| Abstract: | The Decision Tree is an important classification algorithm in Data Mining. This article first describes the basic ideas in Decision Tree, then improves ID3 algorithm on its shortcomings of relying much on the quality of data sets, and compares the improved algorithm with the previous one through experiments. The experiments show that the improved algorithm is effective. |
