Package weka.clusterers

Interface Summary
Clusterer Interface for clusterers.
DensityBasedClusterer Interface for clusterers that can estimate the density for a given instance.
NumberOfClustersRequestable Interface to a clusterer that can generate a requested number of clusters
UpdateableClusterer Interface to incremental cluster models that can learn using one instance at a time.
 

Class Summary
AbstractClusterer Abstract clusterer.
AbstractDensityBasedClusterer Abstract clustering model that produces (for each test instance) an estimate of the membership in each cluster (ie.
CheckClusterer Class for examining the capabilities and finding problems with clusterers.
ClusterEvaluation Class for evaluating clustering models.

Valid options are:

-t name of the training file
Specify the training file.

Cobweb Class implementing the Cobweb and Classit clustering algorithms.

Note: the application of node operators (merging, splitting etc.) in terms of ordering and priority differs (and is somewhat ambiguous) between the original Cobweb and Classit papers.
EM Simple EM (expectation maximisation) class.

EM assigns a probability distribution to each instance which indicates the probability of it belonging to each of the clusters.
FarthestFirst Cluster data using the FarthestFirst algorithm.

FilteredClusterer Class for running an arbitrary clusterer on data that has been passed through an arbitrary filter.
HierarchicalClusterer Hierarchical clustering class.
MakeDensityBasedClusterer Class for wrapping a Clusterer to make it return a distribution and density.
RandomizableClusterer Abstract utility class for handling settings common to randomizable clusterers.
RandomizableDensityBasedClusterer Abstract utility class for handling settings common to randomizable clusterers.
RandomizableSingleClustererEnhancer Abstract utility class for handling settings common to randomizable clusterers.
