【Abstract】Aiming at the space-time problem during the process of which reduct is figured out by discernibility matrix in rough sets, the principle
and algorithm of discernibility matrix time-consuming calculating are raised, which includes two time-consuming periods calculation and result
reliability verification. The data processing time-consumed by discernibility of matrix is predicted, and the feasibility of data mining experiment is
forecasted.
【Key words】discernibility matrix; time-consuming; calculation
