| Abstract: | Introducing the basis theory of Rough Set,the present paper probes into the approach to the reduction of property and its value by employing the theory of Rough Set in the data pre-processing,and reduction algorism with a computer.By giving examples,the paper illustrates that employing the theory of Rough Set in data pre-processing is a very effective way of simplification and of extracting minimum strategic algorism. |
