Graphical Models and Problem Parameters

• What probabilities need I specify to ensure a complete, consistent model given

  • the variables I have identified
  • the dependence and independence relationships I have specified by building a graph structure

• Answer

  • provide an unconditional (prior) probability for every node in the graph with no parents
  • for all remaining, provide a conditional probability table
    • Prob(Child | Parent1, Parent2, Parent3) for all possible combination of Parent1, Parent2, Parent3 values
