One-dimensional analysis of parameters performed in DB2F.

Comparison between the accuracy achieved with the default and the best parameter. The difference between the former and the latter in DB2F was summarized with the average, the standard deviation and the maximum difference. Note that for most of the parameters the average is not significantly greater than zero, suggesting that default parameters provide a good discriminability of the data.对采用默认参数与最优参数时所取得的准确率进行了对比分析。针对DB2F指标下二者的差值，以均值、标准差及最大差值作为统计指标进行了汇总分析。值得注意的是，绝大多数参数对应的差值均值未显著大于零，这表明默认参数能够对数据实现良好的区分能力。
