AbstractAttributes reduction based on rough set is interesting research area. However, the attributes reduction algorithms based on rough set is done on the discrete domain decision tables (that is applied discretization methods). In recent years, some researchs on fuzzy rough set based directly attribute reduction in numeric domain decision tables have been studied. This paper proposes fuzzy rough set based directly attribute reduction method in numeric domain decision tables. The experiment results showed that the fuzzy rough set method has better classification accuracy than rough set theory.
