mlpack::kmeans::AllowEmptyClusters::AllowEmptyClusters ( ) [inline]

Default constructor required by EmptyClusterPolicy policy.

Definition at line 39 of file allow_empty_clusters.hpp.

template<typename MatType >

static size_t mlpack::kmeans::AllowEmptyClusters::EmptyCluster	(	const MatType &	,
		const	size_t,
		const MatType &	,
		arma::Col< size_t > &	,
		arma::Col< size_t > &
	)			`[inline, static]`

This function does nothing.

It is called by K-Means when K-Means detects an empty 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.
	centroids	Centroids of each cluster (one per column).
	clusterCounts	Number of points in each cluster.
	assignments	Cluster assignments of each point.
