Gaussian mean field is an important paradigm of cluster-based variational inference, and its cluster selection is critical to the tradeoff between the variational accuracy and the computational complexity of cluster-based variational inference. In this paper, we explore a coupling based cluster selection method for Gaussian mean fields. First, we propose the model coupling and the quasi-coupling concepts on Gaussian Markov random field, and prove the coupling-accuracy theorem for Gaussian mean fields, which regards the quasi-coupling as a cluster selection criterion. Then we design a normalized cluster selection algorithm based on the criterion for Gaussian mean fields. Finally, we design numerical experiments to demonstrate the validity and efficiency of the cluster selection method and algorithm.
