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.

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。
