As an alternative to MultiFilter, you can nest meta learning schemes such as FilteredClassifier. And you can also use FilteredClassifier as a base classifier in AdaBoost, etc., if you want to apply a filter to build an ensemble classifier.
What I am looking for is ensemble of selection filters not classifiers. How
can I group a set of selection filter algorithms such as GainRation, Genetic
Search, and CFS for example all togother before using or passing the reduced
set to be evaluated by a classifier. How such thing can be implemented in
