Examples
- In the preprocessing stage the method of user and session identification often adopt heuristic algorithm for the being of cache and agent . this induce the uncertainty of data resource . the cppc algorithm avoid the limitation and has no use for complicated hash data structure . in this algorithm , by constructing a userld - url revelant matrix similar customer groups are discovered by measuring similarity between column vectors and relevant web pages are obtained by measuring similarity between row vectors ; frequent access paths can also be discovered by further processing of the latter . experiments show the effectiveness of the algorithm . in the fourth part , this thesis bring some key techniques of data mining into web usage mining , combine the characteristic of relation database design and implement a web usage mining system wlgms with function of visible . lt can provide the user with decision support , and has good practicability
本文算法避免了这个缺陷，且不需要复杂的hash数据结构，通过构造一个userid - uel关联矩阵，对列向量进行相似性分析得到相似客户群体，对行向量进行相似性度量获得相关web页面，对后者再进一步处理得到频繁访问路径。实验结果表明了算法的有效性。第四是本文将传统数据挖掘过程中的各种关键技术，引入到对web使用信息的挖掘活动中，结合关系数据库的特点设计并实现了一个具有可广西人学颀士学位论义视化功能的web使用挖掘系统wlgms 。 - Orthogonal matrixes have special structures , and every row vector of them can be taken as a plot , which may be parametrized in n - sphere space . through the research of structures of orthogonal matrixes , the writer finds a parametrized matrix , which can express all the orthogonal matrixes . through analysing uprightness between related high - order planes and the number of required parameters , we get the maturity of this method
自然的,这些点可以用其球坐标,即与各坐标轴的夹角来参数化,作者通过观察正交矩阵的几何结构,最终找到了任意维数的随机正交矩阵的参数表示方法,通过分析相关超平面之间的垂直关系和参数化正交矩阵需要的参数个数,论证了这种表示的完备性。 - In the subsystem of signal processing , digital sidelobe cancell block , digital pulse compress block , adaptive clutter canceller block , doppler filter and constant false alarm rate block are respectively discussed and set up . in signal processing , data in the same coherent processing interval form a matrix , and the data processing was completed based on the matrix . data are processed with the row vector or column vector respectively when needed
在信号处理分系统中，将脉冲压缩得到的数据在各个相干处理区间进行处理，将一个相干处理区间的数据按照不同的脉冲重复周期和不同的距离单元排列成一个矩阵，当需要实现数字脉冲压缩时对矩阵的各行(同一个脉冲重复周期的数据)进行处理，当需要实现多普勒滤波时，就对矩阵的各列(同一个距离单元的数据)进行处理。
