The survey of fuzzy sets theory and rough sets theory use to data mining technique

The combination of fuzzy sets theory and rough sets theory use to data mining technique due to transfer vague and imprecise data. From the previous literature, rough set theory can only operate effectively with dataset containing discrete value. As most dataset contain real-valued features, it is essential for employing by standard fuzzification techniques which are called modified minimization entropy principle algorithm (MMEPA) is proposed to construct membership function of fuzzy sets.
