-granular variable precision fuzzy rough sets based on overlap and grouping functions
Wei Li, Bin Yang, Junsheng Qiao
Since Bustince et al. introduced the concepts of overlap and grouping functions, these two types of aggregation functions have attracted a lot of interest in both theory and applic…
On three types of -fuzzy -covering-based rough sets
Wei Li, Bin Yang, Junsheng Qiao
In this paper, we mainly construct three types of -fuzzy -covering-based rough set models and study the axiom sets, matrix representations and interdependency of these three…
Some neighborhood-related fuzzy covering-based rough set models and their applications for decision making
Gongao Qi, Bin Yang, Wei Li
Fuzzy rough set (FRS) has a great effect on data mining processes and the fuzzy logical operators play a key role in the development of FRS theory. In order to further generalize t…
Some properties of fuzzy -norm and vague -norm
Haohao Wang, Bin Yang, Wei Li
Rosenfeld defined a fuzzy subgroup of group as a fuzzy subset of with two special conditions attached\cite{Rosenfeld1971Fuzzysubgroups}. In this paper, we introduce the fuz…
Connectivity for matroids based on rough sets
Bin Yang, William Zhu
In mathematics and computer science, connectivity is one of the basic concepts of matroid theory: it asks for the minimum number of elements which need to be removed to disconnect…
Rough matroids based on coverings
Bin Yang, Hong Zhao, William Zhu
The introduction of covering-based rough sets has made a substantial contribution to the classical rough sets. However, many vital problems in rough sets, including attribution red…
Matroidal structure of generalized rough sets based on symmetric and transitive relations
Bin Yang, William Zhu
Rough sets are efficient for data pre-process in data mining. Lower and upper approximations are two core concepts of rough sets. This paper studies generalized rough sets based on…
