Method Detail

getMonitoredDistribution

public Distribution getMonitoredDistribution(Node node)

Gets a copy of the current distribution assigned to the [node].

Parameters:

node - The node.

Returns:

A copy of the current node distribution.

getMonitoredDistribution

public Distribution getMonitoredDistribution(Node node,
                                             Integer order)

Gets a copy of the current distribution assigned to the [node] at the requested order.

Parameters:

order - The order of the distribution to retrieve. For temporal nodes that may have more than one distribution.

node - The node.

Returns:

A copy of the current node distribution at a specific order.

getMonitoredDistribution

public Distribution getMonitoredDistribution(Node node,
                                             NodeDistributionKey key)

Gets a copy of the current distribution assigned to the [node] at the requested order.

Parameters:

key - The order/related node of the distribution to retrieve. For temporal nodes / noisy nodes that may have more than one distribution.

node - The node.

Returns:

A copy of the current node distribution at a specific order.

getLogLikelihood

public Double getLogLikelihood()

Gets the current log likelihood value, if calculated

This value is only calculated if ParameterLearningOptions.getMonitorLogLikelihood() is true, as it can be expensive to calculate.

For more information about the log likelihood statistic see ParameterLearningOutput.getLogLikelihood().

Returns:

The log likelihood.

getDelta

public Double getDelta()

Gets the relative change in parameters used to determine convergence. See ParameterLearningOptions.getTolerance() for more information about convergence.

getIterationCount

public int getIterationCount()

Gets the current iteration count.

Returns:

The iteration count.
