So in order to solve this problem, we not only use variable precision rough set and ameliorate the arithmetic-reduced used in traditional Rough Set, but also describe this uncertain decision information with weight support and confidence of classing rule.

为了解决这个问题，本文采用了可变精度粗糙集模型，并对传统粗糙集的一种属性约简算法作了改进，以适用于可变精度粗糙集模型，最后引入加权关联规则中的加权支持度和可信度来描述不确定性信息。

Eight 3×3 Kirsch direction templates are convoluted with a SAR image respectively and the maximum of convoluting results is used as the edge strength value of the central pixel in the window. The output gray level of the central pixel is the weighted average of gray levels of its eight neighboring pixels, and the weighting coefficients are corresponding edge strength values.

该方法利用8个3×3的Kirsch方向模板分别与SAR图像进行卷积运算，取其中的最大值作为窗口中心像素的边缘强度值，中心像素灰度值的滤波输出为它的8个邻域像素灰度值的加权平均，加权系数为每个像素的边缘强度值。

In EC - Bed Linen the Appellate Body examined the first method under Article 2.4.2 for establishing the existence of margins of dumping, i.e. the comparison of a weighted average normal value with a weighted average of prices of all comparable export transactions.

在EC - Bed Linen案中，上诉机构认为，2.4.2条规定的确立倾销幅度存在与否的第一个方法，即对正常价值的加权平均值与全部可比性的出口贸易的加权平均价格进行比较。

As feature extraction acts an important role in pattern recognition system, we propose three novel feature extraction methods for HCCR: a、Two structural feature extraction methods, Stroke Cross Counting Features and Peripheral Features are studied. According to the characteristics of Chinese handwriting samples, we extend the SCCF and PF respectively to weighted elastic SCCF and weighted elastic PF. Experiments show that the modified feature extraction approaches are better than original approaches. b、A new statistical feature extraction method——Elastic Meshing Directional Decomposition Feature extraction is proposed. According to the stroke statistical properties of Chinese character, we first decompose a handwritten character pattern into four directional subpatterns. Then a set of elastic meshes are applied to each of the four subpatterns respectively to extract the pixel distribution features.

统计识别方法：利用统计模式识别的经典方法——Bayes分类方法来进行汉字识别的研究，特征提取是统计模式识别的关键，本文着重围绕手写体汉字的特征分析和提取方法进行了研究，提出了三种特征提取的新方法： a、两种改进的结构特征提取方法：在笔划密度特征和外围特征的基础上，结合手写体汉字的特点，提出了加权非均匀笔划密度特征、加权非均匀外围特征的特征提取新方案； b、一种新的统计特征提取方法——弹性网格方向分解特征，根据汉字方块字的特点及笔划分布的统计特征，对手写体汉字进行横竖撇捺四方向的分解，并利用一系列的弹性网格对汉字分解后各分量的象素进行统计而提取特征，实验证明该特征提取方法用来进行手写体汉字识别是十分可行和有效的。

Further, value-weighted portfolio-matching approaches are better specified and more powerful than equal-weighted approaches.
