| Abstract: | Based on classification and discussion of current discretization algorithms,the theoretical basis and accomplishment steps of discretization algorithm using information entropy were analyzed in details,and applications of the algorithm in different sample sets of the same attribute were presented.The experimental results show that the algorithm has sensitivity to some attributes and can affect the decision ability of the system when chosen these attributes. |
