摘要:
We investigate the characteristics of hard margin support vector machine using a real-world handwriting data. The number of support vectors and distance of margin are two investigated objectives in this work. The structural risk of support vector machine is influenced by the distance of margin that is decided by settings of the kernel function and it parameter. We found that number of support vectors are as the same when the parameter of kernel functions are changed, but the distance of margin is highly influenced by the parameter of kernel functions, which is related to the structural risk of established support vector machine. The handwriting data are not always mixed together in their original representation space. Some of them are linear separable, but some of them are not. We should design a group of classifiers to handle this real-world handwriting application by considering these characteristics and the primary discoveries of this work. © 2019, Springer Nature Singapore Pte Ltd.
