限制优势关系下的加权多粒度粗糙分析方法
Rough analysis model of weighted multi-granularity based on limited dominance relation
摘要
Abstract
As an extension of the multi-granularity rough set, a rough analysis model of weighted multi-granularity based on limited dominance relation is proposed. Firstly, the limitation of the rough set based on dominance relation and multi-granularity rough set is analyzed and the limited dominance relation is introduced to improve the weighted multi-granularity rough set for high-dimensional or distributed systems with incomplete and reference attribution, making the preference relations of properties and the difference among the granularities fully considered. The rough approximations of know-ledge are acquired and the relationship with the optimistic and pessimistic model is discussed. Then, relevant theorems and properties are proved. Finally, the experimental results show the feasibility and effectiveness of the method.关键词
