Description

Interface Summary

Arithmetic<N extends Number>	An interface to define requirements for a number to perform arithmetic operations.
DatabaseObject	A DatabaseObject should provide handling of a database ID.
DatabaseObjectGroup	Interface for a collection of database references (IDs).
FeatureVector<V extends FeatureVector<V,D>,D>	Generic FeatureVector class that can contain any type of data (i.e. numerical or categorical attributes).
NumberVector<V extends NumberVector<V,N>,N extends Number>	Interface NumberVector defines the methods that should be implemented by any Object that is element of a real vector space of type N.

Class Summary

AbstractDatabaseObject	Abstract super class for all database objects.
AbstractNumberVector<V extends AbstractNumberVector<V,N>,N extends Number>	AbstractNumberVector is an abstract implementation of FeatureVector.
Bit	Provides a bit number.
BitVector	Provides a BitVector wrapping a BitSet.
ClassLabel	A ClassLabel to identify a certain class of objects that is to discern from other classes by a classifier.
Clustering<M extends Model>	Result class for clusterings.
DatabaseObjectGroupArray	Array backed DatabaseObjectGroup.
DatabaseObjectGroupCollection<C extends Collection<Integer>>	Collection-backed group of database object (references)
DoubleVector	A DoubleVector is to store real values approximately as double values.
ExternalObject	Provides an id referencing an external data object.
FloatVector	A FloatVector is to store real values approximately as float values.
HierarchicalClassLabel	A HierarchicalClassLabel is a ClassLabel to reflect a hierarchical structure of classes.
Interval	Represents an interval in a certain dimension of the data space.
KNNList<D extends Distance<D>>	A wrapper class for storing the k most similar comparable objects.
MultiInstanceObject<O extends DatabaseObject>	MultiInstanceObject represents a collection of several DatabaseObjects of an equal type.
MultiRepresentedObject<O extends DatabaseObject>	MultiRepresentedObject represents a collection of several DatabaseObjects of a same superclass.
ParameterizationFunction	A parameterization function describes all lines in a d-dimensional feature space intersecting in one point p.
RationalNumber	RationalNumber represents rational numbers in arbitrary precision.
SimpleClassLabel	A simple class label casting a String as it is as label.
SparseFloatVector	A SparseFloatVector is to store real values approximately as float values.
Subspace<V extends FeatureVector<V,?>>	Represents a subspace of the original data space.
Subspace.DimensionComparator	A comparator for subspaces based on their involved dimensions.
VectorUtil	Utility functions for use with vectors.

Enum Summary
