test.updated.bn | R Documentation |
BN
is present in an InferenceEngine
.Check if an InferenceEngine actually contains an updated network, in order to provide the chance of
a fallback and use the original network if no belief propagation has been performed.
An InferenceEngine
built specifying a set of interventions will contain
an updated BN
with altered structure and no conditional probability tables
(unless they are computed by a belief propagation operation.)

TRUE
if an updated network is contained in the InferenceEngine, FALSE
otherwise.
