| Abstract: | The rough set theory in view of entropy theory was analyzed, and the concepts in rough set were discussed and some properties of entropy theory in rough set theory were proved. From the analysis, a mapping between entropy theory and rough set theory, and the information foundation to find effective decision rule were constructed. |
