Note: The table package contains some auxiliary programs for preprocessing the data files.


Bayes is a set of programs to induce a full or a naive Bayes classifier and to classify new data with an induced full or naive Bayes classifier. Since version 4.0 it also allows for a forward selection of attributes based on a separate validation data set.

More details about these programs (included in the source package).

If you have trouble executing the programs on Microsoft Windows, check whether you have the Microsoft Visual C++ Redistributable for Visual Studio 2022 (see under "Other Tools and Frameworks") installed, as the programs were compiled with Microsoft Visual Studio 2022.

A program (bcview) to visualize the classifiers induced with these programs can be found here.

A graphical user interface to these command line programs (BayesGUI, written in Java) can be found here. This graphical user interface does not yet support attribute selection with a validation data set.

Another graphical user interface to these programs, which is based on Gnome 2 and was developed by togaware can be found here. (However, I cannot guarantee that this GUI works with the latest version of the command line programs made available here.)
