An Approximate Approach to Attribute Reduction
The attribute reduction is one of key processes for knowledge acquisition. This paper deals with approximate approach to attribute reduction. The concept of minimal discernible attributes set is introduced and a calculation method for it is investigated. And then, the judgment theorem with respect to keeping positive region invariability is obtained, from which an approximate approach to attrib...
متن کاملAttribute Reduction in Incomplete Information Systems
Through changing the equivalence relation of objects to reflexive and symmetric binary relation in the incomplete information system, a cumulative variable precision rough set model is proposed. The basic properties of β lower and β upper cumulative approximation operators are investigated. β upper, and β lower distribution consistent set are explored for defining β upper, and β lower distribut...
متن کاملFast Approximate Attribute Reduction with MapReduce
Massive data processing is a challenging problem in the age of big data. Traditional attribute reduction algorithms are generally time-consuming when facing massive data. For fast processing, we introduce a parallel fast approximate attribute reduction algorithm with MapReduce. We divide the original data into many small blocks, and use reduction algorithm for each block. The reduction algorith...
متن کاملAttribute reduction in tolerance information systems based on evidence theory
Attribute reduction is one of the most important problems in rough set theory. This paper deals with attribute reduction in tolerance information systems based on Dempster-shafter theory of evidence. The concepts of plausibility consistent set and belief consistent set are introduced in tolerance information systems. Furthermore, relative plausibility reduction and belief reduction are discusse...
متن کاملAttribute Reduction and Information Granularity
This work was supported by Science and Technology Commission of Shanghai Municipality, No.705931 ABSTRACT In the view of granularity, this paper analyzes the influence of three attribute reducts on an information system, finding that the possible reduct and − μ decision reduct will make the granule view coarser, while discernible reduct will not change the granule view. In addition, we investig...
