◆ sample() [1/2]

DiscreteValues gtsam::DiscreteBayesNet::sample ( ) const

do ancestral sampling

Assumes the Bayes net is reverse topologically sorted, i.e. last conditional will be sampled first. If the Bayes net resulted from eliminating a factor graph, this is true for the elimination ordering.

Returns: a sampled value for all variables.

Definition at line 52 of file DiscreteBayesNet.cpp.

◆ sample() [2/2]

DiscreteValues gtsam::DiscreteBayesNet::sample ( DiscreteValues given ) const

do ancestral sampling, given certain variables.

Assumes the Bayes net is reverse topologically sorted and that the Bayes net does not contain any conditionals for the given values.

Returns: given values extended with sampled value for all other variables.
