The output from the inference algorithms depends on the node definitions and the evidence set on nodes in the network. The evidence for discrete nodes is specified by outcome index or outcome identifier. For continuous, the evidence is a number, and related methods have 'cont' in their names (for example, Network.getContEvidence). In dynamic Bayesian networks (DBNs), evidence is specified for a specified time slice. The evidence methods for DBNs have 'temporal' in their names (for example, Network.getTemporalEvidence).
Nodes can become propagated evidence (implied by other evidence set in the network).
Special type of evidence for discrete nodes is virtual evidence, which is a probability distribution over the outcomes of the node.
