基于核的学习机研究综述*

近年来核学习机已经成为机器学习界的一个热点问题，并在许多领域中得到了成功应用；然而作为一种尚未成熟的新技术，核学习机仍然存在很多局限性。介绍了核方法的基本思想，从有监督和无监督学习算法两方面对基于核的学习机进行了梳理，着重指出了核学习机研究中存在的问题和值得关注的研究方向，以期对核方法研究领域有较全面的把握。

Kernel-based learning machines research overview

It is believed that the study of kernel methods is becoming a new hot area in the field of machine learning recently. Kernel methods have been applied in many fields successfully. But as a new technique,there are still plenty of limitations in kernel-based learning machines. This paper firstly analyzed the basic ideas of kernel-based learning machines then provided an introduction to some kinds of kernel learning machines developed recently from supervised learning and unsupervised learning. Pointed out the...
