Then the parameter group and identifmbility criterions were discussed . the identification algorithm based on the simulated annealing - simplex shape algorithm was proposed 對(duì)基于靜力位移結(jié)構(gòu)識(shí)別問(wèn)題的參數(shù)分組及可辨識(shí)性標(biāo)準(zhǔn)進(jìn)行了討論,建立了基于模擬退火-單純形的完全非線性識(shí)別算法。
To make up the shortages in practice of that network , the thesis synthetically exerts the principal components analysis clustering analysis and fuzzy c - means to offer the initial training samples for the network , then makes use of the genetic algorithm to find the best parameters group , in the end of this thesis , as an example , evaluates the credit grades of the 57 pieces of customers of a domes tic pharmaceutical group , giving out each customer ' s credit grade and the degree belonging to that grade as basis for the enterprises to investigate the credit status and determinate the quota 為克服該網(wǎng)絡(luò)實(shí)用中的不足,綜合運(yùn)用主成份分析( pca ) 、聚類分析和模糊c -均值( fcm )等方法,為該網(wǎng)絡(luò)提供初始訓(xùn)練樣本,并采用遺傳算法對(duì)該網(wǎng)絡(luò)關(guān)鍵參數(shù)組合進(jìn)行尋優(yōu)。最后以國(guó)內(nèi)某制藥集團(tuán)57份客戶信用評(píng)分結(jié)果為例,進(jìn)行應(yīng)用分析,給出每個(gè)客戶的信用等級(jí)和對(duì)該等級(jí)的隸屬度,作為企業(yè)審查客戶信用水平、確定信用限額的依據(jù)。
In the fourth part , by using the bifurcation theory of planar dynamical systems and the method of detection functions , the paper gives a configuration of limit cycles forming compound eyes . with the help of numerical analysis ( usi ng maple ) , it is shown that there exist parameter groups such that a z7 - equivariant planar polynomial vector field of degree 7 has at least 36 limit cycles with z7 - symmetry 然后,對(duì)于一組特定的參數(shù)值,研究了它的相軌線的變化趨勢(shì);第四部分指出:在一定的條件下,利用平面動(dòng)力系統(tǒng)分支理論以及判定函數(shù)法,在計(jì)算機(jī)數(shù)學(xué)軟件( maple )的幫助下,得到結(jié)論: 7次z _ 7 -等變平面向量場(chǎng)至少有36個(gè)極限環(huán),形成具有z _ 7 ?對(duì)稱性的極限環(huán)分布。
