Cluster variation method in statistical physics and probabilistic graphical models
Cluster variation method in statistical physics and probabilistic graphical models
The cluster variation method (CVM) is a hierarchy of approximate variational techniques for discrete (Ising-like) models in equilibrium statistical mechanics, improving on the mean-field approximation and the BetheāPeierls approximation, which can be regarded as the lowest level of the CVM. In recent years it has been applied both in statistical ā¦
