Volata

Volata is a generic machine learning system implemented in Java that provides ensemble methods like AdaBoost, Bagging, GloBoost and so on. Volata must be instanciated with generalization operators called lgg (least general generalization). Examples of such instanciations are given for classification tasks using attribute-value, sequences and trees representations of examples.
