多对象迁移下动态覆盖决策信息系统的知识约简
Knowledge reduction of dynamic covering decision information systems with immigration of more objects
摘要:
作为动态覆盖决策信息系统知识约简的一个重要步骤,研究集合的近似计算是一个重要的课题。在本文中,我们提出了增量方法来计算动态覆盖的1型和2型特征矩阵,这些覆盖的基数随着更多对象的迁移而增加。给出了在动态覆盖近似空间中计算集合的第二和第六下近似和上近似的增量算法。
英文摘要:
In practical situations, it is of interest to investigate computing approximations of sets as an important step of knowledge reduction of dynamic covering decision information systems. In this paper, we present incremental approaches to computing the type-1 and type-2 characteristic matrices of dynamic coverings whose cardinalities increase with immigration of more objects. We also present the incremental algorithms of computing the second and sixth lower and upper approximations of sets in dynamic covering approximation spaces.
