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.
Returns:
Number of points changed (0).
