分类的

Results showed that this method could classify pests effectively, and showed higher classification accuracy and better understandability than BP neural network.

结果表明，该方法能有效地对害虫进行分类，比BP神经网络分类精确度高、分类结果的可解释性更好。

Firstly, the target vector is transformed to the state with minimization of cross-polarization; then the parameters u/v/H are used to characterized scattering mechanism, and the fuzzy membership is adopted instead of "hard" division of parameter plan; finally, characterizing the coherency matrix as multivariable complex Wishart distribution, the polarimetric SAR image is classified based on Bayes maximum likelihood criteria.

该文提出了一种新的非监督分类算法，该算法首先根据去取向理论，将目标向量旋转到最小交叉极化方向；然后，采用u/v/H参数描述散射机制，以模糊隶属函数代替参数平面的"硬"阈值划分；最后，以多元复Wishart分布描述相干矩阵，基于Bayes极大似然分类准则进行分类。

In the zoological classification, the lowest-ranking group of taxa the names of which are regulated by the Code.

在动物分类中，其名称受本规约规范而分类层级最低的分类单元群。

And then it combined binary tree with LS-WSVM, so that the LS-WSVM multi-class classification model based on binary tree was proposed. The model not only avoids the condition of blind classification and impartibility, but also improves classification speed and generalization ability.

然后，把二叉树结构和LS-WSVM相结合，提出了基于二叉树的LS-WSVM多类分类模型，不仅避免了盲目分类和不可分情况，而且提高了分类速度和泛化能力。

A taxon or assemblage of taxa; e.g. the taxonomic group Insecta consists of all insects and the taxa in which they are classified.

一个分类单元或一组分类单元；例如昆虫纲这个分类群包含全部昆虫以及被列入的各个分类单元。

In the Subtotals dialog, in the Group by box, select the column that you want to add the subtotals to.

在分类汇总对话框的分类依据框里选择要添加分类汇总的列。

The simulation for the multi-component linear frequency-modulated signals demonstrates the improvement of classification performance compared with time-frequency analysis only.

以分类误差最小为目标，自适应调整支撑矢量核和时频表示核的参数，并对SAR运动目标回波模型——线性调频信号进行仿真实验，实验结果表明这一方法提高了分类精度，改善了分类性能。
