Abstract: : It is the most critical for finding the best kernel to apply the kernel-based algorithms in practice, such as support vector machines (SVMs) for classification. The selection is tightly connected to the encoding of our prior knowledge about the data and the pattern type of the task. In this paper, we discuss the kernel trick and its selection and construction methods for SVM classification. In addition we employed distance learning to construct RBF kernels. Experiments on several dataset proved the advantages of distance metric learning for kernel construction.

 

Keywords: Kernel, SVM, Distance learning.
