Attribute reduction based on intuitionistic fuzzy rough set
Jixue Hua · Kongzhi yu juece · 2009
To the issue of lower approximation proposed by Jensen,an improved definition of lower approximation described with fuzzy equivalent classes is proposed and extended to intuitionistic fuzzy approximation space firstly.The notion of positive region and relative reduct in classical rough set are generalized to the intuitionistic fuzzy information system and a heuristic algorithm for attribute reduction based on intuitionistic fuzzy rough set is proposed.Finally,two particular experiments verify the rationality and effectiveness of the developed algorithm.
