Changed year and URL in LogPanel.
  • gui/explorer/Explorer.java (1.33)
2005-07-04 00:56 eibe
FilteredClassifier now extends SingleClassifierEnhancer. Note that this means that the double hyphen construct now needs to be used to specify the classifier options. Another change: Discretize is now the default filter.
  • classifiers/meta/FilteredClassifier.java (1.21)
2005-07-04 00:54 eibe
Fixed some bugs in handling of option setting errors.
  • classifiers/SingleClassifierEnhancer.java (1.3)

Decorate now extends RandomizableIteratedSingleClassifierEnhancer for simplified option handling. Unfortunately, the letters for the command line options had to be changed. What used to be I is now E, and what used to be M is now I. Also, the maximum and desired number of iterations are now both set to 10 by default (instead of 50 and 15 respectively).
  • classifiers/meta/Decorate.java (1.4)
2005-07-03 23:16 eibe
Now allows random codes with fewer columns than classes (handy for datasets with lots of classes). Now implements RandomizableSingleClassifierEnhancer for easier option handling.

2005-07-03 22:55 eibe
Changed letter for command line option speciyfing tolerance parameter as it conflicted with the option for specifying a test set.
