| 摘 要： | 文章基于UCI数据库中10个常用的数据集对用于算法性能对照时五种交叉验证检验方法的可重复度量进行了比较研究，实验结果表明K折交叉验证（K=2，5，10）t检验随着折数的增大可重复性增大，在相同的计算复杂度下5×2交叉验证F检验和10折交叉验证t检验在大多数情形下有比5×2交叉验证t检验更高的可重复性．

| Abstract: | To studys the replicability of five cross-validated tests used for comparing the performances of algorithms on 10 commonly used datesets of UCI repository. The experimental results show that the replicability of K-fold（K = 2,5,10） cross-validated t test increses with the fold K. And with the same computation complexity, 5 × 2 cross-validated Fand 10-fold cross-vali-dated ttests have more higher replicability than 5×2 cross-validatedttest＇s in majority of cases. |
