how to determine the weights of individual classifier in order to get more accurate results becomes a question that need to be solved.An optimal weight learning method is presented in this paper.First
the training samples are respectively input into the multi-classifier system based on Dempster-Shafer theory in order to obtain the output vector.Then the error is calculated by means of figuring up the distance between the output vector and class vector of corresponding training sample
and the objective function is defined as mean-square error of all the training samples.The optimal weight vector is obtained by means of minimizing the objective function.Finally
new samples are classified according to the optimal weight vector.The effectiveness of this method is illustrated by the UCI standard data set and electric actuator fault diagnostic experiment.
