Interface AssignCluster<D>

All Superinterfaces:

java.io.Serializable

All Known Implementing Classes:

AssignGmm_F64, AssignKMeans_F64

public interface AssignCluster<D>
extends java.io.Serializable

Used to assign a point to set of clusters. Clusters are given labels from 0 to N-1, where N is the number of clusters.

Method Summary

Modifier and Type	Method and Description
int	assign(D point) Assigns the point to cluster which is the best fit.
void	assign(D point, double[] fit) Performs a soft assignment of a point to all the clusters.
AssignCluster<D>	copy() Creates an exact copy of this class.
int	getNumberOfClusters() Total number of clusters.

Method Detail

assign

int assign(D point)

Assigns the point to cluster which is the best fit.

Parameters:

point - Point which is to be assigned

Returns:

Index of the cluster from 0 to N-1

assign

void assign(D point,
            double[] fit)

Performs a soft assignment of a point to all the clusters. Clusters with a better fit will have a larger value in 'fit'. The sum of fit is equal to 1, unless everything is zero. Then it is zero.

Parameters:

point - Point which is to be assigned

fit - Storage for relative fit quality of each cluster. Length must be at least the number of clusters.

getNumberOfClusters

int getNumberOfClusters()

Total number of clusters.

Returns:

The total number of clusters.

copy

AssignCluster<D> copy()

Creates an exact copy of this class.

Returns:

Copy of class
