Member Function Documentation

eraseAllEvidence()

template<typename GUM_SCALAR >

virtual void gum::IInfluenceDiagramInference< GUM_SCALAR >::eraseAllEvidence ( )

pure virtual

Remove all evidence from the graph.

Implemented in gum::InfluenceDiagramInference< GUM_SCALAR >.

eraseEvidence()

template<typename GUM_SCALAR >

virtual void gum::IInfluenceDiagramInference< GUM_SCALAR >::eraseEvidence ( const Potential< GUM_SCALAR > *  evidence )

pure virtual

Remove a given evidence from the graph.

Implemented in gum::InfluenceDiagramInference< GUM_SCALAR >.

getBestDecisionChoice()

template<typename GUM_SCALAR >

virtual Idx gum::IInfluenceDiagramInference< GUM_SCALAR >::getBestDecisionChoice ( NodeId  decisionId )

pure virtual

Returns best choice for decision variable given in parameter ( based upon MEU criteria )

Parameters

decisionId

the id of the decision variable

Exceptions

OperationNotAllowed	if no inference have yet been made
InvalidNode	if node given in parmaeter is not a decision node

Implemented in gum::InfluenceDiagramInference< GUM_SCALAR >.

getMEU()

template<typename GUM_SCALAR >

virtual GUM_SCALAR gum::IInfluenceDiagramInference< GUM_SCALAR >::getMEU ( )

pure virtual

Returns maximum expected utility obtained from inference.

Exceptions

OperationNotAllowed

if no inference have yet been made

Implemented in gum::InfluenceDiagramInference< GUM_SCALAR >.

influenceDiagram()

template<typename GUM_SCALAR >

const InfluenceDiagram< GUM_SCALAR >& gum::IInfluenceDiagramInference< GUM_SCALAR >::influenceDiagram

(

)

const

Returns a constant reference over the InfluenceDiagram on which this class work.

insertEvidence()

template<typename GUM_SCALAR >

virtual void gum::IInfluenceDiagramInference< GUM_SCALAR >::insertEvidence ( const List< const Potential< GUM_SCALAR > * > &  evidenceList )

pure virtual

Insert new evidence in the graph.

Warning

if an evidence already w.r.t. a given node and a new evidence w.r.t. this node is onserted, the old evidence is removed.

Exceptions

OperationNotAllowed

Raised if an evidence is over more than one variable.

Implemented in gum::InfluenceDiagramInference< GUM_SCALAR >.

makeInference()

template<typename GUM_SCALAR >

virtual void gum::IInfluenceDiagramInference< GUM_SCALAR >::makeInference ( )

pure virtual

Makes the inference.

Implemented in gum::InfluenceDiagramInference< GUM_SCALAR >.

Member Data Documentation

__infDiag
