Rafael M. O. Cruz, Robert Sabourin, George D. C. Cavalcanti

Abstract: Highlights•10 new sets of meta-features to measure the competence of a classifier are proposed.•A meta-feature selection scheme is proposed based on the formal definition Oracle.•A BPSO is used for optimizing the performance of the meta-classifier.•The proposed method achieves results closer to the ideal dynamic selection technique.•The proposed framework outperforms several dynamic selection techniques.
