摘要
为了说明粗糙集理论在不完备信息系统中的应用 ,给出了基于随机集的粗糙集方法 .提出了不完备信息系统的随机粗糙集的描述 ,讨论了不完备属性的随机集选择与系统的完备化的关系 ,并且介绍了一个求不完备属性的最大熵概率测度的算法 .
To show the application of the rough set theory, a rough set approach based on random sets is proposed. The description of an incomplete information system based on random rough set is explored. The relation between the selections of random set for the incomplet attributes and the completion of the system is discussed. The calculation of maximum-entropy probability measure of incomplete attributes is introduced.
