- explorer/PreprocessPanel.java (1.13): - Changed to use
- Instances.FILE_EXTENSION
- 1999-12-08 14:17 trigg

- Instances.FILE_EXTENSION
- 1999-12-08 14:17 trigg

- CostSensitiveClassifierSplitEvaluator.
- 1999-12-08 14:15 trigg

- suggested filename extension for arff files.

- * weka/classifiers/CostSensitiveClassifier.java (1.3): - Uses
- suggested cost file extension CostMatrix.FILE_EXTENSION.
- 1999-12-08 14:10 trigg
- * weka/classifiers/CostMatrix.java (1.4): - Changed to permit
- non-zero diagonal cost entries. Added a normalize method to convert
- to a matrix with zero valued diagonal entries.
- 1999-12-08 14:08 trigg
- * weka/classifiers/Evaluation.java (1.22): - Changed handling for
- cost-sensitive evaluation. Confusion matrix no longer includes cost
- factors (too confusing), similar with true/false positive rates.
- Replaced non-intuitive correct/incorrect with cost with average
- cost and total cost. Command line option -m now only specifies
- cost-sensitive evaluation, for cost-sensitive prediction use one of
- the cost-sensitive meta schemes.
- 1999-12-06 15:52 eibe
- * weka/classifiers/DecisionStump.java (1.9): Fixed bug that
- produced incorrect decision stumps for nominal attributes when the

- explorer/ClassifierPanel.java (1.20), explorer/ClustererPanel.java
- (1.10), explorer/PreprocessPanel.java (1.12): - Changed
- FileChoosers to default to the current directory rather than user's
- home (on Mac and NT, where the user's home is often nowhere near
- anything useful, the current directory makes much more sense. The
- user's home is still only one click away).
- 1999-12-06 10:10 trigg
- * weka/: experiment/CostSensitiveClassifierSplitEvaluator.java
- (1.1), gui/GenericObjectEditor.props (1.8): - Added a classifier

- return the average cost.

- 1999-12-02 19:33 trigg
- * weka/classifiers/Bagging.java (1.9): - Added an option for
- resamples to be a different size to the input training set (for
- superlinear schemes, reducing this can give large speedups).
- 1999-12-02 19:32 trigg
- * weka/classifiers/CostMatrix.java (1.3): - Added a method to
- generate a default cost matrix for a set of instances that weights
- errors proportional to the ratio of the predicted to actual class
- (i.e. higher cost for predicting a rare class as a common class)
- 1999-12-02 19:30 trigg
- * weka/classifiers/Evaluation.java (1.20): - Removed debugging
- output of cost matrix
- 1999-12-02 19:29 trigg
- * weka/classifiers/DistributionClassifier.java (1.3): - Fixed typo
- 1999-12-02 19:29 trigg
- * weka/classifiers/CheckClassifier.java (1.9): - Fixed bug in
- testing whether test class vals are ignored (I think this was only
- due to an earlier change in Instances)

- 1999-11-29 10:27 mhall
- * weka/gui/explorer/AttributeSelectionPanel.java (1.8): Changed so
- that results list shows seach + evaluator, rather than evaluator +
- search.

- * weka/experiment/DatabaseUtils.java (1.6): Increased max string
- size to 300 chars.

- DatabaseResultProducer.java (1.4), InstanceQuery.java (1.4),
- RandomSplitResultProducer.java (1.3), ResultProducer.java (1.2):

- the problem of results being regenerated for stuff that is already
- in a database.
- 1999-11-26 16:33 mhall
- * weka/experiment/PairedTTester.java (1.5): Added the ability for
- standard deviations to be output.

- 1999-11-18 13:47 mhall
- * weka/gui/PropertySheetPanel.java (1.2): Can now display global
- information about the target object as well as individual tip text
- for each property. Editable objects need to have a public String
- globalInfo() method and a TipText() method for each editable
- property. Eg, if some class has get/setBlah() then it needs a
- public String blahTipText() method. Still works fine for classes
- that don't have these methods.
