Member Function Documentation

virtual CPT* CPT::Clone ( ) const

inlinevirtual

Returns a pointer to a copy of this class.

Implements CPDDiscreteInterface.

References CPT().

double CPT::Get	(	Index	x,
		Index	y
	)		const

inlinevirtual

Returns $ P(x|y) $ .

Implements CPDDiscreteInterface.

References _m_probTable.

const Matrix* CPT::GetMatrixPtr ( ) const

inline

Get a pointer to the CPT.

size_t CPT::nrX ( ) const

inlineprotected

Referenced by Sample().

size_t CPT::nrY ( ) const

inlineprotected

Index CPT::Sample ( Index y ) const

virtual

Returns an (index of a) x drawn according to $ P(x|y) $ .

Implements CPDDiscreteInterface.

References _m_probTable, and nrX().

void CPT::SanityCheck ( ) const

virtual

Implements CPDDiscreteInterface.

References _m_probTable, and Globals::EqualProbability().

void CPT::Set	(	Index	x,
		Index	y,
		double	prob
	)

inlinevirtual

Sets P(x|y)

x, y are indices of the 'state': e.g. x is an index to the x-th element in X (the set of values x can take) taken joint action and resulting successor state. prob is the probability. The order of events is s, ja, s', so is the arg. list

void CPT::SetRandom ( )

This will randomize the CPT.
