维数

Such technique pursues,through the study of the eigenvalues, the reduction of the dimensionality in the representation space.

这种方法是通过对特征值的研究，追求表征空间的维数压缩。

So, we can try to discover the relationship between riverway 's fractal dimension and river flood, and find a quantitative index to help establish some strategies of controlling river flood.

因此，我们可以通过研究黄河下游河道分形维数与洪水之间的关系，找出二者间的关联，为制定防洪决策提供定量化的参考指标。

In the research, 28 characters including energy, informationization measure, fractal dimension, hue, cb, color moment, disease spot area, rotundity, figure factor, and others were extracted, and four approximate features were selected from 28 primordial features. The results indicated that the precision of the three kinds of maize disease recognition was higher than 90%.

研究中提取了墒、相关信息测度、分形维数、H值、Cb值、颜色矩、病斑面积、圆度、形状因子等28个特征向量，利用遗传算法优选出H值、颜色矩、病斑面积、形状因子等4个独立、稳定性好、分类能力强的特征向量，应用费歇尔判别分析法识别病害，准确率达到90%以上。

This is a matrix that causes no effect when it's concatenated with another matrix of the same dimensions.

单位矩阵在和另一个相同维数的矩阵连接时没有任何效果。

Identify a line 4 5 2-D array of "saddle point," that is the position of the element in the largest firms, out of the...

找出一个4行5列的二维数组的"鞍点"，即该位置上的元素在该行上最大，在该列上最小。

Identify a line 4 5 2-D array of "saddle point," that is the position of the element in the largest firms,...

找出一个4行5列的二维数组的"鞍点"，即该位置上的元素在该行上最大，在该列上最小。

This is a judgment of the saddle point algorithms, user input when a two-dimensional array, When one element per...

这是一个判断马鞍点的算法，当用户输入一个二维数组，当一个元素为每行的最小，而又是每列的最大时，它就是马鞍点！

The algorithm reduces the dimension of the input vectors by using the Toeplitz technique for the sample correlation matrix and needs only the first column of the processed matrix.

该算法仅将Toeplitz化后的采样协方差矩阵的第一列元素作为网络输入，从而降低了输入矢量的维数。

Based on this information and the method of fuzzy identification, fuzzy belonging-functions and equations are derived for the low porosity and low permeability reservoirs of Silurian in the block.

根据毛管压力曲线和相对渗透率的分形几何公式计算孔隙的分维数；以储层测井信息所反应的储层地质特性为基础，利用模糊识别方法，建立了该区块志留系低孔渗储层测井信息的模糊隶属函数和隶属方程；所得隶属度的大小可以用来判断储层的所属类型。

The matching method based on wavelet transformation measures the similarity by using the distance standard at some resolution level.

新方法在某一分辨级水平上进行曲线形状相似性查询和度量的同时也进行维数曲线的度量和匹配。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
