Here we extend their approach by  overlapped clustering, instead of crisp clustering which is used in  Cluster-GCN.  This is achieved by allowing the marginal nodes to contribute to training in more than one cluster.  The evaluation of the proposed method is investigated through the experiments on several benchmark datasets.The experimental results show that the proposed method is more efficient than Cluster-GCN, in average. %U https://jac.ut.ac.ir/article_85195_6bd7afc9f38573934afca1482479dd4d.pdf
