Influence Diagram
An influence diagram (ID) (also called a relevance diagram, decision diagram or a decision network) is a compact graphical and mathematical representation of a decision situation. It is a generalization of a Bayesian network, in which not only probabilistic inference problems but also decision making problems (following maximum expected utility criterion) can be modeled and solved.
ID was first developed in mid-1970s within the decision analysis community with an intuitive semantic that is easy to understand. It is now adopted widely and becoming an alternative to decision tree which typically suffers from exponential growth in number of branches with each variable modeled. ID is directly applicable in team decision analysis, since it allows incomplete sharing of information among team members to be modeled and solved explicitly. Extension of ID also find its use in game theory as an alternative representation of game tree.

Famous quotes containing the words influence and/or diagram:
“Important as fathers are, their influence on children shouldn’t be exaggerated just because they were ignored so long. There is no evidence that there is something especially good about fathers as caretakers. There are no areas where it can be said that fathers must do certain things in order to achieve certain outcomes in children. The same goes for mothers.”
—Michael Lamb (late–20th century)
“If a fish is the movement of water embodied, given shape, then cat is a diagram and pattern of subtle air.”
—Doris Lessing (b. 1919)
