Modifier and Type	Method and Description
AbstractFactor	create(List<Integer> vars, List<AbstractFactor> multiplicationPartners) creates a factor, the class of which is dependent on different criteria defined in the concrete subclasses.
static FactorFactory	defaultFactory()
protected boolean	getUseLogScale(AbstractFactor f)
void	setFloatingPointType(Class<?> contentType) sets the floating point precision to use.
void	setReferenceNetwork(BayesNet net)
void	setUseLogScale(boolean useLogScale) using logarithmic values for computation is a lot slower, but also a lot more numerically stable

Method Detail

setFloatingPointType

public void setFloatingPointType(Class<?> contentType)

sets the floating point precision to use.

Parameters:

contentType - possible values: double.class, Double.class, float.class, Float.class

setReferenceNetwork

public void setReferenceNetwork(BayesNet net)

setUseLogScale

public void setUseLogScale(boolean useLogScale)

using logarithmic values for computation is a lot slower, but also a lot more numerically stable

Parameters:

useLogScale - use log scale

create

public AbstractFactor create(List<Integer> vars,
                             List<AbstractFactor> multiplicationPartners)

creates a factor, the class of which is dependent on different criteria defined in the concrete subclasses. The default behavior is to return a DenseFactor.

Parameters:

vars - input vars

multiplicationPartners - multiplication partners

Returns:

the resulting factor

getUseLogScale

protected boolean getUseLogScale(AbstractFactor f)

defaultFactory

public static FactorFactory defaultFactory()
