moved the remaining dynamic discovery of classes (via ClassDiscovery.find) into GenericPropertiesCreator.props/GenericObjectEditor.props. This should enable environments without the possibility of dynamic class discovery, e.g., Eclipse, to use these classes as well (as long GenericObjectEditor.props is maintained) |

Changed so that only the weka.jar goes into the OS X application as a resource, all other files go into a separate directory in the disk image |

initModel is now also called in setModelFile(File) and getCapabilities(), otherwise the capabilities cannot be determined correctly: https://list.scms.waikato.ac.nz/mailman/htdig/wekalist/2007-December/011783.html |

When saving trained model to binary file now saves training header (like the Explorer does). Similarly, when loading binary model attempts to load the header from the stream as well. |

support of an attribute range to base the distance calculation on is now mandatory for all distance functions |

new distance functions (Manhattan and Chebyshev) which share the same abstract superclass as the Euclidean distance function: NormalizableDistance |

Now throws an exception if NaN occurs during standardization. This avoids introducing missing values into the filtered data set in this situation. |

removed "final" from getOutputFormat method declaration since that caused VerifyError exceptions in derived filters on Mac Books: https://list.scms.waikato.ac.nz/mailman/htdig/wekalist/2007-October/011339.html |

test for missing values missed the last column (in case it wasn't the class attribute!) |
| 2007-09-10 21:53 fracpete |
mathematical expression got only evaluated for toString/getMeasure, but for actual setup of filter/classifier. Didn't pop up as error since most Weka schemes do NOT check the input in the get-method (you only get wonky results). Was discovered by M. Fatih Akay using LibSVM, since LibSVM threw an exception in case of invalid parameters, but the values would have been valid IF the expression would have been evaluated. |

classifyInstance returned the probability instead of the index from the class probability array for nominal classes (in case of average/product/majority/min/max rule). Thanks to Samuel Robert Reid |
| 2007-09-07 07:02 fracpete |
tokenizer could not be serialized due to unserializable StringTokenizer class. changed m_Tokenizer to transient. |
| 2007-09-03 22:11 fracpete |
removed classifyInstance method, since there were discrepancies between the labels returned by classifyInstance and the best one returned by distributionForInstance (svm_predict returned other labels than svm_predict_probability???) used version of libsvm: 2.84 |

Fixed bug that prevented quoted ? from being parsed as a label rather than a missing value |

stopwords no longer get ignored |

savers were too restrictive in writeBatch method: instead ALWAYS having a file to write to, one needs only either a file OR a stream (both are used through a Writer) |
| 2007-08-01 04:06 fracpete |
added general Jython support Jython classes that are derived from weka.classifiers.Classifier can be executed with the wrapper classifier weka.classifiers.JythonClassifier (serializing/deserializing a trained model is unfortunately NOT possible, a call of buildClassifier is always necessary after deserialization) |

Instance variable holding an Evaluation object was not set to null after buildClassifier, resulting in not serializable exception in Experimenter |

added the "output of additional attributes" option to the "more options" dialog in order to output attribute values alongside the predictions (just like on the commandline with "-p") |

statement variables are now transient (otherwise an exception is raised that these objects aren't serializable) added checks whether a DB connection is active (after de-serializing for instance) |

removed restriction that nominal attributes have to have at least one attribute. ARFF files generated from databases can have empty nominal attributes, e.g., "Summary" from a results table of the Experimenter may not be filled in (only missing values).

source code generation now generates a static Weka filter |
| 2007-06-19 04:28 fracpete |
fixed "sourcing" of classifiers:
- Explorer outputs now the complete class, not just the static class, but also the wrapper class
- wrapper class has now a main method and a toString method to enable calls from the commandline like with any other classifier
- reversed all "public class" to "class" again
- class attribute now gets set to missing explicitly before the static class is called ("classify")
- updated weka.classifiers.CheckSource to reflect changes (source code has to be derived from weka.classifiers.Classifier now)
- fixed OneR's toSource method

on Macs the updateCurrentConverter() method crashes with a NullPointerException if the setAcceptAllFileFilterUsed(boolean) method is used before the dialog is even displayed (e.g., in the showSaveDialog(Component) method).
