During the procedure for searching K nearest neighbors of tested sample, the particle swarm move jumpily and randomly, and save largely the classification time. PSOKNN has the same classification performance as that of KNN classification algorithm.

PSOKNN算法在搜索K近邻的过程中，粒子群跳跃式移动，可以快速的找到测试样本的K个近邻，使得在保持K近邻法分类性能不变的情况下，分类的效率得到很大的提高。

As a result, it is convenient for the recognition system to use the simple linear classifier to segment the sample space, so that the accuracy and distortion invariant ability can be easily achieved. The classification structure of a bifurcating tree is utilized to decompose the classification problem of multi-classes to the multi-stage classification of two classes, which simplifies the design of the classifier, and improves the searching efficiency as well. A gray-scale analysis based method for extracting features from optical correlation result is proposed.

提出了二叉树鉴别分类方法，在使用同类图象的多个典型畸变样本训练识别系统的基础上，利用鉴别分析方法优化各类图象的特征向量在样本空间中的分布，不仅有利于同时提高系统的准确性和抗畸变能力，而且便于采用简单的线性分类器来划分样本空间；利用二叉树分类结构，将多类样本的分类问题分解为多级二类样本的分类问题，不仅简化了分类器的设计，而且提高了搜索效率。

A novel kind of Ordination-Fuzzy min-max neural network based on non-metric multidimensional scaling was proposed to solve the classification problems of unlabeled input pattern. Firstly, all the input patterns were sorted by MDS to get their similarity measures. Then these measures were used to supervise the following expansion and contraction stage of hyperboxes for classification. OFMM had improvements both in the validity of unlabelled patterns classification, and the network structure and training time.

该模型首先利用非刻度—多维度收缩法对输入的所有样本进行了排序，然后获得样本间的相似性测度值，并利用该相似性测度值指导随后的分类器超盒扩张与压缩过程，从而使得该模型不仅提高了对未标记样本进行有效分类的性能，而且无论是在网络结构方面，还是在训练时间方面都有所改进。

Although a certain correlation with the morphological classification based mainly on the characteristic of tubercles on the ripe fruit skin,the range of classification by RAPD was more detailed than that of morphological classification.

结果表明，大多数种质相似系数在55%～80%之间，说明他们之间的亲缘关系较近；在相似系数为0.61的水平上，30份海南荔枝种质被分为4组，与以龟裂片特征为主要分类依据的形态分类有一定的相关性，但是RAPD分类比形态分类的分类范围更细。

According to the Chinese Soil Taxonomic Classification(Revised Proposal, 1995)and our data and information for classification of Linze zone in the Hexi corridor, the authors propose a taxonomic classification of soils of Linze zone in the Hexi corridor, in which all the soils are divided into 4 soil orders(Anthrosols, Aridisols, Gleysols and Cambisols), 4 soil suborders , 5 soil groups and 8 soil subgroups.

文摘：根据《中国土壤系统分类》(1995)，对河西走廊临泽样区土壤进行了系统分类研究，提出了临泽样区土壤系统分类方案：将土壤分为4个土纲(人为土、干旱土、潜育土和雏形土)，4个亚纲，5个土类和8个亚类。

Chapter one is the semantic classification of speech act verbs. An overview of the semantic classification of general verbs and speech act verbs is described, and a further classification of speech act verbs is defined by means of semantic field theory and sememe analysis theory which includes Q-As, interactive, imperative, emotional, evaluative and declarative, etc. Chapter two is the analysis of the sememe analysis of Russian speech act verbs.

本章首先对国内外一般动词和言语行为动词的语义分类进行了研究综述，继而借助语义场理论和义素分析理论对言语行为动词进行了初步划分：问答类、交互类、祈使类、情感类、评价类和告知类；第二章汉、俄语言语行为动词的义素分析。

Botany》is composed of seed plant morphology anatomy and plant classification including spore plants classification and seed plant classification.

植物学》由种子植物形态解剖、植物分类（包括孢子植物分类和种子植物分类）两大部分组成。

The main purpose of this paper is to propose a unsupervised clustering-based method to pre-extract the support vector for training the SVM in light of the theory that the classification facet of SVM is determined by support vector only. By analyzing the limitation existed in current multi-class classification methods, and taking into account comprehensively the separability of the class set of nodes, a hierarchical classification method of SVM binary tree based on tree classifier with optimized overall performance is designed.
