Detailed Description

This class JainNealAlgorithm updates the cluster population assuming a dirichlet process as nonparametric prior.

Constructor & Destructor Documentation

JainNealAlgorithm::JainNealAlgorithm	(	random_engine_t &	generator,
		distribution_t &	likelihood,
		dirichlet_process &	nonparametrics
	)

Construct update method for cluster population.

Parameters

[in]	generator	Random generator
[in]	likelihood	Likelihood function to be used in update()
[in]	nonparametrics	Sufficient statistics of the nonparametric prior (e.g. Dirichlet)

JainNealAlgorithm::~JainNealAlgorithm ( )

void JainNealAlgorithm::printStatistics ( )

virtual

MCMC statistics. How many times are steps rejected, etc.

void JainNealAlgorithm::update	(	membertrix &	cluster_matrix,
		const data_ids_t &	data_ids
	)

virtual

Update the cluster population. The observation has to be deleted beforehand.

Parameters

[in,out]	cluster_matrix	Cluster-observation membership matrix
[in]	data_ids	Observations to be considered for existing and new cluster
