- 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

- 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.

- 2001-01-15 15:52 trigg
- * weka/: TODO.dtd (1.1), TODO.xml (1.1): First version of files to

- 2001-01-15 11:33 trigg

-
- Added documentation available via the gui.
- 2000-12-20 11:45 trigg
- * weka/classifiers/MultiClassClassifier.java (1.18): Reinserted
- indicator filtering of test instances. Even though classifiers
- shouldn't really be looking at the class attribute of test
- instances, some (such as j48) currently do look at the test
- instance class attribute to find the number of class values.
-
- Maybe we should probably have a policy that classifiers do not
- access the class attribute of test instances (and write test code
- to check this).
- 2000-12-20 11:26 trigg

- out into Range.java
- 2000-12-20 09:49 trigg
- * weka/gui/GenericObjectEditor.props (1.29): Added a couple of

- number of x-val folds if there are not enough training instances.
- 2000-12-13 18:15 trigg
- * weka/filters/Filter.java (1.15): Fixed that case I mentioned
- before. Input buffering is now string-safe.
- 2000-12-13 18:09 trigg
- * weka/classifiers/SMO.java (1.21): Changed internal
- m_dontNormalize variable to m_Normalize. Less stressful on the
- brain when looking at
-
- if (m_Normalize)
-
- than
-
- if (!m_dontNormalize)
-
- No change to command-line or gui use.

- * weka/filters/Filter.java (1.14): Smarter about whether and how
- often String references are flushed. Much speedup for incremental
- filtering.
- 2000-12-12 16:04 trigg
- * weka/clusterers/DistributionMetaClusterer.java (1.3): Took bodgy
- pseudo-WeightedInstancesHandling out of this meta clusterer. See
- log comments for DistributionMetaClassifier for why.
- 2000-12-12 16:03 trigg
- * weka/classifiers/: DistributionMetaClassifier.java (1.4),
- FilteredClassifier.java (1.11), MultiClassClassifier.java (1.16),
- RegressionByDiscretization.java (1.11): Took bodgy
- pseudo-WeightedInstancesHandler out of these meta classifiers. The
- right way to do this is to write a WeightedInstancesMetaClassifier
- and give the user the choice between resampling with/without
- replacement and with varying sizes of post-resampling data.
- 2000-12-11 10:36 trigg
- * weka/filters/Filter.java (1.13): Performs a memory optimization
- after the last instance is retrieved from the output queue between
- batches.
-
- The recent changes to Filter will require updates to any filters
- you have implemented yourself. The changes are:
-
- In your implementation of inputFormat(Instances) you should call
- super.inputFormat(Instances) as the first line.
-
- If your filter requires buffering instances in the first batch, use
- bufferInput(Instance) to do this. Your implementation of
- batchFinished should also call flushInput() (after processing
- buffered instances if necessary).
-
- Other references to m_InputFormat should be replaced by
- getInputFormat().
- 2000-12-11 10:23 trigg
- * weka/classifiers/evaluation/ThresholdCurve.java (1.11): Now
- handles non-integer prediction weights properly.
- 2000-12-11 10:23 trigg
- * weka/filters/AddFilter.java (1.11): Fixed bug introduced by
- Instance.copy() maintaining the dataset reference.
- 2000-12-10 16:18 trigg
- * weka/core/Instances.java (1.26): Made stringFreeStructure more
- efficient.

- (1.2): Updated users of Filters so that incremental use is followed
- by a call to batchFinished() -- this gives memory optimization in
- the case of datasets with string attributes as references to old
- strings are flushed.
- 2000-12-10 13:58 trigg
- * weka/filters/: AddFilter.java (1.10), AllFilter.java (1.5),
- AttributeExpressionFilter.java (1.5), AttributeFilter.java (1.10),

- StringToWordVectorFilter.java (1.4), SwapAttributeValuesFilter.java
- (1.7), TimeSeriesDeltaFilter.java (1.4),

- now work safely with string attributes. Previously, Bad Things
- would happen and the string values would get lost or point to the
- wrong strings when passing through filters.
-
- There is one case (not applicable all known filters) yet to handle,
- see comments in Filter.inputFormat.
- 2000-12-10 13:53 trigg
- * weka/core/Instances.java (1.25): Added a method for quickly
- removing all instances from the dataset.
- 2000-12-10 13:52 trigg
- * weka/core/Instance.java (1.9): copy() now points the copied
- instance at the same dataset as the original instance. This makes
- more sense. If you want the old behaviour, use the equivalent
- constructor.
- 2000-12-10 13:51 trigg
- * weka/core/Attribute.java (1.14): Adding string values no longer
- checks for duplicates (since it's assumed string values are
- typically unique, otherwise they'd be nominal).
-
- Added a method for efficiently copying string values from one
- attribute to another.
- 2000-12-09 14:13 trigg
- * weka/: classifiers/FilteredClassifier.java (1.8),
- core/Instances.java (1.24), filters/StringToWordVectorFilter.java
- (1.3): Moved common code into Instances.
- 2000-12-09 14:13 trigg
- * weka/classifiers/MultiClassClassifier.java (1.13): Less
- restrictive of the datasets it accepts.
- 2000-12-09 11:42 trigg
- * weka/: associations/Associator.java (1.3),
- attributeSelection/ASEvaluation.java (1.7),
- classifiers/Classifier.java (1.7), clusterers/Clusterer.java (1.7):
- Changed makeCopies methods to use Serialization when copying. Now
- copies will also contain any model built by the input object.
- However, this method now works when making copies of objects that
- were not previously able to be created by the command line.
- 2000-12-08 16:13 trigg
- * weka/classifiers/evaluation/ThresholdCurve.java (1.10): Added
- routine for calculating area under ROC curve.
- 2000-12-08 15:30 trigg
- * weka/filters/MakeIndicatorFilter.java (1.7): Changed how output
- indicator values are named.
- 2000-12-08 15:25 trigg
- * weka/classifiers/ThresholdSelector.java (1.12): Little more
- accepting in the auto-name case. Now just wants class values
- starting with "yes" or "pos" (case-insensitive) or equalling "1".
- 2000-12-08 15:17 trigg
- * weka/attributeSelection/StartSetHandler.java (1.4): Fixed buggy
- Revision tag.
- 2000-12-08 15:04 trigg
- * weka/classifiers/ThresholdSelector.java (1.11): Another method
- for picking which class to optimize: value with a positive sounding
- name (yes, pos, positive, 1);
- 2000-12-08 14:12 trigg
- * weka/filters/SpreadSubsampleFilter.java (1.4): Added an option to
- adjust weights of output instances so that the total weight per
- class can be maintained.
- 2000-12-08 11:42 trigg
- * weka/classifiers/evaluation/Prediction.java (1.3): Incorrect
- access on the predicted method.
- 2000-12-08 11:37 trigg
- * weka/classifiers/evaluation/TwoClassStats.java (1.4): Added a
- method to get an equivalent confusion matrix. Perhaps TwoClassStats
- should be changed to use a ConfusionMatrix internally. Advantage:
- loading/saving/applying costs. Disadvantage: slightly slower,
- slightly more memory.
- 2000-12-08 11:35 trigg
- * weka/classifiers/Evaluation.java (1.38): Added a couple of
- comments.
- 2000-12-08 11:34 trigg
- * weka/classifiers/CostSensitiveClassifier.java (1.6):
- setCostMatrix and setOnDemandDirectory now set the cost matrix
- source appropriately.
- 2000-12-08 11:33 trigg
- * weka/classifiers/CostMatrix.java (1.7): A couple of extra
- comments. No actual code change.
- 2000-12-06 09:46 trigg
- * weka/classifiers/MetaCost.java (1.5): setCostMatrix and
- setOnDemandDirectory now make the appropriate setting to
- setCostMatrixSource. We should probably go through properties in
- other schemes and get the property dependencies updating
- appropriately.
- 2000-12-05 13:58 trigg
- * weka/classifiers/Evaluation.java (1.37): Partial refactoring of
- the main evaluation routine.
- 2000-12-04 15:22 trigg
- * weka/classifiers/AttributeSelectedClassifier.java (1.5): Fixed
- small bug in Revision tag.
- 2000-12-04 15:18 trigg
- * weka/attributeSelection/SymmetricalUncertAttributeEval.java

- 2000-12-04 15:14 trigg
- * weka/attributeSelection/: ErrorBasedMeritEvaluator.java (1.3),
- RankedOutputSearch.java (1.6): Fixed small bug in Revision tag.
- 2000-12-04 12:26 trigg
- * weka/classifiers/ThresholdSelector.java (1.10): Added different
- options for choosing which class value to optimize for.
- 2000-12-04 10:52 trigg
- * weka/classifiers/ThresholdSelector.java (1.9): Converted into a
- DistributionClassifier, where the probability distribution is
- rescaled so that the selected threshold corresponds to 0.5 in the
- output distribution. Essentially means this metaclassifier just
- does two linear transformations on the output of the subclassifier.
- 2000-12-03 16:32 trigg
- * weka/classifiers/evaluation/ThresholdCurve.java (1.9): Now
- possible to get the names of the attributes used for the various
- measures as static fields.

- 2000-11-29 16:13 trigg
- * weka/classifiers/FilteredClassifier.java (1.7): The memory
- optimization to remove references to old strings after filtering
- wasn't passing the class attribute through. Fixed.
- 2000-11-24 13:11 mhall
- * weka/gui/explorer/Explorer.java (1.18): Oops. Changed addPlot to
- setMasterPlot when setting up Visualize panel.
- 2000-11-24 12:55 mhall
- * weka/gui/explorer/Explorer.java (1.17): Visualize panel is now
- initialized using a PlotData2D object rather than calling
- setInstances.
- 2000-11-24 12:54 mhall
- * weka/gui/visualize/VisualizePanel.java (1.17): The setInstances
- method does not add an instance number attribute (for the sake of
- the UserClassifier).
- 2000-11-24 11:40 mhall
- * weka/gui/explorer/: ClassifierPanel.java (1.41),
- AttributeSelectionPanel.java (1.22), ClustererPanel.java (1.28):
- Visualizable results now have instance number attribute.
- 2000-11-24 11:39 mhall
- * weka/gui/visualize/: PlotData2D.java (1.9), VisualizePanel.java
- (1.16): Made adding an instance number attribute to visualizeable
- instances optional.
- 2000-11-23 14:16 mhall
- * weka/gui/visualize/PlotData2D.java (1.8): Now preserves original
- relation name (used to get overwritten by the filter that is used
- to add the instance number attribute).
- 2000-11-22 17:27 trigg
- * weka/classifiers/MultiClassClassifier.java (1.12): Optimization
- when using on two-class problems -- doesn't build a redundant
- model.
- 2000-11-22 08:54 mhall
- * weka/gui/GenericObjectEditor.props (1.27): Added SimpleKMeans

- * weka/filters/SplitDatasetFilter.java (1.6): Option to generate
- data that is not stratified even if class index is set.
- 2000-11-01 16:25 mhall
- * weka/classifiers/AdditiveRegression.java (1.4): Added option for
- setting the maximum number of iterations to perform.

- * weka/gui/experiment/RunPanel.java (1.14): No longer "says waiting
- for remote tasks to finish" if experiment is not a
- RemoteExperiment.
