java.lang.Object

gov.sandia.cognition.util.AbstractCloneableSerializable

gov.sandia.cognition.learning.algorithm.clustering.hierarchy.AbstractClusterHierarchyNode<DataType,ClusterType>

gov.sandia.cognition.learning.algorithm.clustering.hierarchy.BinaryClusterHierarchyNode<DataType,ClusterType>

gov.sandia.cognition.learning.algorithm.clustering.AgglomerativeClusterer.HierarchyNode<DataType,ClusterType>

Type Parameters:

DataType - The type of the data being clustered.

ClusterType - The type of the clusters being created.

All Implemented Interfaces:

Cluster<DataType>, ClusterHierarchyNode<DataType,ClusterType>, CloneableSerializable, java.io.Serializable, java.lang.Cloneable

Enclosing class:

AgglomerativeClusterer<DataType,ClusterType extends Cluster<DataType>>

public static class AgglomerativeClusterer.HierarchyNode<DataType,ClusterType extends Cluster<DataType>>
extends BinaryClusterHierarchyNode<DataType,ClusterType>

Holds the hierarchy information for the agglomerative clusterer. It is a binary node that also keeps track of the divergence between children.
