public RCBodyC

HashC> examples;

Map decisions to examples.

HistogramC> histogram;

Frequency of occurance.

DecisionExamplesBodyC()

Default constructor.

DecisionExamplesBodyC(const DataSet2C<SampleStateC,SampleLiteralC> & data)

Construct from a dataset.

void Dump(ostream & out) const

Dump examples to a stream.

bool AddExample(const StateC & state,const LiteralC & decision)

Add an example to the node.
Return's true if example is a new one.

bool RemoveExamples(DecisionExamplesC & examples)

Remove examples from this node.

UIntT Frequency(const Tuple2C<StateC,LiteralC> & inst) const

Find the frequency of an example state and decision.

HashC<LiteralC,HSetC<StateC>> & Examples()

Access examples table, mapping decisions to examples.

const HashC<LiteralC,HSetC<StateC>> & Examples() const

Access examples table, mapping decisions to examples.

HistogramC<Tuple2C<StateC,LiteralC>> & Histogram()

Access frequency table.

RealT DecisionInformation()

Get an estimate of the information in decisions.

bool Seperate(const LiteralC & test,DecisionExamplesC & ttrue,DecisionExamplesC & tfalse) const

Split this set into to, ones where the test is true (ttrue) and ones where its false (tfalse).

UIntT Decisions() const

Get the number of different decisions represented.

DListC<LiteralC> ListDecisions() const

Make a list of decisions.

LiteralC ProbableDecision() const

Get the most likely decision given the examples.

UIntT References() const

Access count of handles open to this object.

RCBodyC & Copy() const

Make copy of body.
This should be provided in derived classes. this funtion will issue an assertion failure if called.

RCBodyC & DeepCopy(UIntT levels = ((UIntT))) const

Make a deep copy of body.
This should be provided in derived classes. this funtion will issue an assertion failure if called.

void IncRefCounter()

Increment reference counter.

bool DecRefCounter()

Decrement reference counter.
