一种基于样本加权的合成多核学习方法
A new summation multi-kernel learning method based on sample weighting
摘要
Abstract
Multi-kernel learning is a new research hotspot in current kernel machine learning field.By mapping data into the high dimensional space,kernel methods increase the computing performance of linear classifiers such as support vector machines,and it is a convenient and effective way to deal with nonlinear pattern recognition and classification.However,in some complex situations,such as heterogeneous data or irregular data,large sample size and non-fiat sample distribution,the kernel learning method based on single kernel function cannot completely meet the requirement,so it is necessary to develop multiple kernel functions in order to get better results.We propose a new summation multi-kernel learning method based on sample weighting which can be weighted by the capability of how much a single kernel function can fit the sample.Experiment analysis on several data sets shows that the proposed method can obtain high classification accuracy.关键词
