Interface Summary

Interface	Description
Compute	Interface to something that can accept remote connections and execute a task.
InstanceQueryAdapter	An interface implemented by InstanceQuery and any user class that is to be passed as the first argument to InstanceQuery.retrieveInstances(InstanceQueryAdapter, ResultSet).
RemoteExperimentListener	Interface for classes that want to listen for updates on RemoteExperiment progress
ResultListener	Interface for objects able to listen for results obtained by a ResultProducer
ResultProducer	This interface defines the methods required for an object that produces results for different randomizations of a dataset.
SplitEvaluator	Interface to objects able to generate a fixed set of results for a particular split of a dataset.
Task	Interface to something that can be remotely executed as a task.
Tester	Interface for different kinds of Testers in the Experimenter.

Class Summary

Class	Description
AveragingResultProducer	Takes the results from a ResultProducer and submits the average to the result listener.
ClassifierSplitEvaluator	A SplitEvaluator that produces results for a classification scheme on a nominal class attribute.
CostSensitiveClassifierSplitEvaluator	SplitEvaluator that produces results for a classification scheme on a nominal class attribute, including weighted misclassification costs.
CrossValidationResultProducer	Generates for each run, carries out an n-fold cross-validation, using the set SplitEvaluator to generate some results.
CrossValidationSplitResultProducer	Carries out one split of a repeated k-fold cross-validation, using the set SplitEvaluator to generate some results.
CSVResultListener	Takes results from a result producer and assembles them into comma separated value form.
DatabaseResultListener	Takes results from a result producer and sends them to a database.
DatabaseResultProducer	Examines a database and extracts out the results produced by the specified ResultProducer and submits them to the specified ResultListener.
DatabaseUtils	DatabaseUtils provides utility functions for accessing the experiment database.
DensityBasedClustererSplitEvaluator	A SplitEvaluator that produces results for a density based clusterer.
Experiment	Holds all the necessary configuration information for a standard type experiment.
ExplicitTestsetResultProducer	Loads the external test set and calls the appropriate SplitEvaluator to generate some results. The filename of the test set is constructed as follows: <dir> + / + <prefix> + <relation-name> + <suffix> The relation-name can be modified by using the regular expression to replace the matching sub-string with a specified replacement string.
InstanceQuery	Convert the results of a database query into instances.
InstancesResultListener	Outputs the received results in arff format to a Writer.
LearningRateResultProducer	Tells a sub-ResultProducer to reproduce the current run for varying sized subsamples of the dataset.
OutputZipper	OutputZipper writes output to either gzipped files or to a multi entry zip file.
PairedCorrectedTTester	Behaves the same as PairedTTester, only it uses the corrected resampled t-test statistic.
PairedStats	A class for storing stats on a paired comparison (t-test and correlation)
PairedStatsCorrected	A class for storing stats on a paired comparison.
PairedTTester	Calculates T-Test statistics on data stored in a set of instances.
PropertyNode	Stores information on a property of an object: the class of the object with the property; the property descriptor, and the current value.
RandomSplitResultProducer	Generates a single train/test split and calls the appropriate SplitEvaluator to generate some results.
RegressionSplitEvaluator	A SplitEvaluator that produces results for a classification scheme on a numeric class attribute.
RemoteEngine	A general purpose server for executing Task objects sent via RMI.
RemoteExperiment	Holds all the necessary configuration information for a distributed experiment.
RemoteExperimentEvent	Class encapsulating information on progress of a remote experiment
RemoteExperimentSubTask	Class to encapsulate an experiment as a task that can be executed on a remote host.
ResultMatrix	This matrix is a container for the datasets and classifier setups and their statistics.
ResultMatrixCSV	Generates the matrix in CSV ('comma-separated values') format.
ResultMatrixGnuPlot	Generates output for a data and script file for GnuPlot.
ResultMatrixHTML	Generates the matrix output as HTML.
ResultMatrixLatex	Generates the matrix output in LaTeX-syntax.
ResultMatrixPlainText	Generates the output as plain text (for fixed width fonts).
ResultMatrixSignificance	Only outputs the significance indicators.
Stats	A class to store simple statistics.
TaskStatusInfo	A class holding information for tasks being executed on RemoteEngines.
