Class MPEInference

java.lang.Object

org.linqs.psl.application.inference.InferenceApplication

org.linqs.psl.application.inference.MPEInference

All Implemented Interfaces:

ModelApplication

public class MPEInference
extends InferenceApplication

Infers the most-probable explanation (MPE) state of the RandomVariableAtoms persisted in a Database, according to a Model, given the Database's ObservedAtoms. The set of RandomVariableAtoms is those persisted in the Database when inference() is called. This set must contain all RandomVariableAtoms the Model might access.

Method Detail

completeInitialize

protected void completeInitialize()

Description copied from class: InferenceApplication

Complete the initialization process. All infrastructure will have been constructued, but the ground rule store and term store must be populated.

Specified by:

completeInitialize in class InferenceApplication

inference

public void inference()

Description copied from class: InferenceApplication

Minimizes the total weighted incompatibility of the GroundAtoms in the Database according to the Model and commits the updated truth values back to the Database. The RandomVariableAtoms to be inferred are those persisted in the Database when this method is called. All RandomVariableAtoms which the Model might access must be persisted in the Database.
