By using the kernel function, the input space is mapped to a high dimension feature space where the data are expected to be more separable, the initial centroids in the feature space are selected by applying the KRA algorithm, and the large and small clusters are partitioned and the outliers can be split from the large clusters iteratively after the kk-means clustering. As a result, the audit data can be clustered better. Secondly, the closed sequential patterns mining algorithm CloSpan is improved according to the restrictions that is composed of the axis properties and reference properties.
该方法通过核函数把数据样本空间映射到一个高维的特征空间，使数据在新的空间中具有更好的可分离性；在特征空间采用KRA算法选取初始聚类中心，然后在核k-means聚类的基础上，划分出大簇小簇并在大簇中分离出异类再次进行核聚类，从而不断地优化聚类结果。

When Shigella flexneri 2a 2457T is cultured at 30℃, it's phenotypically avirulent; when grown at 37℃, its virulence improves greately. There is clear evidence that the temperature-dependent expression of the virulence genes is controlled by H-NS protein.
痢疾杆菌在30℃时不具有侵袭力，37℃时毒力明显增强，已有的研究表明这种依赖于温度的毒力基因的表达受H-NS蛋白的调控。H-NS是一种重要的类核相关蛋白，在革兰氏阴性菌中普遍存在，能够调控大量基因的表达。

Researches on kernel clustering algorithms. After combining K-means clustering algorithm and the theory of kernel-based learning algorithms, we propose a fast kernel K-means clustering method which is based on CPD kernel. The experiment results indicate that the clustering effect of the algorithm is better than that of K-means algorithm, the clustering speed of the algorithm is also fast than that of K-means algorithm.
