Abstract: |
The matrix expression of attribute reduction based on information entropy is given.Then a new algorithm of attribute reduction based on information entropy is designed.And the feasibility of algorithm is verified with an example.The algorithm is relatively straightforward,easy to understand,and use less auxiliary space. |
