Detailed Description

This class UpdateClusterPopulation deletes, adds, and adjusts clusters. This in contrast with UpdateCluster which only adjusts the parameters assigned to a cluster and will leave the number of clusters invariant.

Member Function Documentation

printStatistics()

virtual void UpdateClusterPopulation::printStatistics ( )

pure virtual

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

Implemented in JainNealAlgorithm, TriadicAlgorithm, NealAlgorithm2, and NealAlgorithm8.

update()

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

pure 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

Implemented in JainNealAlgorithm, TriadicAlgorithm, NealAlgorithm2, and NealAlgorithm8.
