这是一个由java实现的数据挖掘

2001-03-13 16:52  mhall

	* weka/: classifiers/MultiClassClassifier.java (1.22),
	classifiers/neural/NeuralNetwork.java (1.3),
	core/converters/AbstractLoader.java (1.2),
	core/converters/ArffLoader.java (1.2), core/converters/Loader.java
	(1.2), core/converters/SerializedInstancesLoader.java (1.2),
	filters/Makefile (1.18), gui/GenericObjectEditor.props (1.33): Made
	Weka java 1.1 compatible for the new stable release.

2001-03-12 11:32  eibe

	* weka/classifiers/j48/: BinC45Split.java (1.5),
	C45ModelSelection.java (1.5), C45PruneableClassifierTree.java
	(1.6), C45Split.java (1.5), ClassifierDecList.java (1.4),
	ClassifierSplitModel.java (1.5), ClassifierTree.java (1.11),
	Distribution.java (1.5), J48.java (1.20), MakeDecList.java (1.6):
	Added option for Laplace-corrected probability estimates in J48. 
	Fixed bug that lead to slightly incorrect probability estimates for
	datasets with missing values (if subtree raising occurred).

2001-03-02 16:54  mhall

	* weka/experiment/RemoteExperiment.java (1.8): Updated header docs
	to reflect changes.

2001-03-02 16:53  mhall

	* weka/experiment/remote.policy (1.3): Commented out the lines
	pertaining to example file permissions for codebases from file
	urls.

2001-03-02 16:52  mhall

	* weka/Makefile (1.30): Added lines to the install section to make
	a remoteExperimentServer.jar file containing a remote.policy a copy
	of DatabaseUtils.props and a remoteEngine.jar (which contains only
	those classes needed for deploying remoteEngines).

2001-03-02 09:22  mhall

	* weka/experiment/remote.policy (1.2): Updated security policy with
	new permissions that allow downloading of classes from client
	codebases and reading/writing of properties and reading of files by
	those classes.

2001-03-01 15:44  mhall

	* weka/: experiment/DatabaseUtils.java (1.14), core/Utils.java
	(1.28), gui/GenericObjectEditor.java (1.25): Changed so that
	loading of default properties (Utils.java) from system resource no
	longer throws an exception if the properties file is not found.
	This was causing problems for remote experiment objects when
	classes were being downloaded by rmi from client codebases as
	needed. Changed GenericObjectEditor and DatabaseUtils to throw
	exceptions if no properties are succesfully obtained from anywhere
	(ie, system resource, user home or local dir).

2001-02-28 11:08  mhall

	* weka/experiment/Makefile (1.11): Added TaskStatusInfo.

2001-02-28 11:07  mhall

	* weka/experiment/TaskStatusInfo.java (1.1): Initial import.

2001-02-28 11:06  mhall

	* weka/experiment/: Compute.java (1.3), RemoteEngine.java (1.3),
	RemoteExperiment.java (1.7), RemoteExperimentSubTask.java (1.4),
	Task.java (1.4): RemoteEngines now use a queue to schedule Tasks
	for execution. Also allow clients to query on the status of Tasks.

2001-02-23 16:22  eibe

	* weka/classifiers/Makefile (1.22): Updated to include
	DistributionMetaClassifier

2001-02-19 16:12  mhall

	* weka/experiment/: RemoteExperiment.java (1.6),
	RemoteExperimentSubTask.java (1.3): Modified to allow experiments
	to be split up on the basis of data set or run number.

2001-02-19 16:11  mhall

	* weka/gui/experiment/: DistributeExperimentPanel.java (1.3),
	SetupPanel.java (1.16): Modified to allow user to configure how a
	distributed experiment will be split up.

2001-02-19 11:41  eibe

	* weka/classifiers/Logistic.java (1.11): Logistic regression
	converges more frequently now thanks to changes made by Tony Voyle.

2001-02-18 15:00  mhall

	* weka/gui/experiment/GeneratorPropertyIteratorPanel.java (1.7):
	Now allows listeners to be added. Listener's get notified when
	there is a change of editing status of the panel, ie. enabled,
	disabled.

2001-02-18 14:59  mhall

	* weka/gui/experiment/SetupPanel.java (1.15): Added a panel to
	control how iterations are performed. Data sets can be advanced and
	then custom iterators, or vis versa.

2001-02-18 14:57  mhall

	* weka/experiment/Experiment.java (1.14): Modified to allow
	iteration over data sets then custom iterators or vis versa.

2001-02-13 11:11  mhall

	* weka/gui/: GenericArrayEditor.java (1.10),
	GenericObjectEditor.java (1.24): Fixed bug (in GenericArrayEditor)
	that would cause the Generator properties panel in the Experimenter
	to be disabled yet still display a list from a previous experiment.
	Changed GenericObjectEditor's setObject method	to test for
	equality (compares pointers) before firing a property change event.
	Switching between normal and remote experiments in the Experimenter
	was triggering a property change sequence that would disable the
	generator properties panel. Not an ideal solution, all editable
	objects should implement an equals method. Experimenter still has
	some problems: loading a pre-saved experiment after manually
	configuring the ResultProducer will cause property change events to
	render the generator properties panel disabled (even if generator
	properties are enabled and configured in the saved experiment).

2001-02-12 14:16  mhall

	* weka/classifiers/UserClassifier.java (1.7): Added link to the
	working paper in the class docs.

2001-02-12 10:08  rbk1

	* weka/core/Attribute.java (1.17): Fixed numValues() documentation
	- string attributes don't return 0.

2001-02-08 13:39  eibe

	* weka/classifiers/Makefile (1.21): Forgot to change nn to neural
	in some places.
