  public void calcMargins​(BayesNet bayesNet)
                   throws java.lang.Exception

  Calc marginal distributions of nodes in Bayesian network Note that a connected network is assumed. Unconnected networks may give unexpected results.

  Parameters:

  Throws:

  java.lang.Exception

• calcFullMargins

  public void calcFullMargins​(BayesNet bayesNet)
                       throws java.lang.Exception

  Throws:

  java.lang.Exception

• process

  public void process​(boolean[][] bAdjacencyMatrix,
                      BayesNet bayesNet)
               throws java.lang.Exception

  Throws:

• moralize

  public boolean[][] moralize​(BayesNet bayesNet)

  moralize DAG and calculate adjacency matrix representation for a Bayes Network, effecively converting the directed acyclic graph to an undirected graph.

  Parameters:

  bayesNet - : Bayes Network to process

  Returns:

  adjacencies in boolean matrix format

• fillIn

  public boolean[][] fillIn​(int[] order,
                            boolean[][] bAdjacencyMatrix)

  Apply Tarjan and Yannakakis (1984) fill in algorithm for graph triangulation. In reverse order, insert edges between any non-adjacent neighbors that are lower numbered in the ordering. Side effect: input matrix is used as output

  Parameters:

  order - : node ordering

  bAdjacencyMatrix - : boolean matrix representing the graph

  Returns:

  boolean matrix representing the graph with fill ins

• getRevision

  public java.lang.String getRevision()

  Returns the revision string.

  Specified by:

  getRevision in interface RevisionHandler

  Returns:

  the revision

• main

  public static void main​(java.lang.String[] args)
