Matlab Classification Toolbox contains implementations of the following classifiers: Naive Bayes, Gaussian, Gaussian Mixture Model, DecisionTree and Neural Networks. This toolbox allows users to compare classifiers across various data sets.
A tool based on the model proposed by Bellman & Zadeh (1970) fuzzy logic (fuzzy sets) decision support paper. The first version of the application was developed in Java (pure java + jgoodies and some other APIs).
Now it is being rewritten using nebular, a pure Java fuzzy API.
