    Removed some stuff that shouldn't have been there
gui/GenericObjectEditor.html (1.38.2.3)
2005-03-04 03:47 eibe
    The *.props files in the the gui package know support multiple roots (i.e. roots other than weka.*). Thanks, Peter.
gui/GenericObjectEditor.html (1.38.2.2) gui/GenericPropertiesCreator.html (1.1.2.2)
2005-02-28 03:43 eibe
    Made Instance(Instance) constructor protected. copy() method should be used instead. Changed some other classes accordingly. (Note that these classes may not have worked properly with sparse instances before.)

    Fixed bug in Conviction measure computation
associations/AprioriItemSet.html (1.2.2.1)
2005-02-24 20:37 eibe
    Changed so that the training data is randomized the same way for every learning scheme/parameter combination/set of attributes being compared. This is important if the base learner is sensitive to the order of the instances.
attributeSelection/RaceSearch.html (1.14.2.1) classifiers/meta/CVParameterSelection.html (1.27.2.1) classifiers/meta/MultiScheme.html (1.18.2.1)

    Small bug fix from Peter.
core/xml/XMLSerialization.html (1.1.2.5)

    Datasets are now sorted alphabetically in Experimenter SetupPanel. Small bug fix in setting precision for output in Experimenter ResultPanel. Workaround for XMLSerialization for Java 1.5.

    AODE is now and updateable classifier, thanks to Nicolas Saunier.
classifiers/bayes/AODE.html (1.8.2.1)
2005-02-13 23:59 eibe
    Changes for making evaluation return correct results for a classifier even if buildClassifier() does not initialize the classifier correctly. This is for those people who are not aware of the requirement for initialization (given in the Javadoc and the book) and do not run CheckClassifier to test their classifier for correct behaviour. Note that classifiers that are not initialized correctly in buildClassifier() may still not work properly when used with meta classifiers that perform cross-validation.

    Checking in improvements by Steve Hugg: (a) change to the PrincipalComponents to shorten the names of the transformed attributes, sorting them by highest-magnitude coefficient first, and (b) LRU cache for kernels. Also put in Bernhard's full cache for all kernels.
