Class ConfidenceAnalysis

java.lang.Object

edu.umd.cs.psl.application.inference.ConfidenceAnalysis

All Implemented Interfaces:

ModelApplication

public class ConfidenceAnalysis
extends Object
implements ModelApplication

Infers the means and inverse standard deviations 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 #mpeInference() is called. This set must contain all RandomVariableAtoms the Model might access. (DatabasePopulator can help with this.)

Infers the means and inverse standard deviations of the RandomVariableAtoms persisted in a Database, according to a Model, given the Database's ObservedAtoms, sets them as each Atom's truth values and confidence values, and commits them 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.

Returns:

analysis results

Throws:

ClassNotFoundException

IllegalAccessException

InstantiationException
