  1. At the same time, a new decision - making method which determines the indices weight on the basis of the subjective preference and objective information entropy with the strict least square method as a tool is provided in the process of mcdm. with the development of worldwide shipping market, all kinds of special ship types and corresponding ship form evaluate alternatives are emerging. the traditional ( gb11697 - 89 ) method is only suitable for common ship types and it is not suitable for ocean floating structure system evaluation either

    傳統的國標法（ gb11697一89 ）只能對散貨船、集裝箱船、干貨和雜貨船、多用途船、油船和滾裝船等普通船型進行方案評價，也不能用於海洋工程中浮式結構物的系統論證，故採用gb11697一89針對上述特殊船型進行船型方案論證和技術經濟指標評價顯然已不能滿足實際工作需求和未來船型發展方向。
  2. This method utilizes an on - line algorithm based upon lssvm ( least square support vector machine ), which can build adaptive models to predict the cod values of unknown water samples quickly and accurately. in the modeling process, every training sample is also assigned a prior weight to take their significance to the final predictive model into account

    該方法是一種基於最小二乘支持向量機的在線自適應加權演算法，這種演算法可以自適應地選取和未知水樣最相近的標準樣本進行建模，同時在建模中又利用加權的方法分別考慮了各個標準樣本重要性。
  3. In first chapter, we define the first stage estimators for 0 and g by using kernel weight function, least square and two stage estimation under the additivity of the model, and then the paper proves that is the consistency and the approximate normal distribution, and is the consistency and the uniform consistency

    第一章首先綜合核函數法，最小二乘法，基於模型的可加性，利用二階段估計的方法求出， g的第一階段估計量，然後證明了的強相合性與漸近正態性， g _ n ~ *的強相合性和一致強相合性。
  4. Further more, with the knowledge of the relations between new and old samples, the article put forward the iteration algorithm of the weight in ordered samples " weighted least - square estimation, the model if good at forecasting

    其次，在新樣品與原樣品的關系確知的情況下，該文提出了有序樣品的加權估計中權重的一種迭代取法，再進行新預測，效果顯著。
  5. For h - d scattered data, local weighted least - squares fitting ( llsf ) methods for approximation and interpolation are respectively put forward and the latter is got by adjusting weight function in the former case, and the interpolating method is also used to construct hyper - surface models with the radial function. the problem of choosing weight function during local least square approximation is discussed and two good weight functions are given : one with a parameter, the other with no parameter. based on them

    二、對非規則區域上分佈的h - d數據，提出了散亂數據超曲面擬合的局部最小二乘逼近法。通過對局部最小二乘逼近的權因子作適當的改進，得到了擬合精度較高的局部最小二乘插值法，還用徑向基函數構造了超曲面模型，找到了一種性質好帶參數的權函數以及另一種有著普遍精度性質的不含參數的權函數，獲得了較好的逼近效果。
  6. Fuzzy c - means algorithm is used to cluster the production data in batch annealing process, then the exponent least square algorithm is used to get the relationship between cooling time and weight of clusters

    採用模糊c均值聚類方法對退火生產數據進行處理，再基於得到的聚類數據點進行指數最小二乘回歸。
  7. Furthermore, from the viewpoint of hydrological application, the types and characteristic of rainfall observation error in hydrological remote system are analyzed and a three - stepwise weight function correction method of the error in the system is developed on the basis of theory of robustified least square method

    然後根據遙測系統雨量觀測資料誤差的類型和特點，結合抗差最小二乘法，提出了雨量觀測資料誤差三步權函數修正方法。每一步均利用雨量資料誤差的不同特點，提出不同的權函數進行修正。
