Detailed Description

This class represents a factored 2D matrix.

Note that we can't use a multi_array since each FactoredMatrix2D may have a different number of BasisMatrices.

Member Function Documentation

getValue() [1/2]

double AIToolbox::Factored::FactoredMatrix2D::getValue	(	const Factors &	space,
		const Factors &	actions,
		const Factors &	value,
		const Factors &	action
	)		const

This function returns the value of the FactoredMatrix2D at the specified point.

Parameters

space	The factor space to use.
actions	The action space to use.
value	The factor to compute the value for.
action	The action to compute the value for.

Returns

The value of the FactoredMatrix2D at the specified point.

getValue() [2/2]

double AIToolbox::Factored::FactoredMatrix2D::getValue	(	const Factors &	space,
		const Factors &	actions,
		const Factors &	value,
		const Factors &	action,
		const Vector &	weights
	)		const

This function returns the value of the FactoredMatrix2D multiplied by the input weights.

Note that if the weights contain an additional element, it will be added to the value as a constant basis.

Parameters

space	The factor space to use.
actions	The action space to use.
value	The factor to compute the value for.
action	The action to compute the value for.
weights	The weights to multiply the bases with, with an optional constant basis.

Returns

The value of the FactoredMatrix2D at the specified point.

operator*=() [1/2]

FactoredMatrix2D& AIToolbox::Factored::FactoredMatrix2D::operator*=

(

const double

v

)

This function multiplies all bases with a scalar.

Parameters

v	The scalar to multiply with.

Returns

A reference to this FactoredMatrix2D.

operator*=() [2/2]

FactoredMatrix2D& AIToolbox::Factored::FactoredMatrix2D::operator*=

(

const Vector &

w

)

This function multiplies each basis function with a weight.

The input Vector must have the same number of elements as the number of bases in this FactoredVector, or one optional more.

Each basis is multiplied by its respective scalar. If an additional weight is present in the input, it is divided by the number of bases and added to each of them. Note that if the FactoredMatrix2D contains duplicate tags this is probably not what you want!!

Parameters

w	The weights to multiply with.

Returns

A reference to this FactoredMatrix2D.
