Constructor Detail

DataDrivenInference

public DataDrivenInference(WorkingMemory wm,
                           XTTModel model,
                           Configuration conf)

The constructor that collect all the required information for the inference process to be executed.

Parameters:

wm - a WorkingMemory element from HeaRT inference engine

model - a XTTModel that will be used to infer data

conf - a Configuration object defining uncertainty handling mechanism, conflict set resolution,

Method Detail

initStackForAttributes

protected java.util.Stack<Table> initStackForAttributes(InferenceAlgorithm.AttributeParameters attributeParameters)

Description copied from class: InferenceAlgorithm

The method creates an initial stack of Tables that should be processed by the InferenceAlgorithm.runRules(Table t) method. This is only an initial state and it can be modified during the inference. However for some inference modes this initial stack will be the final.

Specified by:

initStackForAttributes in class InferenceAlgorithm

Parameters:

attributeParameters - attributes names which values should be obtain in the inference process

Returns:

stack fo tables to be fired. This stack can be later modified during the inference process in InferenceAlgorithm.runRules(Table t) method.

initStackForTables

protected java.util.Stack<Table> initStackForTables(InferenceAlgorithm.TableParameters tableParameters)

Description copied from class: InferenceAlgorithm

The method creates an initial stack of Tables that should be processed by the InferenceAlgorithm.runRules(Table t) method This is only an initial state and it can be modified during the inference. However for some inference modes this initial stack will be the final.

Specified by:

initStackForTables in class InferenceAlgorithm

Parameters:

tableParameters - tables names that are the parameters to the inference engine. This could mean different things in different reasoning modes.

Returns:

stack fo tables to be fired. This stack can be later modified during the inference process in InferenceAlgorithm.runRules(Table t) method.
