Infact,ourexperiments are35 designed todemonstrate thatthevGraph frameworkenables community detection andnode representation learning36 to benefit one other, not to prove that it outperforms all existing studies. Therefore, we decided to choose certain37 representativemethods(i.e.,matrixfactorization-based methods,generativemodels,andK-Meansafternodeembed-38 dings) which help validate this point. We will discuss more studies in the revised draft.(2)AboutchoosingK. In39 practice, when the trueK is not given, we can still chooseK according to the performance on validation set (as in40 [14,36]).
