  1. The framework suppose that the image ' s semantic feature can be expressed by using a multi - level attribute tree, and the probability of a certain image having a certain attribute can be estimated by interpolation method using the neighboring image ' s value. here, the neighboring relation refers to the neighboring in the low - level feature space

    該框架假定圖像的語義特徵可用多層屬性樹來近似表示，並且圖像擁有某個屬性的概率值可由相鄰的圖像的概率值進行插值估計，框架中的相鄰指圖像在底層特徵空間的相鄰。
  2. The csbark algorithm computes the cs of an attribute according to the weighted feature difference and value difference, then searching the minimal reduction of attributes using cs as heuristic information. the cs value not only represents the importance of a condition attribute, but also reveals its relationships with other attributes. the minimal rules set algorithm depends on the value core and integrates the logic relation in the reasoning

    前者利用微差距離計算屬性的加權特徵差、利用互信息計算值差，從而求出各條件屬性的上下文敏感度，該值既反映了對應的條件屬性的重要性，同時還反映了該屬性與其它屬性的關聯程度；後者利用值核在生成規則過程中的重要作用，結合推理過程中的邏輯關系求解最小決策規則集，並給出了規則的評價指標支持度和信度的計算方法。
  3. Since analysis method of rough decision making based on extended dominance relation has its limitations, a new decision analysis method based on extension of the rough sets is proposed to multi - attribute decision making problems with preferential and incomplete information in this paper

    摘要針對基於擴展優勢關系的粗糙決策分析方法的局限性，本文給出了一種新的基於拓展粗糙集的多屬性決策分析方法。
  4. Based on substitution of the indiscernibility relation by a dominance relation and a confident threshold value a set, an extension of the rough sets model is proposed, which can deal with possible inconsistencies in preferential multiple attribute decision tables and obtain preferential probabilistic decision rules made up of preference actions

    摘要通過用優勢關系代替不可分辨關系，並設定置信閾值，提出了一種可以從偏好多屬性決策表中發現偏好概率規則集的擴展粗糙集模型。
  5. Considering that site selection is a multi - attribute decision with preference information, under the use of rough sets, the original decision table is replaced by the binary comparison table, the decision rules are reasoned by the dominance attributes sets, and then the ranking relation is obtained through these decision rules

    考慮到選址是一個具有偏好信息的多屬性決策問題，因此在粗糙集方法的使用中，用一個兩兩比較表代替原來的決策表，並通過優勢屬性集來推理決策規則，從而確定各方案排序。
  6. ( 4 ) it does not like the traditional method to suppose a special designated model concerns between well logging and seismic data. it gains a statistics relation from a series of data training and analysis, which _ is linear relation gained from multivariate regression or nonlinear relation gained from neural net training. ( 5 ) its most important characteristic is using the thought " alternation check " to evaluate the reliability of prediction, and can be used in the optimization of seismic attribute series

    這就允許我們用到迭前和迭后地震數據經過非線性變換的信息: （ 4 ）它不像傳統做法那樣在測井和地震之間假設一種特定的模擬關系，而是在對井點處一系列數據訓練和分析中獲得的一個統計關系，這個關系是通過多元回歸獲得的線性關系，或是通過神經網路訓練獲得的非線性關系: （ 5 ）它最重要的特點是利用「交互校驗」的概念來評估預測的可靠型，並能夠用於地震屬性系列的優化。
  7. After a brief description of concepts involved in the paper, such as rough set theory and the indiscernibility relation, the methods of how to preprocess the loss value of data and how to discrete the data are discussed. the algorithms of attribute < wp = 6 > reduction and value reduction in rough set theory are researched in depth, and then the ordinary reduction algorithms are given. the improved algorithms based on discernibility matrix and decision matrix are put forward

    論文在對所涉及的粗糙集理論以及不可分辨關系等概念進行了簡要的闡述后，接著對數據缺失值如何進行預處理以及如何進行數據的離散化處理等方法進行了探討，然後展開了對粗糙集理論中屬性約簡以及值約簡等演算法更進一步的研究，給出了常規約簡演算法，並在此基礎上提出了基於可辨識矩陣以及決策矩陣的改進演算法，結果表明演算法具有更高的約簡效果。
