I'm trying to combine multiple classifiers (ANN, SVM, kNN, ... etc.) using ensemble learning (viting, stacking ...etc.) .
In order to make a classifier, I'm using more than 20 types of explanatory variables. However, each classifier has the best subset of explanatory variables. Thus, seeking the best combination of explanatory variables for each classifier in wrapper method, I would like to combine multiple classifiers (ANN, SVM, kNN, ... etc.) using ensemble learning (viting, stacking ...etc.) .
By using the meta-learning with weka, I should be able to use the ensemble itself. But I can not obtain the best combination of explanatory variables since wrapper method summarizes the prediction of each classifier.
I am not stick to weka if it can be solved easier in maybe matlab or R.
