摘 要: | Rough集以等价关系为基础建立了知识表达系统和知识发现算法,相容关系是等价关系的推广。从粒矩阵
角度定义了相容关系的知识表达系统、知识的依赖性与关联规则发现方法。在此基础上,把粒矩阵运算由等价关系推
广到相容关系。

Granular Matrix-based Knowledge Representation for Tolerance Relation |
| |
Abstract: | Based on equivalence relation, knowledge representation system (KRS) and knowledge reduction algorithms
were established by rough set theory (RST). Tolerance relation is extension of equivalence relation. KRS, upper and
lower approximation, knowledge dependency and discovery of association rules of tolerance system were defined and
computed by granular matrix. |
