T-Rough Sets Based on the Lattices
The aim of this paper is to introduce and study set- valued homomorphism on lattices and T-rough lattice with respect to a sublattice. This paper deals with T-rough set approach on the lattice theory. The result of this study contributes to, T-rough fuzzy set and approximation theory and proved in several papers. Keywords: approximation space; lattice; prime ideal; rough ideal; T-rough set; set...
متن کاملLattice Structure of Variable Precision Rough Sets
The main purpose of this paper is to study the lattice structure of variable precision rough sets. The notion of variation in precision of rough sets have been further extended to variable precision rough set with variable classification error and its algebraic properties are also studied.

متن کاملKnowledge Reduction and Probability Rule Induction Based on Rough Sets
Rough sets theory is a traditional method for information reduction and rules acquisition under the circumstance of incomplete information. In this paper, the new version of reduction algorithm based on discernibility matrix was proposed through revising the common algorithm. The new algorithm is more efficient in finding out the criminal attribute. In the decision information system,using the ...
متن کاملMaintenance of Reductsin the Variable Precision Rough Sets
Deenitions of a reduct for a single object, decision class and all objects of decision table for the variable precision rough sets model are introduced. The deenitions have a property that the set of prime implicants of minimal disjunctive normal form of a discernibility function is equal to the set of reducts. Thus the problem of reducts maintenance in dynamically extended information systems ...
