This paper proposes an algorithm of division and multi-level clustering with multi-strategy optimization,which bases on study of today's mature algorithms.

本文在研究已有成熟算法的基础上,提出了基于分治多层聚类的话题发现算法,其核心思想是把全部数据分割成具有一定相关性的分组,对各个分组分别进行聚类,得到各个分组内部的话题,然后对所有的微类再进行聚类,得到最终的话题,在聚类的过程中采用多种策略进行优化,以保证聚类的效果。

FCM algorithm is a clustering algorithm based on the division of its thinking is that it is making is divided into clusters with the greatest similarity between the object and different minimum similarity between the clusters.

FCM算法是一种基于划分的聚类算法,它的思想就是使得被划分到同一簇的对象之间相似度最大而,不同簇之间的相似度最小。

PCOS seemed to display a familial clustering phenomenon, 40.0% patients having family history. The research showed that the degree of oligomenorrhoea was more serious in the patients who had a family history and the rate of amenorrhoea was high (18.9%).

PCOS具有家族聚集性,有家族史的患者月经稀发程度较无家族史者严重,闭经发生率更高(18.9%);激素水平上,T、黄体生成素值较无家族史者增高,差异有统计学意义,而月经初潮年龄、体重指数、E2和LH/FSH比值的增高无差别。

An adaptive grid scheme controlling cell area is used to generated grids in the divergent section of symmetric annular nozzle, and the generated grids are used in the flowfield calculation through the uncoupled way. The elliptic equations are used to generate grids in three dimensional regions of FDN divergent section, the source terms used in the equations employ a mathematical form which is independent of the boundary shape and of the boundary grid point distribution, the free parameters contained in the source terms are determined by the two restraint conditions, the intersection angle of transverse grid lines with boundaries and the local curvature of the transverse grid lines at the boundaries, and the interior grid distribution controlled directly by the grid point distribution assigned on the boundaries is realized, it makes the grid more clustering near the nozzle wall. For the generated grids in the whole computational regions have a good smoothness and orthogonality, the accuracy of calculation in the flowfield is ensured.

对轴对称的环形喷管采用控制网格面积的自适应网格方法对扩散段部分进行了网格生成,并通过非耦合方式应用于喷管的流场计算中;对强制偏流喷管扩散段内的三维区域采用椭圆型方程进行网格生成,方程中的源项采用了与边界形状和边界网格点分布无关的数学形式,源项内的自由参数由横向网格线与边界的交角及横向网格线在边界处的局部曲率两个约束条件来确定,实现了由边界上的网格分布直接控制内部的网格点,使壁面附近具有较密集的网格,并且在整个计算区域内的网格都具有良好的光滑性和正交性,从而保证了流场计算的准确性。
