| 摘 要： | 在核方法的基础上,介绍了一种自潜变量生成模型构造核函数的新方法;并专门探讨了结合生物序列的自身特点,按照该方法提取了几个边际核函数;随后将它们应用于具体的gyrB(旋转酶B亚单位)氨基酸序列分类实验中,实验结果表明边际核具有良好的识别效果及极佳的推广能力,也肯定了此种核构造方法的先进性.

| Abstract: | A new way of kernel design based on latent variable generation model is introduced.The characteristics of biological sequences are discussed,and some marginalized kernel functions are extracted.Then the kernels are applied to the classification of bacterial gyrase subunit B amino acid sequences.Experimental results demonstrate that marginalized kernels embrace good recognition effect and strong generalization capability.The method is affirmed to be an advanced way of kernel design. |
