经过我的实验,发现在基于模板法的object detection或者classification中,将Pyramid Histogram of Oriented Gradients (PHOG)和Spatial Pyramid Matching还有其他特征,如果你喜欢用的话,进行多核学习,效果其实很好。我在Bangpeng Yao的乐器数据集上做的实验,和他的论文“Grouplet: A Structured Image Representation for Recognizing Human and Object Interactions”进行了对比,结果要好,虽然好的不是很多,但是总能好个5%左右,关键的一个问题是,Yao的基于Apriori特征挖掘算法复杂度实在是太高太高太高了...

Kernel Functions
Below is a list of some kernel functions available from the existing literature. As was the case with previous articles, every LaTeX notation for the formulas below are readily available from their alternate text html tag. I can not guarantee all of them are perfectly correct, thus use them at your own risk. Most of them have links to articles where they have been originally used or proposed.

The Linear kernel is the simplest kernel fun...
