java.lang.Object
  cc.mallet.grmm.inference.gbp.ClusterVariationalRegionGenerator.ByFactorRegionComputer

All Implemented Interfaces:

ClusterVariationalRegionGenerator.BaseRegionComputer

Enclosing class:

ClusterVariationalRegionGenerator

public static class ClusterVariationalRegionGenerator.ByFactorRegionComputer
extends java.lang.Object
implements ClusterVariationalRegionGenerator.BaseRegionComputer

Region computer where each top-level region consists of a single factor node. If the model is pairwise, this is equivalent to using the Bethe free energy.
