Knowledge reduction of dynamic covering decision information systems with varying attribute values
Mingjie Cai
Knowledge reduction of dynamic covering information systems involves with the time in practical situations. In this paper, we provide incremental approaches to computing the type-1…
Some new similarity measures for hesitant fuzzy sets and their applications in multiple attribute decision making
Xiaoqiang Zhou, Qingguo Li
Similarity measure is a very important topic in fuzzy set theory. Torra (2010) proposed the notion of hesitant fuzzy set(HFS), which is a generalization of the notion of Zadeh' fuz…
The construction of characteristic matrixes of dynamic coverings using an incremental approach
Guangming Lang, Qingguo Li, Lankun Guo +1
The covering approximation space evolves in time due to the explosion of the information, and the characteristic matrixes of coverings viewed as an effective approach to approximat…
Compression of dynamic fuzzy relation information systems
Mingjie Cai, Qingguo Li, Guangming Lang
This paper further investigates the data compression of fuzzy relation information systems. First, we introduce an algorithm for constructing the homomorphism between fuzzy relatio…
Data compression of dynamic set-valued information systems
Guangming Lang, Qingguo Li
This paper further investigates the set-valued information system. First, we bring forward three tolerance relations for set-valued information systems and explore their basic prop…
