| 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. |
| Keywords: | discernibility matrix time-consuming calculation |
