Table 5.

Comparison between our model and the method of extending network depth (mean ± STD). The symbol ‘*’ indicates that there is a significant difference between our model and the compared model under the paired t test on the corresponding metric (p-value ≤ 0.05), and the values in parentheses refer to Cohen’s d values
