由java开发的软件包

	RandomSplitResultProducer.java (1.8): Stripped weka.classifiers,
	weka.attributeSelection and weka.filters from file names sent to
	the ouputZipper. Filenames for meta classifers were getting too
	long.

2000-04-05 14:00  mhall

	* weka/experiment/: ClassifierSplitEvaluator.java (1.8),
	RegressionSplitEvaluator.java (1.8): Fixed bug in
	getRawResultOutput.

2000-04-04 17:28  mhall

	* weka/core/Makefile (1.8): Added AdditionalMeasureProducer.java

2000-04-04 17:27  mhall

	* weka/experiment/: ClassifierSplitEvaluator.java (1.7),
	RegressionSplitEvaluator.java (1.7),
	CostSensitiveClassifierSplitEvaluator.java (1.5), Experiment.java
	(1.6): Now looks for and uses the AdditionalMeasureProducer
	interface for handling additional measures rather than
	introspection.

2000-04-04 17:25  mhall

	* weka/core/AdditionalMeasureProducer.java (1.1): Initial import.

2000-04-04 17:23  mhall

	* weka/classifiers/: j48/J48.java (1.16), j48/PART.java (1.11),
	m5/M5Prime.java (1.9), DecisionTable.java (1.14),
	AttributeSelectedClassifier.java (1.3): Now implements
	AdditionalMeasureProducer.

2000-04-04 12:46  mhall

	* weka/attributeSelection/RaceSearch.java (1.3): Added an option to
	produce a ranked list of attributes through the forward racing
	process.

2000-04-04 11:11  trigg

	* weka/experiment/PairedTTester.java (1.9): Extracted out some
	repeated code: now uses Utils.removeSubstring()

2000-04-04 11:10  trigg

	* weka/core/Utils.java (1.20): Added method for removing ocurrences
	of a string from another string.

2000-04-03 16:50  mhall

	* weka/experiment/PairedTTester.java (1.8): Now strips all
	occurances of weka.classifiers, weka.filters and
	weka.attributeSelection out of result set names. Also appends a key
	of result set names to the end of test output so that we can tell
	the difference between long scheme+option names.

2000-04-03 15:36  mhall

	* weka/gui/experiment/ResultsPanel.java (1.18): Replaced the combo
	box for setting the test base with a popup Jlist. Can now see the
	difference between meta schemes with different options :-)

2000-04-03 12:43  mhall

	* weka/experiment/DatabaseResultListener.java (1.5): Fixed quoting
	for the query made in loadCache.

2000-04-03 12:42  mhall

	* weka/experiment/DatabaseUtils.java (1.10): If the driver is
	InstantDB strings will be stored as TEXT rather than LONGVARBINARY.
	 This is because InstantDB tries to interpret numeric data that is
	stored to LONGVARBINARY (making it impossible to match Run and Fold
	fields) whereas everything is treated as a string when stored to
	TEXT.

2000-03-31 12:02  mhall

	* weka/gui/treevisualizer/TreeVisualizer.java (1.3): Changed so it
	imports correctly for visualize stuff.

	imports weka.gui.visualize.

2000-03-31 11:53  mhall

	* weka/gui/visualize/: VisualizePanel.java (1.2), Plot2D.java
	(1.2): Fixed bug that was not resetting x and y indexes to 0 when
	new master plot was set.

2000-03-31 10:48  mhall

	* weka/classifiers/UserClassifier.java (1.4): Modified to work with

	of the most current run of attribute selection.

2000-03-31 09:54  mhall

	* weka/filters/AttributeFilter.java (1.8): Fixed inputFormat so
	that attributes are copied rather than just a reference to them.

2000-03-25 09:40  eibe

	* weka/gui/GenericObjectEditor.props (1.16): Added props for
	NumericToBinaryFilter.java

2000-03-25 09:39  eibe

	options for non-random splits with a fixed number of instances.

2000-03-25 09:38  eibe

	InfoGainAttributeEval.java (1.8), PrincipalComponents.java (1.10),
	Ranker.java (1.14), ReliefFAttributeEval.java (1.10): Got rid of

2000-03-25 09:37  eibe

	* weka/classifiers/: SMO.java (1.14), ThresholdSelector.java (1.4):
	- SMO now does something sensible if the dataset contains only
	instances of one class.  - Fixed bug in ThresholdSelector (occured
	if used with hold-out set).

2000-03-25 09:35  eibe

	* weka/core/: Utils.java (stable-3-0-patches.3), Utils.java (1.19):
	Utils.sort() for doubles is no longer "stable" and no longer uses
	"safe" floating-point comparisons (with an epsilon). This might
	slightly alter the results for some datasets if the learning scheme
	involves sorting (eg. J48, IBk, etc.)

2000-03-25 01:49  trigg

	* weka/classifiers/evaluation/EvaluationUtils.java (1.2): Better
	arrangement and new methods.

	PrincipalComponents.java (1.9), ReliefFAttributeEval.java (1.8): -
	Optimized InfoGainAttributeEval for sparse data.  - Replaced
	Utils.sort() with Utils.sortUnsafe()

2000-03-21 11:37  mhall

	* weka/attributeSelection/: AttributeSelection.java (1.17),
	RankedOutputSearch.java (1.4), ForwardSelection.java (1.9),
	Ranker.java (1.13): Modified to allow the number of attributes to
	be retained to be specified. Number to retain (if not specified)
	can be determined from a threshold.

2000-03-17 16:26  trigg

	* weka/Makefile (1.25): Makefile creates doc directories if they do
	not already exist.  Install location is configurable via
	command-line.  Removed a reference to SimpleGUI that's no longer
	relevant.

2000-03-17 13:31  eibe

	* weka/experiment/ClassifierSplitEvaluator.java (1.6): Index from
	command line now starts from 1.

	command line now starts from 1.

2000-03-13 14:55  mhall

	* weka/gui/experiment/: SetupPanel.java (1.11), RunPanel.java
	(1.9): Added a couple of printStackTraces to aid debugging.

2000-03-13 10:31  trigg

	* weka/core/Utils.java (1.18): Changed some unconventional code.

2000-03-12 04:50  eibe

	* weka/classifiers/j48/: MakeDecList.java (stable-3-0-patches.1),
	MakeDecList.java (1.4): MakeDecList wasn't serializable.

2000-03-10 13:42  mhall

	* weka/experiment/InstanceQuery.java (1.7): Made binary types map
	to nominal attributes.

2000-03-10 12:09  mhall

	* weka/attributeSelection/CfsSubsetEval.java (1.9): Delete
	instances with missing class.

2000-03-10 10:33  mhall

	* weka/attributeSelection/RaceSearch.java (1.2): Instances with
	missing class values are now removed from the training data.

2000-03-09 11:23  eibe

	* weka/filters/Filter.java (stable-3-0-patches.2):
	setOutputFormat() in Filter was broken for null arguments.

2000-03-09 11:18  eibe

	broken for null arguments.

2000-03-09 11:08  eibe

	methods.

	which initial key selection is generated.

2000-03-09 11:05  eibe

	* weka/experiment/DatabaseResultProducer.java (1.9):
	backslashquoting in relation name. Long strings in database.

2000-03-09 11:04  eibe

	* weka/experiment/: AveragingResultProducer.java (1.9),
	CrossValidationResultProducer.java (1.6),
	RandomSplitResultProducer.java (1.6), DatabaseUtils.java (1.9):
	Backslashquoting in relation name. Long strings in database.

2000-03-09 05:14  eibe

	* weka/: classifiers/Evaluation.java, clusterers/Cobweb.java,
	filters/Filter.java (stable-3-0-patches.[3,2,1]): 1.
	Evaluation.java: Fixed bug that prevented loading of classifiers
	that require scheme-specific options to be set.  2. Cobweb.java:
	Made inner class CTree serializable so that Cobweb becomes
	serializable.  3. Filter.java: Fixed "memory leak" caused by
	setOutputFormat().

2000-03-09 04:26  eibe

	* weka/classifiers/Evaluation.java (1.31): Scheme-specific options
	don't need to be set for serialized objects that are loaded.

	* weka/clusterers/Cobweb.java (1.7): Made inner class CTree
	serializable.

2000-03-08 15:59  mhall

	* weka/gui/experiment/ResultsPanel.java (1.16): Removed code that
	truncated testBase combo box strings to 20 characters. This was
	making it imposible to differentiate between the same scheme
	(longer than 20 chars) but with different options.

2000-03-08 14:33  mhall

	* weka/gui/explorer/ClassifierPanel.java (1.29): Fixed bug that had
	the tree visualizer displaying the tree for the last fold of a
	k-fold xval instead of for the full training data.

2000-03-08 09:58  eibe

	* weka/gui/experiment/DatasetListPanel.java (1.8): Fixed a few bugs
	related to the "delete" button.

2000-03-08 05:37  eibe

	* weka/filters/Filter.java (1.8): m_OutputFormat kept references to
	all the instances around -> changed setOutputFormat().
