Abstract
K. Shi (2002) puts forward S-rough sets (singular rough sets), S-rough sets has two kinds of forms as presented in K. Shi (2005): one direction S-rough sets (one direction singular rough sets), two direction S-rough sets (two direction singular rough sets); using assistant set in two direction S-rough sets, this paper gives rough recognition of the upper knowledge family on the assistant set of two direction S-rough sets, recognition model and recognition method, rough recognition of the lower knowledge family on the assistant set of two direction S-rough sets, recognition model and recognition method. It presents knowledge dynamic rough recognition theorem and dynamic rough recognition composition principle. Knowledge rough recognition on assistant set is a new method; it has gotten applied in military object recognition, medical diagnosis recognition and etc.
