基于 Boosting框架的非稀疏多核学习方法
Non-sparse multiple kernel learning method based on Boosting framework
摘要
Abstract
Focus on the problem that the traditional classifier ensemble learning methods always integrated a single optimal classifier into the strong one,and the others,which maybe be useful to the optimal,were discarded simply in every Boosting iteration.This paper proposed a non-sparse multiple kernel learning method based on Boosting framework.At every iteration, firstly,this method selected a subset from the training dataset,then trained an optimal individual classifier by regularized non-sparse multiple kernel learning method with this subset,which was obtained by optimizing the non-sparse combination of M basic kernels.It retained some good kernels and discarded the bad ones through imposing LP-norm constrain on combination coefficients,and leaded to a selective kernel fusion and reserved more useful feature information.Lastly,these individual clas-sifiers were combined into the strong one.The proposed method has the advantages of ensemble learning methods as well as that of regularized non-sparse multiple kernel learning methods.Experiments show that it gains higher classification accuracy with smaller number of iterations compared with other Boosting methods.关键词
