LoopyBeliefInferenceFactory

public LoopyBeliefInferenceFactory()

Method Detail

createInferenceEngine

public Inference createInferenceEngine(Network network)

Creates an instance of an inference algorithm, with the [network] as it's target.

Specified by:

createInferenceEngine in interface InferenceFactory

Parameters:

network - The target Bayesian network.

Returns:

The inference algorithm/engine.

createQueryOptions

public QueryOptions createQueryOptions()

Creates options that govern how each query is performed. Each algorithm may provide additional options.

Specified by:

createQueryOptions in interface InferenceFactory

Returns:

The options.

createQueryOutput

public QueryOutput createQueryOutput()

Creates an object that collects information about each query, in addition to the distributions. Each algorithm may provide additional output information.

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.
