	GenericObjectEditor.props and related classes.

2000-03-08 04:55  eibe

	* weka/classifiers/ThresholdSelector.java (1.2): Changed
	setClassifier() getClassifier() into setDistributionClassifier()
	and getDistributionClassifier().

2000-03-07 12:19  eibe

	* weka/classifiers/Evaluation.java (1.30): Added some more IR
	statistics.

2000-03-07 12:19  eibe

	* weka/experiment/RegressionSplitEvaluator.java (1.6): Fixed small
	bug concerning UID for ZeroR.

2000-03-07 12:18  eibe

	* weka/experiment/ClassifierSplitEvaluator.java (1.5): Added IR
	statistics.

2000-03-07 09:20  eibe

	* weka/experiment/DatabaseUtils.java (1.8): 1. Replaced "SELECT
	RUN" by "SELECT KeyRun" 2. Replaced AUTO INCREMENT by workaround 3.
	Added hack for MySQL (doesn't support transactions) 4. Changed
	output of double values like 2.0e7 to 2.0e+7 (for MySQL)

2000-03-04 12:13  eibe

	* weka/experiment/PairedTTester.java (1.7): Modified to allow for
	multiple fields to determine "dataset"/row keys.

2000-03-04 12:12  eibe

	* weka/gui/experiment/ResultsPanel.java (1.15): Modified
	ResultsPanel to allow for multiple fields to determine
	"dataset"/row keys.

2000-03-03 07:02  trigg

	* weka/classifiers/SMO.java (1.13): Fix from Stu for when key
	overflows.

2000-03-03 04:33  eibe

	* weka/core/Utils.java (1.16): Added unstable sort method for
	arrays of doubles that does not use safe floating point
	comparisons.

2000-03-02 20:53  trigg

	* weka/filters/NominalToBinaryFilter.java (1.10): Stu spotted this
	hogging huge amounts of memory. Moved the offending member variable
	into the only method it was really used in so the memory gets freed
	after the method returns.

2000-03-02 16:17  trigg

	* weka/core/FastVector.java (1.5): Changed insertElementAt and
	removeElementAt to use built-in ability of System.arraycopy to
	handle source and dest in the same array. Should give speedups due
	to less {array copying, array bounds checking}.

2000-03-02 16:15  trigg

	* weka/classifiers/MultiClassClassifier.java (1.8): Now handles the
	case where not all class values declared in the header appear in
	the (training) data. E.g: iris dataset with setosas removed.

	* weka/classifiers/SMO.java (1.12): Fixed bug in new version of SMO
	that lead to problems on pathological datasets. Got rid of

	* weka/classifiers/ThresholdSelector.java (1.1): Added.

2000-02-29 16:32  trigg

	* weka/classifiers/evaluation/ThresholdCurve.java (1.3): Took out
	debugging output to make it temporarily usable :-).

2000-02-29 16:20  trigg

	* weka/core/FastVector.java (1.4): Fixed two bugs - one in the new
	appendElements method, and one in setCapacity that would throw
	ArrayIndexOutOfBoundsException when setCapacity was used to
	increase the vector size (jeez, how long has that been there :-)).

2000-02-26 12:13  eibe

	* weka/classifiers/IBk.java (1.14): Made IBk faster for sparse
	data. Added option to turn off normalization.

2000-02-25 17:12  mhall

	* weka/classifiers/UserClassifier.java (1.3): Now has a sensible
	toString method. Also outputs any classifiers that the user has
	opted employ at leaves.

2000-02-25 17:06  mhall

	* weka/gui/experiment/ResultsPanel.java (1.14): Changed to reflect
	the renaming of getInstances to retrieveInstances in InstanceQuery.

2000-02-25 17:05  mhall

	* weka/gui/explorer/PreprocessPanel.java (1.16): Now uses the
	generic object editor to configure InstanceQuery for querying a
	database.

2000-02-25 17:04  mhall

	* weka/gui/GenericObjectEditor.java (1.16): For specific classes
	(not mentioned in the props file) the combo box is now removed from
	the editor.

2000-02-25 17:00  mhall

	* weka/experiment/InstanceQuery.java (1.6): Added option handling.
	Changed getInstances to retrieveInstances.

2000-02-25 15:53  trigg

	* weka/classifiers/evaluation/: EvaluationUtils.java (1.1),
	Makefile (1.2), MarginCurve.java (1.1), NominalPrediction.java
	(1.1), ThresholdCurve.java (1.2), TwoClassStats.java (1.1):
	Rearrangement and added margin distribution calculation.

2000-02-25 15:51  trigg

	* weka/core/FastVector.java (1.3): Added a couple of utility
	methods.

2000-02-25 13:53  mhall

	* weka/filters/AttributeSelectionFilter.java (1.14): Modified to
	reflect changes to AttributeTransformer

2000-02-25 13:52  mhall

	* weka/attributeSelection/PrincipalComponents.java (1.8): Tidied
	up. Now works properly with the AttributeSelectionFilter.

2000-02-25 13:51  mhall

	* weka/attributeSelection/AttributeTransformer.java (1.3): Changed
	to be an interface rather than extending AttributeEvaluator

2000-02-25 12:41  eibe

	* weka/filters/ReplaceMissingValuesFilter.java (1.6): Made it
	faster for sparse data.

2000-02-25 10:20  mhall

	* weka/classifiers/j48/Stats.java (stable-3-0-patches.1): Fixed bug
	that caused decision trees to be pruned incorrectly if pruning
	parameter was changed and the VM not restarted.

2000-02-25 09:51  eibe

	* weka/classifiers/j48/Stats.java (1.3): Changing the pruning
	parameter C for J48 after a decision tree has been built causes
	subsequently generated decision trees to be pruned incorrectly if
	the virtual machine is not restarted (ie. changing the pruning
	parameter in the explorer/experimenter/"your own Java program"
	doesn't work properly once one decision tree has been built). 
	Changing the pruning parameter at the command line works fine.
	
	Fixed.

2000-02-24 17:07  mhall

	* weka/gui/explorer/AttributeSelectionPanel.java (1.15): Changed to
	reflect the renaming of a couple of methods in
	AttributeTransformer.

2000-02-24 17:07  mhall

	* weka/attributeSelection/PrincipalComponents.java (1.7): Added the
	ability to perform dimensionality reduction to PrincipalComponents
	itself rather than having to set a threshold in the Ranker search.
	Also (as a consequence) was able to add the ability to transform
	back to the original space from the PC space (this allows a groovy
	kind of attribute noise filtering when some of the worst PCs are
	eliminated).

2000-02-24 17:04  mhall

	* weka/attributeSelection/: AttributeSelection.java (1.15),
	AttributeTransformer.java (1.2), Ranker.java (1.12): Changed took
	the "get" out of getTransformedHeader and getTransformedData.

2000-02-24 13:41  eibe

	* weka/classifiers/Evaluation.java (1.29): Got rid of test for
	StringAttributes in evaluateModel and evaluateModelOnce.

2000-02-24 13:40  eibe

	* weka/core/Instances.java (1.18): Buffering to speed up input of
	sparse instances.

2000-02-24 10:53  mhall

	* weka/attributeSelection/: BestFirst.java (stable-3-0-patches.1),
	BestFirst.java (1.16): evaluation counter now gets reset properly
	for subsequent calls to search :)

	classifiers/CheckClassifier.java (1.10),
