Decision attribute reduction of interval-valued information system
Keyun Qin · Computer Engineering and Applications Journal · 2009
A new variable precision tolerance relation is defined in interval-valued information system by similarity grade of attribute’s interval-value,based on the variable precision tolerance relation the problems of decision attribute reduction and relative decision attribute reduction in interval-valued information system are studied,from which an approach for decision attribute reduction and relative decision attribute reduction is provided in interval-valued information system.
