Enhancing the performance of AdaBoost algorithms by introducing a frequency counting factor for weight distribution updating

Abstract

This work presents a modified Boosting algorithm capable of avoiding training sample overfitting during training procedures. The proposed algorithm updates weight distributions according to amount of misclassified samples at each iteration training step. Experimental tests reveal that our approach has several advantages over many classical AdaBoost algorithms in terms of error generalization capacity, overfitting avoidance and superior classification performance. © 2012 Springer-Verlag.
