In the algorithm level, currently various training algorithms of neural networks, including gradient algorithms, intelligent learning algorithms and hybrid algorithms, are comparatively studied ; the optimization principle of bp algorithm for neural networks training is analyzed in detail, and the reasons for serious disadvantages of bp algorithms are found out, moreover, the optimization principle of two kinds of improved bp algorithms is described in a uniform theoretic framework ; and the global optimization algorithms of neural networks, mainly genetic algorithm are expounded in detail, it follows that a improved genetic algorithm is proposed ; finally the training performances of various algorithms are compared based on a simulation experiment on a benchmark problem of neural network learning, furthermore, a viewpoint that genetic algorithm is subject to " curse of dimension " is proposed
在演算法層，本文對目前用於神經網路訓練的各種演算法，包括梯度演算法、智能學習演算法和混合學習演算法進行了比較研究；對用於神經網路訓練的bp演算法的優化原理進行了詳細的理論分析，找到了bp演算法存在嚴重缺陷的原因，並對其兩類改進演算法-啟發式演算法和二次梯度演算法的優化原理，在統一的框架之下進行了詳盡的理論描述；對神經網路全局優化演算法主要是遺傳演算法進行了詳細的闡述，並在此基礎上，設計了一種性能改進的遺傳演算法；最後基於神經網路學習的benchmark問題對各種演算法在網路訓練中的應用性能進行了模擬研究，並提出了遺傳演算法受困於「維數災難」的觀點。Based on traditional derivative theories of commercial banks to operate internationally, retrospect of international development of overseas banks ’ international operation, combined with international operation history and current situation of our country ’ s state - owned banks, this paper puts forward strategies for international operation, that is, conducting a perfect market access study of targeted country, advancing ladder likely in term of territory, following the prescribed order in terms of organizing means, improving in proper sequence in terms of product strategy, this paper puts forward to construct internal risk control system and strengthen home country ’ s regulation on overseas institutions, advance process of commercial banks ’ international operation
隨著我國加入wto 「后過渡期」的日益臨近，佔有我國金融絕對比重的國有商業銀行必然要面對與國際金融市場融合的新形勢，實施國際化經營。本文在闡述商業銀行跨國經營的傳統成因理論的基礎上，回顧海外銀行業國際化發展的歷史，結合我國國有商業銀行當前現狀，提出了國際化經營策略，即做好東道國市場準入研究，在地域上梯次推進，組織方式上按部就班，產品策略上循序漸進，以期解決在哪裡經A recent questionnaire survey and analysis organized and conducted by us shows that the undergraduate teaching administration of jiangsu university at present should focus on the conformity and optimizing of academic subjects, make effort to reinforce the full - time staff construction mainly with the echelon construction of academic subjects, enhance in an all - round way the training of undergraduates ' learning capability and technical ability of experiment and practice, put emphasis on bilingual teaching, give full play to the supporting function of the resources available such as library books for teaching, give a vigorous impetus to the innovation of administration system, hence to realize the second leap of the level of undergraduate teaching administration of jiangsu university
作者根據教育部本科教學水平評估指標體系，組織了一次問卷調查，結果顯示當前學校本科教學工作應集中精力整合和優化學科結構，著力加強以學科梯隊構建為主線的專任教師隊伍建設，全面加強學生學習能力培養和實驗實習技能訓練，重視雙語教學，充分發揮圖書信息等資源對教學工作的支撐作用，積極推進管理制度創新，以此實現學校本科教學工作水平的二次飛躍。An old woman has lived in one - story house before. her body is very short. afterwards, she moves into a big building and lives in the ninth story
有位老婦人，從前住平房，並且個子非常矮，后來她搬進了一個很高的樓里，住在第九層，但是她每次回家，她總是乘電梯到第六層就下來，然後走到第九層.為什麼Following are detailed steps of this system : in the segmentation section, we use three successive frames to detect the motion infomation of the pictures, by using blockmatching algorithm in two successive frames twice, we can get two pictures composed of motion blocks of the moving object, then we find out the common motion blocks of the two pictures, experiments prove these blocks approximately compose the moving object. after getting the motion blocks, we calculate the center of these blocks as the center of the moving object, thus we can use the center point as the origin, construct n straight linesjoining the boundry of the image and the center. on each line, we can find out a proper point near the object contour according to some criteria, then we use these n points as the initial points of the snake and let the snake converge on the object contour, thus finish the segmentation of the moving object
本方案的實現過程為：分割部分：對運動目標的前後三幀進行兩次塊匹配運動檢測，通過找出兩個匹配結果中運動圖像塊的公共部分，獲得組成運動目標的圖像塊；求出運動目標圖像塊的形心作為運動目標的中心，以此中心為端點，向四周發散出角度間隔為的n條射線，射線的另一端終止於圖像的邊緣；在每條射線上按照一定的準則（點的梯度和與目標中心的距離在一定閾值范圍內）找出n個初始輪廓點；以這些初始輪廓點作為主動輪廓模型（ snake ）的初始點，用改進的貪婪演算法使snake收斂到待分割的運動目標輪廓上。分享友人
