What is a conditional probability table?

  • A.A table listing every joint probability in the whole network
  • B.A table recording which nodes are conditionally independent of which
  • C.A summary of the observed frequencies collected from the training data
  • D.The distribution of a node given each parent combination

Answer: D

Each node carries a distribution over its own values for every combination of parent values, and those tables together with the structure determine the full joint. The table is local: it never mentions non-parents. A joint listing, an independence catalogue and raw frequency counts are all different objects. Seeing that the network is nothing but structure plus these local tables is what makes its storage saving concrete rather than a slogan.
