ProbEvidenceSampler 

Companion object ProbEvidenceSampler

abstract class ProbEvidenceSampler extends ProbEvidenceAlgorithm with Sampler

Algorithm that computes probability of evidence using forward sampling. The evidence is specified as NamedEvidence. Only the probability of this evidence is computed. Conditions and constraints that are already on elements are considered part of the definition of the model.

Abstract Value Members

The algorithm used to compute the probability of additional evidence, as created by probAdditionalEvidence.

The algorithm used to compute the probability of additional evidence, as created by probAdditionalEvidence. This algorithm can be different to the one defined in this class. (For example, a one-time algorithm can use an anytime algorithm for additional evidence.)

17. def initialize(): Unit

Since probability of evidence algorithms introduce additional evidence (namely, their evidence argument), into an existing universe, a mechanism must be provided for introducing the evidence when the algorithm begins and cleaning it up at the end.

Since probability of evidence algorithms introduce additional evidence (namely, their evidence argument), into an existing universe, a mechanism must be provided for introducing the evidence when the algorithm begins and cleaning it up at the end. This is achieved with the initialize method, called when the algorithm starts, and the cleanUp method, called when the algorithm is killed.
