Node
The
nodes
are one of the basics in constructing a Hugin
Bbn
or
influence diagram
. Currently, Hugin has four types of nodes different in their look and semantics.
Discrete Chance Nodes
- represent random variables with a discrete finite state space.
Continuous Chance Nodes
- represent random variables with a continuous infinite satet space having a
Gaussian normal distribution
.
Decision Nodes
- represent decisions or actions with a discrete state space.
Utility Nodes
- represent the utility function one or more decisions are to be compared on.
The graph of a Bbn/influence diagram consist of the nodes and the
links
.
