At first,the negative data is divided into several parts accumulatively according to the geometric distribution of the training data.

该方法首先根据样本的几何分布，用迭代的方式把负样本分成若干部分与正样本线性可分的样本；然后用L-SVM对这些正负样本进行分类，得到若干个线性分类器；最后，将这些线性分类器顺次组合，构成级联分类器。

There are different opinions of the taxonomy on the subfamily, tribe, genus and species of Umbelliferae because the taxonomic system of Umbelliferae is based on the typical umbrella anthotaxy and its fruit with specific secretory tube.

但是由于伞形科的分类系统是建立在典型的伞形花序和带有特殊分泌管的果实的基础之上的，使得分类学者在亚科、族、属和种的设立和分类方面存在分歧，实验主要针对阿魏属和独活属的花粉形状进行研究，对阿魏属和独活属植物的分类提供一些基础数据。

There are different opinions of the taxonomy on the subfamily, tribe, genus and species of Umbelliferae because the taxonomic system of Umbelliferae is based on the typical umbrella anthotaxy and its fruit with specific secretory tube. The pollen morphology is carefully observed in this test in order to provide several basic data for the taxa of Ferula and Heracleum.

但是由于伞形科的分类系统是建立在典型的伞形花序和带有特殊分泌管的果实的基础之上的，使得分类学者在亚科、族、属和种的设立和分类方面存在分歧，实验主要针对阿魏属和独活属的花粉形状进行研究，对阿魏属和独活属植物的分类提供一些基础数据。

One of the classification models that based on statistic theory is Bayesian network classifier.

目前已知的分类算法中一种重要的基于统计方法的模型是贝叶斯分类模型，在贝叶斯分类模型中实用性最高和应用最广泛的是朴素贝叶斯分类器。

The latter seems to be more reasonable in designing in terms of evenness values.

在两种分类系统中也存在一些细小的差别，垫刃亚目分类体系较中国土壤系统分类具有更丰富的分支体系，而从均匀度指数来看，中国土壤系统分类系统的设计似乎是更加合理。

This classfier extracts the feature vector of each samples and documents to be classified by using the feature extraction algorithm. Web page was classfied by using the K-Nearest-Neighbor classification algorithm. The experimental results show that this auto classifier based on Web minning can fetch insecurity Web pages, and its classification is effective.

该自动分类器利用特征提取算法实现对每个样本的特征向量提取和待分类文本的特征向量提取，利用基于k个&最近邻&分类算法实现对网页的分类，能够提取出带有不安全信息的网页，分类效果良好。

By means of the novelly decoded manner and the well constructed fitting function, the global searching performance for the GA is developed so that optimized RBPNN approaches to the parsimonious structure;(4) A ROLS micro-genetic algorithm was built by integrating the micro-genetic algorithm with good convergence performance based on tiny class of group with the ROLS-SOA.

提出一种新的基于径向基概率神经网络的模式识别融合系统，即多分类器系统，避免了单一径向基概率神经网络分类器的分类局限性，减少了寻求单一分类单元结构最优化时的计算复杂度，通过使用D-S融合算法，大大提高了对复杂模式识别问题的分类精度。

This paper reviewed the polyphasic taxonomy of acetic acid bacteria, mainly introduced the current classification of acetic acid bacteria, then discussed the application of phenotypic, chemotaxonomic and genotypic method in the taxonomy of acetic acid bacteria.

本文综述了醋酸菌的多相分类研究进展，主要介绍了醋酸菌的现行分类情况及表型分类、化学分类和基因分型等方法在醋酸菌分类中的应用。

But since its advent, scores of taxonomists have decried the shortcut, claiming it will undermine the purposely elaborate systems developed to ensure ID precision and accuracy.

但是这种分类方法的使用也遭到了许多分类学者的诋毁，他们认为这种分类方法严重破坏了现有精细的分类体系，使得分类的准确度大大降低。

The article introduces classification theory, concept, types of classification schemes and schemes of classification theory, that include three types: hierarchical classification, for example Dewey Decimal Classification; enumerate classification, for example Library of Congress of Classification

本文旨在介绍分类理论、分类法术语与概念、分类表的类型，各分类表的分类理论，并从三种不同型式，包括：阶层式的杜威十进分类法；列举式的美国国会分类法；层面式的国际十进分类法、书目分类法、冒号分类法，并预测未来分类理论及分类法的发展与趋势。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
