Class DisjunctiveCauseInferenceFactory

java.lang.Object

com.bayesserver.causal.DisjunctiveCauseInferenceFactory

All Implemented Interfaces:

InferenceFactory

public final class DisjunctiveCauseInferenceFactory
extends Object
implements InferenceFactory

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

Constructor Detail

DisjunctiveCauseInferenceFactory

public DisjunctiveCauseInferenceFactory()

Initializes a new instance of the DisjunctiveCauseInferenceFactory class.

DisjunctiveCauseInferenceFactory

public DisjunctiveCauseInferenceFactory(QueryLifecycle queryLifecycle)

Initializes a new instance of the DisjunctiveCauseInferenceFactory class, with an optional lifecycle instance.

Parameters:

queryLifecycle - Lifecycle instance to hook up to query events. Can be null.

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.

getQueryLifecycle

public QueryLifecycle getQueryLifecycle()

Gets a query lifecycle instance. Can be null. This can be used to set the 'Causes of treatments or outcomes' dynamically for each query, e.g. when using the optimizer algorithm.

setQueryLifecycle

public void setQueryLifecycle(QueryLifecycle value)

Sets a query lifecycle instance. Can be null. This can be used to set the 'Causes of treatments or outcomes' dynamically for each query, e.g. when using the optimizer algorithm.

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.
