Method Detail

createInferenceEngine

public Inference createInferenceEngine(Network network)

Uses the factory design pattern to create inference related objects for the Variable elimination algorithm. See InferenceFactory for more details.

Specified by:

createInferenceEngine in interface InferenceFactory

Parameters:

network - The target Bayesian network.

Returns:

The inference algorithm/engine.

createQueryOptions

public QueryOptions createQueryOptions()

Creates a VariableEliminationQueryOptions instance that governs the calculations performed by the VariableEliminationInference.query(com.bayesserver.inference.QueryOptions, com.bayesserver.inference.QueryOutput) method.

Specified by:

createQueryOptions in interface InferenceFactory

Returns:

The options for use with VariableEliminationInference.query(com.bayesserver.inference.QueryOptions, com.bayesserver.inference.QueryOutput).

createQueryOutput

public QueryOutput createQueryOutput()

Creates a VariableEliminationQueryOutput instance that collects information about each query, in addition to the distributions.

The output object can be created once, and reused over many calls to Inference.query(com.bayesserver.inference.QueryOptions, com.bayesserver.inference.QueryOutput).

Specified by:

createQueryOutput in interface InferenceFactory

Returns:

The output instance.
