ClassDescriptionAbstract class providing common functionality for the original instance implementations.Interface to something that can produce measures other than those calculated by evaluation modules.Interface to something that can aggregate an object of the same type with itself.Class for performing operations on an algebraic vector of floating-point values.Applies all known Javadoc-derived classes to a source file.Class for handling an attribute.This class locates and records the indices of a certain type of attributes, recursively in case of Relational attributes.A Utility class that contains summary information on an the values that appear in a dataset for a particular attribute.Interface to something that can produce predictions in a batch manner when presented with a set of Instances.Class for storing a binary-data-only instance as a sparse vector.A class that describes the capabilites (e.g., handling certain types of attributes, missing values, types of classes, etc.) of a specific classifier.enumeration of all capabilitiesClasses implementing this interface return their capabilities in regards to datasets.Classes implementing this interface make it possible to turn off capabilities checking.Helper class for Capabilities.Implements the Chebyshev distance.Abstract general class for testing in Weka.Simple command line checking of classes that are editable in the GOE.Simple command line checking of classes that implement OptionHandler.Abstract general class for testing schemes in Weka.a class for postprocessing the test-dataA singleton that stores all classes on the classpath.For filtering classes.For filtering classes.This class is used for discovering classes that implement a certain interface or a derived from a certain class.compares two strings.Utility class that can add jar files to the classpath dynamically.Interface to something that can be run from the command line.This subclass of Optimization.java implements conjugate gradient descent rather than BFGS updates, by overriding findArgmin(), with the same tests for convergence, and applies the same line search code.Class implementing some statistical routines for contingency tables.Interface implemented by classes that can produce "shallow" copies of their objects.A class for providing centralized Copyright information.For classes that do not implement the OptionHandler interface and want to provide a custom display string in the GenericObjectEditor, which is more descriptive than the class name.Stores information for date attributes.A helper class for debug output, logging, clocking, etc.A little helper class for clocking and outputting times.contains debug methodsA helper class for logging stuff.This extended Random class enables one to print the generated random numbers etc., before they are returned.A little, simple helper class for logging stuff.A class that can be used for timestamps in files, The toString() method simply returns the associated Date object in a timestamp format.Base class for providing a set of default settings for an application.Class for handling an instance.Class for building and maintaining a dictionary of terms.Interface for any class that can compute and return distances between two instances.Interface to something that can be drawn as a graph.Helper/wrapper class for obtaining an arbitrary enum value from an arbitrary enum type.This class encapsulates a map of all environment and java system properties.Interface for something that can utilize environment variables.Extends Properties to allow the value of a system property (if set) to override that which has been loaded/set.Implementing Euclidean distance (or similarity) function.
One object defines not one distance but the data model in which the distances between objects of that data model can be computed.
Attention: For efficiency reasons the use of consistency checks (like are the data models of the two instances exactly the same), is low.
