Embodiment 2

[0075] The experimental results of the ACWGAN-GP algorithm proposed in this application are compared with the results of the other nine algorithms, and the experimental results are shown in Table 1. Observing Table 1, it can be found that ACWGAN-GP is in τ macroacc It performs better on metrics, achieving the best performance on 9 of the 13 public datasets, and the best results in each public dataset are highlighted in bold. The average accuracy of ACWGAN-GP on the 13 sets of data also achieved the best performance, and it was 5.52% higher than the best method among the remaining methods.

[0076]Then the Wilcoxon signed rank test and Friedman test were used to compare different methods. The results of the Wilcoxon signed rank test are shown in Table 2, where the value of R+ represents the rank sum of the ACWGAN-GP method, and the value of R- represents the rank sum of the remaining nine methods. It can be seen from Table 2 that, except for CWGAN-GP, all the other methods ar...
