In order to improve the performance of multi-class semi-supervised classification
a new multi-class Co-Forest algorithm named DSM-Co-Forest is proposed on the basis of D-S evidence theory. First
through MVM mode
the multi-labeled data set is randomly split into multiple binary-class data set to train the base classifiers; then
these base classifiers are used to pick out the high reliability samples from the unlabeled data set by using the evidence combination algorithm; finally
adds these selected samples to the original training set to iteratively update the base classifiers so as to improve the overall performance of the multi-class classifier. Through comparing with other semi-supervised classification algorithms on several public data sets
the feasibility and validity of the proposed algorithm are verified.
