	(1.2), BayesNetB2.java (1.2), DiscreteEstimatorBayes.java (1.2),
	ParentSet.java (1.2), Scoreable.java (1.2): Set indentation to two
	spaces and made the scoreType property of BayesNet more GUI

	(1.1), BayesNetB2.java (1.1), DiscreteEstimatorBayes.java (1.1):
	Initial import.

2001-10-18 17:30  mhall

	options when a lone '-' is encountered.

2001-10-10 14:36  mhall

	* weka/clusterers/Cobweb.java (1.13): Improved the category utility
	computation for the split operation.

2001-10-04 13:43  trigg

	* weka/filters/SpreadSubsampleFilter.java (1.10): Quieter
	operation.

2001-10-04 13:43  trigg

	* weka/filters/FirstOrderFilter.java (1.15): Fixed for date
	attributes.

2001-10-04 13:42  trigg

	* weka/core/Attribute.java (1.25): Fixed copy method for date
	attributes.

2001-10-03 17:38  trigg

	* weka/filters/AttributeTypeFilter.java (1.11): Fixed bug in how
	output attributes were created.

	* weka/gui/GenericObjectEditor.java (1.27): Added a check to
	prevent itemStateChanged from creating a new object (with default
	values) when the current object and the selected item are the same
	type. Events fired when creating a new GenericObjectEditor were
	causing the object to be configured to be overwritten.

2001-10-01 15:50  rkirkby

	* weka/classifiers/trees/m5/Matrix.java (1.5): Optimized the matrix
	multiply function. Credit goes to Ken Geis for sharing his code
	with us.

2001-09-28 16:30  rkirkby

	* weka/classifiers/lazy/kstar/KStar.java (1.8): Fixed case where
	predicted distribution of an instance sums to zero. Was throwing an
	exception when normalizing the array.

2001-09-26 10:29  rkirkby

	* weka/classifiers/trees/m5/M5Prime.java (1.17): Disallowed illegal
	combination of smoothing on a non-model tree in the GUI.

2001-09-20 13:45  mhall

	* weka/gui/GenericObjectEditor.props (1.40): Removed an unecessary
	extra space following a property value.

2001-09-17 15:08  rkirkby

	* weka/classifiers/Makefile (1.27): Added BVDecompose which should
	have been there long ago.

2001-09-06 14:13  trigg

	* weka/: core/Attribute.java (1.24), core/Instance.java (1.14),
	core/Instances.java (1.34), experiment/InstanceQuery.java (1.12),
	experiment/InstancesResultListener.java (1.6): Added date
	attributes. These are specified in the arff header as:
	
	@attribute <name> date [<format>]
	
	<name> is the name for the attribute <format> is an optional string
	specifying how date values should be parsed/printed (this is the
	same format used by SimpleDateFormat). The default format string
	accepts the ISO-8601 combined date and time format:
	"yyyy-MM-dd'T'HH:mm:ss".
	
	and specified in the data section as the corresponding string
	representations of the date/time. Here's a simple example:
	
	@RELATION timetest @ATTRIBUTE timestamp DATE
	"yyyy-MM-dd'T'HH:mm:ss" @DATA 2001-04-03T12:12:12
	2001-05-03T12:59:55
	
	Date attributes return true for isNumeric(). (the double value
	stored in each Instance is the double representation of
	Date.getTime()).
	
	The database support (in InstanceQuery) for dates is implemented
	but needs to be tested.
