JDMP

Try this example:

ClassificationDataSet dataSet = DataSetFactory.IRIS();
 
SVMClassifier svm = new SVMClassifier();
 
svm.train(dataSet);
svm.predict(dataSet);
 
dataSet.showGUI();

If you get an error, you probably need LibSVM in your classpath.

JDMP has most analysis methods for classification tasks: We support Naive Bayes, Neural Networks and classification trough regression directly, Support Vector Machine through the LibSVM library and many more classifiers through the Weka machine learning package.
Bayesian Networks, clustering and optimization methods are still experimental.
