Abstract

In view of the low accuracy and classification efficiency of binary tree support vector machine multi-classification algorithm, this paper proposed a binary tree fuzzy multi-classification algorithm based on auxiliary punishment factor(PF-BTSVM). The algorithm constructed an approximate complete binary tree based on the maximum and minimum sample distance and centroid distance, which improved the classification efficiency of the whole structure. It used the fuzzy membership function and the positive and negative auxiliary penalty factors to screen the training set, eliminated the useless and noise samples for the classification, which improved the training set and weakened the hyperplane offset in the unbalanced classification. Experimental results on data sets show that compared with other binary tree multi-classification algorithm, the proposed algorithm not only improves the classification accuracy and stability, but also speeds up the training and classification, and this advantage is more obvious when the degree of imbalance in classification is larger.
