Detailed Description

Parameters for HAK.

Member Function Documentation

dai::HAK::Properties::DAI_ENUM	(	ClustersType	,
		MIN	,
		BETHE	,
		DELTA	,
		LOOP
	)

Enumeration of possible cluster choices.

The following cluster choices are defined:

• MIN minimal clusters, i.e., one outer region for each maximal factor
• DELTA one outer region for each variable and its Markov blanket
• LOOP one cluster for each loop of length at most Properties::loopdepth, and in addition one cluster for each maximal factor
• BETHE Bethe approximation (one outer region for each maximal factor, inner regions are single variables)

dai::HAK::Properties::DAI_ENUM	(	InitType	,
		UNIFORM	,
		RANDOM
	)

Enumeration of possible message initializations.
