updated to reflect changes in GenericPropertiesCreator.props file
|
2007-05-31 23:13 fracpete |
added note to Javadoc of add(Instance) method, that string and relational values are not transferred
|
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
|
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.

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)

2007-05-30 04:02 fracpete |
relational attributes are now filled according to extra parameters (better control over generated data)

added "headless" property, in case the JUnit tests (via "run_tests") need to be run in a headless environment, e.g., via a cronjob

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)

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?)
|
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.

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.

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.
