* discriminantAnalysis package now contains an implementation for LDA and QDA * New largeScaleKernelLearning package - contains filters for large-scale kernel-based learning * New iterativeAbsoluteErrorRegression package - provides a meta learner that fits a regression model to minimize absolute error * New percentageErrorMetrics package - provides plugin evaluation metrics for root mean square percentage error and mean absolute percentage error * New niftiLoader package for loading a directory with MIR data in NIfTI format into Weka * New elasticNet package, courtesy of Nikhil Kinshore * New netlibNativeOSX, netlibNativeWindows and netlibNativeLinux packages providing native reference implementations (and system-optimized implementation in the case of OSX) of BLAS, LAPACK and ARPACK linear algebra * Packages that were using JAMA are now using MTJ DictionarySaver converter can be used to create a dictionary file * FixedDictionaryStringToWordVector filter allows the use of an external dictionary for vectorization. * GUI package manager now has a search facility Engine completely rewritten from scratch with a simplified API * GaussianProcesses now handles instance weights * General efficiency improvements in core, filters and some classifiers Faster operation with the option to use native libraries for even more speed * JAMA-based linear algebra routines replaced with MTJ. Note: It might take a while before has propagated all the files to its mirrors. The Pentaho Weka micro site at will be updated to reflect the new releases soon. Packages for Weka>=3.7.2 can be browsed online at: Pentaho data mining community documentation: To make these go away simply delete the r file in ~/wekafiles/packages and then restart Weka. NOTE 3: When upgrading to Weka 3.8.0/3.9.0, Users of Weka 3.7.x may notice some exceptions thrown in the console relating to the package manager. From the GUIChooser you can alter the LAF by selecting 'Settings' from the 'Program' menu (a restart will be required if the LAF is changed).

Furthermore, it is more performant under Mac OS X than the default Aqua LAF - we found that the Explorer's list of attributes becomes very slow to update on datasets with a large number of attributes when using the Aqua LAF on OS X. We feel that this looks reasonable under the three main OS's. NOTE 2: We have changed the default look and feel in Weka 3.8 and 3.9 to 'Nimbus'. A quick check of the javadoc for 3.8 will hopefully show what is necessary.

Similarly, developers using 3.6 will find that there are some small changes that they need to make to their code in order to compile against 3.8. Models will need to be recreated in Weka 3.8. Unfortunately, there is no workaround for this. NOTE 1: Users of Weka 3.6 will find that serialized models created in 3.6 cannot be used in 3.8. We feel that the package management system is a nice mechanism for allowing stable Weka to be extended with new features, while at the same time maintaining a stable core. The development version receives bug fixes and new features.ДЈ.8.0 and 3.9.0 are the first second digit version increases since stable 3.6 was released in 2008! At this point there is no functional difference between 3.8.0 and 3.9.0 - 3.7 has been branched to create 3.8 and development of core Weka will continue in 3.9. Stable Weka 3.6 and 3.8 receive bug fixes only.
