Chunlai Zhou, Zhigang Li, Yuejin Meng, Qinglong Meng · 2005
In this paper, a data mining algorithm based on rough set theory (RS) is discussed, which is used to extract decision-making rule from data set. The basic concepts of RS are introduced and used in the algorithm. An example that uses the algorithm to acquire designing rule from the knowledge database of relay expert system is discussed in the paper.
