In addition, this algorithm is not only insensitive to initial clustering number just like traditional methods, but also free of the optimization process for kernel parameters due to the use of conditionally positive definite kernel.

此外，该算法不再像传统基于聚类的辨识算法那样对初始的聚类个数敏感，而且由于条件正定核的使用，使得辨识算法免去了核参数优化的过程。

A conditionally positive definite kernel based fuzzy C-means clustering algorithm is used to make a partition for the data set.

传统模糊C均值聚类方法依赖于数据分布形状，并且对孤立点敏感，这势必影响到最终的模型性能。

This paper presents a stability criterion for design iterative learning controller. From the criterion,one can change the design problem into finding a positive definite discrete matrix kernel. It has been shown that what kind of variable can be controlled by the iterative learning,(2) and what kind of filter can be included into the controller.

摘要提出了一种针对自学习控制的稳定性判据，应用这一稳定性判据将自学习控制器的设计转化为寻找正定离散矩阵核，从而回答了两个问题，其一什么样的量可以通过自学习叠代加以控制，其二学习叠代中什么样的滤波环节的引入不会影响学习收敛性。

The method improves performance of KPCA by reasonably combining a local conditionally positive definite kernel and a global kernel. The experiment results indicate the new kernel function certainly improves the performance of KPCA.

利用组合核函数提高核主分量分析的性能，该方法将一个全局核函数与一个新的局部核函数条件正定核函数进行合理组合，从而提高KPCA所提取特征的质量。
