Compared with the classical bp algorithm, robust adaptive bp algorithm possesses some advantages as following : ( 1 ) increasing the accuracy of the network training by means of using both the relative and absolute residual to adjust the weight values ; ( 2 ) improve the robustness and the network convergence rate through combining with the robust statistic technique by way of judging the values of the samples " relative residual to establish the energy function so that can suppress the effect on network training because of the samples with high noise disturbances ; ( 3 ) prevent entrapping into the local minima area and obtain the global optimal result owing to setting the learning rate to be the function of the errors and the error gradients when network is trained. the learning rate of the weights update change with the error values of the network adaptively so that can easily get rid of the disadvantage of the classical bp algorithm that is liable to entrap into the local minima areas
與基本bp演算法相比，本文提出的魯棒自適應bp演算法具有以下優點： （ 1 ）與魯棒統計技術相結合，通過訓練樣本相對偏差的大小，確定不同訓練樣本對能量函數的貢獻，來抑制含高噪聲干擾樣本對網路訓練的不良影響，從而增強訓練的魯棒性，提高網路訓練的收斂速度； （ 2 ）採用相對偏差和絕對偏差兩種偏差形式對權值進行調整，提高了網路的訓練精度； （ 3 ）在採用梯度下降演算法對權值進行調整的基礎上，通過將學習速率設為訓練誤差及誤差梯度的特殊函數，使學習速率依賴于網路訓練時誤差瞬時的變化而自適應的改變，從而可以克服基本bp演算法容易陷入局部極小區域的弊端，使訓練過程能夠很快的「跳出」局部極小區域而達到全局最優。 -
For the methods based on constraint residual, they can be used to only tell which node is imbalance but cannot identify where the gross error is. in order to avoid these problems, this thesis proposed a new test method. the new method combines an f - statistic with constraint residual statistic to detect gross errors in steady state processes
這種方法即避免了基於測量殘差的檢測方法會將顯著誤差分散到各個測量值中去的缺陷；又避免了基於約束殘差的檢測方法只能對節點的平衡性進行判斷，而無法確定顯著誤差的具體發生位置的缺陷。 -
The solution formula of dwell time is deduced by using the pulse iteration method and the smoothing fourier transition method, and the formula can be simplified referring to workpiece shape. according to the anastomotic status of the tool and workpiece surface, we present the new model of the inherent relation among local pressure density, removal rate, convergence ratio and residual errors, and the corresponding formulas are given. the forming cause of the edge effect in the polishing process is analyzed, and the means which reduces the edge effect is put forward
2 、針對計算機控制光學表面成形（ ccos ）的加工方式、誤差收斂特點，研製了去除函數呈高斯分佈的雙轉子結構研拋模；採用脈沖迭代法、平滑因子傅立葉變換法推導出駐留時間的演算法，求解過程中根據工件面形的特點作了各種形式的簡化；提出了工件表面和研拋模的吻合誤差與局部壓強、材料去除率、收斂比之間內在關系的數學模型，並推導出相應的計算公式；分析了邊緣效應產生的原因，在加工過程中採用相對壓力因子對去除函數進行修正，可以消除邊緣效應的影響。 -
The relationship between gdp and export of the prc ’ s province, cities, and autonomous regions is analysed in panel data set : gdp and export annul datafrom 1992 to 2004 in the prc ’ s province, cities, and autonomous regions. empiricalanalysis show that the fixed two panel model is better than other model, but exist theproblem of residual errors sequence correlation
同時利用中國內地省區市1992年至2004年的年度國內生產總值與對外出口貿易總額的面板數據做了大量實證分析，發現雙向固定效應模型比較適合此面板數據集，但是存在殘差序列相關的問題。 -
For the existing test based on measurement residual, the main problem is that the data reconciliation procedure tends to spread the gross errors overall the measurements, which results in the detection failure
通過構造一個基於測量值比例關系的f統計量，並與約束殘差統計量相結合，對穩態過程中出現的顯著誤差進行檢測。
