Each network is of size N = 4,000, that sampled from the original networks by using the random-walk method (see SI Appendix). The best-performed entries are emphasized in bold. We set $p^H=0.1$ for SPM and for the parameter-dependent Katz index; the present results are obtained under the optimal parameter subject to the highest precision. The results of SBM are not included due to the high computational complexity.
