Incremental approximation computation in incomplete ordered decision systems
Approximation computation is a critical step in rough sets theory used in knowledge discovery and other related tasks. In practical applications, an information system often evolves over time by the variation of attributes or objects. Effectively computing approximations is vital in data mining. Dominance-based rough set approach can handle information with preference-ordered attribute domain, ...
متن کاملLimited Dominance-based Rough Set Model and Knowledge Reductions in Incomplete Decision System
In this paper, we introduce a new rough set approach, which is called the limited dominance-based rough set model into the incomplete decision system. The limited dominance relation is different from the traditional dominance relation in the incomplete environment because we are on the assumption that the unknown value can only be compared with the maximal or minimal value in the domain of the ...
متن کاملApproach to approximate distribution reduct in incomplete ordered decision system
The original rough set model cannot be used to deal with the incomplete information systems. Nevertheless, by relaxing the indiscernibility relation to more general binary relations, many improved rough set models have been successfully applied into the incomplete information systems for knowledge acquisition. This article presents an explorative research focusing on the transition from incompl...

On Dominance Relations in Disjunctive Set-Valued Ordered Information Systems
Set-valued information systems are generalized models of single-valued information systems. Its semantic interpretation can be classified into two categories: disjunctive and conjunctive. We focus on the former in this paper. By introducing four types of dominance relations to the disjunctive set-valued information systems, we establish a dominance-based rough sets approach, which is mainly bas...
