但其缺点是不能处理混合属性数据，聚类结果对初值有明显的依赖性。

The problem is that both of the two algorithms cannot deal with mixed valued data, and clustering results significantly depend on the initial value.

目前对于数值属性数据的聚类分析已经相当成熟，而对类属性和混合属性数据的聚类分析则并不十分完善。

At present, the clustering analysis about numeric valued data is quite mature, but the clustering analysis about categorical valued and mixed valued data is not perfect.

基于一种用于混合属性数据的距离定义和改进的最近邻分类方法，提出了一种基于聚类的有指导的入侵检测方法。

A clustering-based and supervised intrusion detection method was proposed with new distance definition for mixed-attribute data and improved nearest neighbor classification method.
