Abstract The AdaBoost algorithm is an ensemble algorithm that combines multiple base learners through reasonable strategies to
:
generate a strong learner. Its performance depends on the accuracy and diversity of the base learners. However the poor

classification accuracy of weak learners often leads to poor performance of the final strong classifier. Therefore in order to further

improve the classification accuracy of the algorithm this paper proposes an MDTAda model which first uses the Gini index to
ꎬ ꎬ
iteratively construct an incomplete decision tree. Then add a simple classifier to the non ̄pure pseudo ̄leaf nodes of the decision tree to
generate MDT model decision tree use MDT as the base classifier of the AdaBoost algorithm and weighted average to generate
