Abstract :
Rough set can be established on mutually-inversistic set theory constructed by the author, forming mutually-inversistic rough set. The main functionality of traditional rough set is to mine decision rules from lower approximations. From the point of view of mutually-inversistic rough set, it is to mine mutually inverse being contained connections from lower approximations. Mutually-inversistic rough set can also mine mutually inverse intersection connections from upper approximations. It can mine not only the strong mutually inverse intersection connections, but also weak mutually inverse intersection connections. It can also make chain reasoning on the mutually inverse intersection connections mined. Therefore, mutually-inversistic rough set excels traditional rough set in functionality.
