为进一步从统计学角度对各个模型性能进行对比，本文对4个算法做Wilco

In order to further compare the performance of each model from a statistical point of view, this paper does Wilcoxon sign test on the four algorithms. If p-value is less than 0.05, it can be considered that CCGOA-KNN is due to other algorithms. Table 2 lists the p-value values ​​obtained by performing statistical tests on the test. From the table, it can be found that the test results obtained by CCGOA-KNN are significantly better than the other four methods.

In order to further compare the performance of each model from a statistical point of view, the Wilcoxon symbol test is done on 4 algorithms. If p-value is less than 0.05, CCGOA-KNN can be considered CCGOA-KNN due to other algorithms. Table 2 lists the p-value values obtained from the statistical test of the experiment, and it can be found from the table that the results obtained by CCGOA-KNN are significantly better than the other 4 methods.

In order to further compare the performance of each model from the perspective of statistics, this paper does Wilcoxon symbol test for four algorithms. If P-value is less than 0.05, ccgoa-knn can be considered as the result of other algorithms. Table 2 lists the p-value values obtained from the statistical test of the test. From the table, it can be found that the test results obtained by ccgoa-knn are significantly superior to the other four methods.<br>
