| Abstract: | To dig useful information from database,and get the easy using rules from difficult understand pure data,then offer future decision information according to the rules obtained in the system.Based on the rough set theory and rules extraction algorithm,an integrated algorithm is proposed.Using rough set theory the redundant attribute can be reduced,and then the efficient rules are obtained according to the rules extraction algorithm.The data in agricultural fields is analyzed by this algorithm and effective rules are obtained.The analysis in theory and the applications show that it is not only effective but also feasible.The algorithm can be widely used in all kinds of large databases,from which the effective rules can be obtained.Then the history's data can serve the future decision-making. |
| Keywords: | rough set theory information quantity reduction of attribute value reduction |
