A Classifier Ensemble of Binary Classifier Ensembles

Hamid Parvin, Hamid Alinejad-Rokny, Sajad Parvin
2013 International Journal of Learning Management Systems  
The aim of a pairwise classifier is to separate one class from another one.  ...  Indeed although usage of pairwise classification concept instead of multiclass classification concept is not new, we propose a new pairwise classifier ensemble with a very lower order.  ...  So first an arbitrary number of binary classifier ensembles are added to main classifier. Then results of all these binary classifier ensembles are given to a set of a heuristic based ensemble.  ...
