# Weka-3-5-6 Changelog

Designed for use with Apache Ant.

2007-06-01 04:32 fracpete

    updated version

- core/version.txt (1.5)

2007-06-01 04:02 fracpete

    updated to reflect changes in GenericPropertiesCreator.props file

- gui/GenericObjectEditor.props (1.117)

2007-05-31 23:13 fracpete

    added note to Javadoc of add(Instance) method, that string and relational values are not transferred

- core/Instances.html (1.72)

2007-05-31 04:24 fracpete

    Exceptions were thrown in case of nominal attributes with no labels (e.g., returned by the weka.core.converters.DatabaseLoader), added checks regarding the length of the AttributeStats.nominalCounts array

- gui/AttributeVisualizationPanel.html (1.27)

2007-05-31 03:43 fracpete

    up till now, the loaders were broken regarding String and Relational attributes in the incremental case (the Instances structure they were added to didn't get updated regarding string or relational values). hence an interface change was necessary, i.e., getNextInstances got a parameter, an Instances object that gets updated. All dependend classes had to be updated as well.

- gui/explorer/ClassifierPanel.html (1.106)

2007-05-31 03:42 fracpete

    added EMPTY_NOMINAL_ATTRIBUTES and EMPTY_NOMINAL_CLASS to the list of capabilities, since the weka.core.converters.DatabaseLoader can generate nominal attributes without any labels (the corresponding capability for the class only for completeness' sake)

- core/Capabilities.html (1.20)

2007-05-31 02:56 fracpete

    fixed Javadoc comment

    initial import

2007-05-28 21:52 fracpete

    Date values are no longer output as Doubles but as Date strings again
    interestingly enough, the number of seconds seems to differ on Windows (= 986212800000; java 1.5.0_10) and Linux (= 986256000000; java 1.5.0_11) for the same  date (= 2001-04-03)

- core/SparseInstance.html (1.20)

2007-05-26 10:42 fracpete

    removed the SplashScreen for the KnowledgeFlow. somehow didn't start up when run as SDI (MDI worked fine, as well as debugging it - timing issue due to multiple threads?)

- gui/Main.html (1.12)

2007-05-25 00:23 fracpete

    main GUI can be either MDI or SDI driven
    window list menu is now sorted
    added extension mechanism via MainMenuExtension interface

    Moved I/O for reading an ARFF file from weka.core.Instances to weka.core.converters.ArffLoader.ArffReader. This fixes the problem with the ArffLoader reporting wrong line numbers, due to the use of the Instances.readInstance(Reader) method.

- core/Attribute.html (1.44)

2007-05-14 03:39 fracpete

    fixed Javadoc

- gui/GenericPropertiesCreator.html (1.11)

2007-05-14 03:12 fracpete

    added a method to "sanitize" all the filenames, which are based on the relationname: all the slashes, backslashes and colons are replaced by underscores. Was problematic for filters that had filenames in their options, which in turn had a relation name (under windows) containing backslashes as result. This generated an exception in the ArffSaver used directly after the filter.

- gui/beans/Saver.html (1.5)

2007-05-11 03:59 eibe

    Fixed bug in output of coefficients and intercept: they needed to be multiplied by (J-1)/J, where J is the number of classes. This affected LMT and SimpleLogistic.

    filters now return their Capabilities based on the data: in case there's no class attribute set, they'll remove all the types of classes that are supported apart from NO_CLASS, and in case that there's a class attribute present, then the NO_CLASS capability will be removed
    Wavelet filter supports now also nominal attributes (restriction to numeric class was unnecessary)
    AddCluster/ClusterMembership always have to ignore the class attribute for the capabilities because of the clusterers they're using internally
