Class TreeQuery

Static query

• query(network: Network, queryDistributions: IQueryDistributionCollection, evidence: IEvidence, queryOptions: TreeQueryOptions): TreeQueryOutput

• Calculates properties of a Bayesian network or Dynamic Bayesian network when converted to a tree for inference.

  This is done without requiring the memory to actually perform inference, and so can be useful to test whether exact inference is feasible on a network, or determine approximate memory requirements.

  This can be done while taking into account any evidence currently set, and the particular queries that are being requested.

  Parameters

  • network: Network

    The Bayesian network or Dynamic Bayesian network.

  • queryDistributions: IQueryDistributionCollection

    The distributions being queried.

  • evidence: IEvidence

    Any evidence.

  • queryOptions: TreeQueryOptions

    Options which affect how the query is performed.

  Returns TreeQueryOutput

  Information about the tree, such as tree width.
