row vector造句
例句與造句
- 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
本文算法避免了這個缺陷,且不需要復雜的hash數(shù)據(jù)結(jié)構(gòu),通過構(gòu)造一個userid - uel關(guān)聯(lián)矩陣,對列向量進行相似性分析得到相似客戶群體,對行向量進行相似性度量獲得相關(guān)web頁面,對后者再進一步處理得到頻繁訪問路徑。實驗結(jié)果表明了算法的有效性。第四是本文將傳統(tǒng)數(shù)據(jù)挖掘過程中的各種關(guān)鍵技術(shù),引入到對web使用信息的挖掘活動中,結(jié)合關(guān)系數(shù)據(jù)庫的特點設(shè)計并實現(xiàn)了一個具有可廣西人學頎士學位論義視化功能的web使用挖掘系統(tǒng)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,這些點可以用其球坐標,即與各坐標軸的夾角來參數(shù)化,作者通過觀察正交矩陣的幾何結(jié)構(gòu),最終找到了任意維數(shù)的隨機正交矩陣的參數(shù)表示方法,通過分析相關(guān)超平面之間的垂直關(guān)系和參數(shù)化正交矩陣需要的參數(shù)個數(shù),論證了這種表示的完備性。 - 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
在信號處理分系統(tǒng)中,將脈沖壓縮得到的數(shù)據(jù)在各個相干處理區(qū)間進行處理,將一個相干處理區(qū)間的數(shù)據(jù)按照不同的脈沖重復周期和不同的距離單元排列成一個矩陣,當需要實現(xiàn)數(shù)字脈沖壓縮時對矩陣的各行(同一個脈沖重復周期的數(shù)據(jù))進行處理,當需要實現(xiàn)多普勒濾波時,就對矩陣的各列(同一個距離單元的數(shù)據(jù))進行處理。 - It's difficult to find row vector in a sentence. 用row vector造句挺難的
