改进的基本顺序聚类算法，算法包括两个阶段，第一个阶段是将x的一些向量分配到聚类中来形成类；在第二个阶段中，没有被分配的向量第二次参与算法，并分配到合适的类中。-Improved basic sequential clustering algorithm，The algorithm consists of two phases, the first stage is some vector x is assigned to the cluster to form a class　In the second stage, has not been assigned a vector second time algorithm, and assigned to the appropriate class.
