Abstract :
Rough set theory is an efficient information processing tool used in the discovery of data dependencies. It evaluates the importance of attributes, discovers the patterns of data, reduces all redundant objects and attributes, and seeks the minimum subset of attributes. This paper presents a method for attribute reduction on combination of rough set and neighborhood systems. Neighborhood decision system is investigated by considering relation between two ways and introducing two neighborhood approximation operators. Illustrative results for some databases in UCI repository of machine learning databases provided good results.
