Clustering complex networks with the prior based on degree distribution
Naoyuki Harada, Ichiro Takeuchi (NIT), Ryohei Nakano (Chubu Univ.) NC2008-73
Abstract (in Japanese) (See Japanese page) 
(in English) Newman et al. proposed a graph clustering method based on a robabilistic mixture model with only the general assumption that a group of nodes is regarded as a class when the nodes have a similar connection pattern.
Kuwata et al. recently applied a nonparametric Bayesian framework for Newman’s method and it enables us to cluster a graph without knowing the true number of classes in advance.
In this report, we propose a new method that can incorporate the information of the degree distribution of networks as priors.
We show the effectiveness of our method through experiments using both artificial and real data.
