Detailed Description

Policy which allows K-Means to "kill" empty clusters without any error being reported.

This means the centroids will be filled with DBL_MAX.

inlinestatic

This function sets an empty cluster found during k-means to all DBL_MAX (i.e.

an invalid "dead" cluster).

Template Parameters

MatType Type of data (arma::mat or arma::spmat).

Parameters

data	Dataset on which clustering is being performed.
emptyCluster	Index of cluster which is empty.
oldCentroids	Centroids of each cluster (one per column) at the start of the iteration.
newCentroids	Centroids of each cluster (one per column) at the end of the iteration.
clusterCounts	Number of points in each cluster.
assignments	Cluster assignments of each point.
iteration	Number of iteration.

template<typename Archive >

void mlpack::kmeans::KillEmptyClusters::Serialize	(	Archive &	,
		const unsigned	int
	)

inline
