Detailed Description

template<typename Index_, typename Data_, typename Cluster_, typename Float_, typename Matrix_ = Matrix<Index_, Data_>>
class kmeans::Refine< Index_, Data_, Cluster_, Float_, Matrix_ >

Interface for k-means refinement algorithms.

Template Parameters

Index_	Integer type for the observation indices.
Data_	Numeric type for the data.
Cluster_	Integer type for the cluster assignments.
Float_	Floating-point type for the centroids. This will also be used for any internal distance calculations.
Matrix_	Type for the input data matrix. This should satisfy the Matrix interface.

virtual Details< Index_ > kmeans::Refine< Index_, Data_, Cluster_, Float_, Matrix_ >::run ( const Matrix_ & data, Cluster_ num_centers, Float_ * centers, Cluster_ * clusters ) const

pure virtual

Parameters

	data	A matrix-like object containing per-observation data.
	num_centers	Number of cluster centers.
[in,out]	centers	Pointer to an array of length equal to the product of num_centers and data.num_dimensions(). This contains a column-major matrix where rows correspond to dimensions and columns correspond to cluster centers. On input, each column should contain the initial centroid location for its cluster. On output, each column will contain the final centroid locations for each cluster.
[out]	clusters	Pointer to an array of length equal to the number of observations (from data.num_observations()). On output, this will contain the cluster assignment for each observation.

Returns

centers and clusters are filled, and a Details object is returned containing clustering statistics. If num_centers is greater than data.num_observations(), only the first data.num_observations() columns of the centers array will be filled.
