摘要
核函数的度量(简称核度量)研究两个核函数(或一个核函数与另一个目标函数)之间相似性的度量方法,是核函数研究中的一个重要课题。系统综述了核度量的研究状况以及目前的研究进展,分析了典型核度量方法的特点及不足,并凝炼了其进一步研究的方向。
Kernel function is a key factor to achieve good performance of kernel methods. Kernel function evaluation, which was one of the important research subjects in kernel functions, aimed at measuring the similarity between two kernel functions or between a kernel and a target function. This paper systematically surveyed the research state and advances in kernel function evaluation. Analyzed the typical kernel evaluation methods with the corresponding characteristics and disadvantages. In addition, summarized further research directions which were worth attention.
