The problem of learning the structure of a Gaussian graphical model is to infer the graph representing the relationship between random variables of the model from sample. In this paper, we consider the problem whose graphs are restricted to be scale-free, and propose an algorithm based on a Markov Chain Monte Calro (MCMC) method for solving the problem by designing a regularization term for scale-free graphs. Our method is shown to outperform another MCMC method. |
