Classifiers compatible now with Weka 3.5.8 - 2008-07-16 16:32 NZ - FracPete
The classifiers now work together with the new release of Weka, Weka 3.5.8. Download as usual in the Downloads section.

Classifiers work with Weka 3.5.6 now - 2007-06-05 13:54 NZ - FracPete
The classifiers now work together with the new release of Weka, Weka 3.5.6. Download as usual in the Downloads section.

JUnit tests added - 2006-10-18 13:07 NZ - FracPete
The classifiers now have JUnit tests as well and work together with the current CVS version of Weka. They will also work together with the next release of the developer version Weka, since the API won't get modified till then, only bugfixed. Download as usual in the Downloads section.

Award!! - 2006-09-27 14:31 NZ - Bernhard
A submission based on algorithms developed for this project won both an award for accuracy as well as one for creativity. [www]

Classifiers upgraded to latest CVS - 2006-04-24 16:28 NZ - FracPete
All the classifiers have been upgraded to the latest CVS Weka, i.e., they all have Capabilities now. You can download them in the Downloads section.

Beta release of Weighting - 2005-10-26 17:01 NZ - FracPete
A beta release of a new meta classifier is available: Weighting. More information can be found in the classifier description.

Beta release of Chopper - 2005-10-11 09:16 NZ - FracPete
A beta release of a new meta classifier is available: Chopper. More information can be found in the classifier description.

YATSI results on UCI datasets with 20 iterations - 2005-09-27 15:33 NZ - FracPete
Results for YATSI experiments (weka39a-d) with the original UCI datasets instead of the binarized versions and 20 instead of 10 iterations are now online.
The 1/99% split experiment is now available with 10 (weka39a), 20 (weka39a2) and 50 (weka39a3) neighbors.

Beta release of YATSI - 2005-08-25 13:18 NZ - FracPete
A beta release of a new meta classifier is available: YATSI - Yet Another Two Stage Idea. More information can be found in the classifier description.

VotedFolds is now Dagging in Weka - 2005-08-24 10:47 NZ - FracPete
The VotedFolds classifier has become an official Weka classifier and is available from the CVS. It changed its name to Dagging, i.e., the XML files of the experiments till today need to be modified.

Another change, that affects the display of generated graphs, is the following: in each graphs folder (also in each sub-folder) there's now a file called All_graphs.html that contains a preview over all graphs.

Another batch for TwoStageCollective - 2005-08-23 13:13 NZ - FracPete
Another batch of results (weka31a-c) for the TwoStageCollective in combination with the VotedFolds algorithm are online. This experiment uses only small datasets (missing results are due to too little instances, i.e., more folds than instances). The VotedFolds meta classifier was used to speed up SMO in particular.

New results for TwoStageCollective - 2005-08-22 11:09 NZ - FracPete
New results (weka30a-c) for the TwoStageCollective in combination with the VotedFolds algorithm (check out the sources from today) are online. This experiment uses only big datasets (missing results are due to OutOfMemory exceptions, even though using 1.2GB for the JVM). The VotedFolds meta classifier was used to speed up SMO in particular.

Results for LLGC - 2005-08-19 11:30 NZ - FracPete
Results (weka29a-c) for the LLGC algorithm (testing various parameter constellations) have been uploaded in the Experiments section.

Setup for TwoStageCollective - 2005-07-28 14:03 NZ - FracPete
Special setup for the TwoStageCollective classifier: in both stages the same classifier is used and only 1 iteration (i.e., no flipping happens). The results (weka27a2/weka27b/weka27c) can be found here.
