On the basis of rough sets, by considering both the dynamic characteristics of the set x and the statistics information in the knowledge database, this paper constructs bidirectional probabilistic PS-rough sets model in probabilistic approximation space, discusses property and theorems of PS-rough sets, proves that PS-rough sets is the further extension of S-rough sets and Z.Pawlak rough sets, S-rough...
This paper investigates the underlying patterns in data derived from the International Tobacco Control Four Country Survey. The intent of the paper is to determine which attributes have the greatest impact on smokers' plans to quit and their attempts to quit.
