valued Neutrosophic Sets [PDF]

open access: yesNeutrosophic Sets and Systems, 2017
Rough sets theory is a powerful tool to deal with uncertainty and incompleteness of knowledge in information systems. Wang et al. proposed single valued neutrosophic sets as an extension of intuitionistic fuzzy sets to deal with real-world problems.
