Study Of Data Mining Method Based On Rough Set Theory

Rough set theory is a new mathematical tool that deals with vagueness and uncertainty. At present, the data mining method based on rough set theory has become one of the main methods of data mining. Firstly, this article introduces the basic concepts of data mining and rough set theory. Secondly, it presents an improved algorithm of attribute reduction. Finally, it gives an algorithm of data mining based on rough set theory, and a practical example is given to illustrate the proposed algorithm and verifies its Tightness.
