Knowledge Granulation in Interval-Valued Information Systems Based on Maximal Consistent Blockson. In this paper, we investigate partial relations and propose the concept of knowledge granulation based on the maximal consistent block in interval-valued information systems. The knowledge granulation can provide important approaches to measuring the discernibility of different knowledge in inte

Rough Set Theory on Topological Spaces known topological concepts are closely related to Rough Sets and generalize the Rough sets in the frame work of Topological Spaces. We presented the properties of Quasi-Discrete topology and Π.-Roughsets.

Approximate Reduction for the Interval-Valued Decision Tablee, rather than one record, to determine their decision classes, because the class label of only one record is meaningless. Based on the above discussion, interval-valued rough set is introduced. From the algebra view, we define the related concepts and prove the properties for the interval-valued re

Global Best Artificial Bee Colony for Minimal Test Cost Attribute Reductionntly, several algorithms are proposed to address this problem, and can get acceptable results in most cases. However, the effectiveness of the algorithms for large datasets are often unacceptable. In this paper, we propose a global best artificial bee colony algorithm with an improved solution searc
