Now uses less memory. A copy of the edited object is now returned (rather than the object itself) when getValue() is called. Previously, for example, fully built classifiers were copied to a backup variable when the OK button was pressed. This can quickly gobble up lots of memory when large data sets are being used.

2006-06-09 04:43 eibe

added post-processing support for generated data (class PostProcessor and process-method)
if a classifier performs worse than ZeroR it's no longer considered "failed"
  • classifiers/CheckClassifier.java (1.16.2.2)
2006-06-07 22:48 fracpete
cleaned up imports
