Abstract

Composite rough set aims to deal with multiple binary relations simultaneously in an information system. In this paper, probabilistic composite rough set is presented by introducing the probabilistic method to composite rough set. Then, the distribution attribute reduction method under probabilistic composite rough set is investigated. Examples are given to illustrate the method.
