向量函数

In this paper, the image intensity surface for the neighborhood of every pixel is well-fitted by the Least Squares Support Vector Machine, and the gradient and the zero-crossing operators are deduced from the LSSVM with the Radial Basis Function kernel function, as an example.

摘要该文利用最小二乘向量机对原始图像每一像素的邻域作灰度曲面的最佳拟合，并以径向基核函数为例导出了图像的梯度算子和零交叉算子。

This method first maps training data into a high dimensional feature space through kernel function concept in Support Vector Machine and constructs orthogonal space in the feature space. Then it maps the data from feature space into the orthogonal space and computes Fisher criterion based global orthogonal discriminants.

首先应用支持向量机中核函数的概念，将样本隐式地映射到特征空间，然后构造特征空间的正交空间，再将特征空间样本映射到特征空间的正交空间，求解基于Fisher的全局正交鉴别矢量集。

In addition, since the channel frequency response is usually oversampled by the pilot sub-carriers, the channel power will be concentrated to a relatively small number of samples in the effective channel impulse response vector.

这种情况下，如果在进行基于DFT的内插之前，我们不用一个窗函数对观测到的信道频率响应向量进行加窗处理，则内插后，由能量泄漏而引起的混叠现象将导致信道估计的错误平底。

The universal expression of Laue equation and two theorems on reciprocal space and reciprocal vector are obtained and proved.

讨论和研究了干涉函数对衍射的影响，提出并证明了Laue方程的一般表达式和有关倒易空间与倒易向量的2个定理，研究了作为三维晶体特例的二维晶体的衍射，讨论了二维晶体倒易点阵的物理内容和点阵点的权重。

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。
