| 摘 要： | 文理分科是高中生面临的第一次重大选择,选文科还是理科,很多同学感到两头难。针对这种情况,通过对比决策树分类算法中的ID3和C4.5算法,提出了基于影响因子的新的分类算法,构造了"文理分科分类器"。实验证明该方法在文理分科问题上比传统的ID3和C4.5算法有更高的分类精确度,该分类器可以辅助学生和家长进行文理科的选择,降低选择的错误性。

| Abstract: | Arts division is the first important choice faced for high school students,select liberal arts or science,and many students feel two hard.For this situation,by comparing the ID3 and C4.5 algorithm of the decision tree classification algorithm,proposing a new classification algorithm based on impact factors,to construct the departmental system classifier.Experiments show that this method in departmental system issues has higher classification accuracy than the traditional ID3 and C4.5 algorithm,and this clas... |
