基于矩阵的多粒度粗糙集上、下近似表示
Representation of upper and lower approximation on multi-granulation rough set based on matrix
摘要
Abstract
Multi-granulation rough set is developed based on the single granulation rough set. Aimed at comput-ing the upper and lower approximation of multi-granulation rough set,the paper proposed a new multi-granulari-ty binary matrix and investigated its related theories. Using the matrix, we can quickly calculate the upper and lower approximation of different granulation combinations.Finally,we verified the theory with examples.关键词
