查询词典 hierarchical classification

To be more economic, this paper presents a new hierarchical automatic classification on Chinese texts, with some improvements on term weighting and reduction of dimensionality as wel

因此本论文在对自动分类技术进行深入研究的基础上，结合实验室原有的单层次的分类成果，实现了一个多层次的中文文本自动分类系统，并在特征加权和维数缩减方面等方面做了一定改进。

It's obvious that semantic retrieval is more reasonable than retrieval based on low features. So we need to study image retrieval based on region segmentation, image hierarchical classification and image semantic label standard.

显然语义级检索是比基于低层特征检索更合理的图像检索方法，因此有必要研究基于区域分割的图像检索、基于语义级的图像分级分类和图像的语义标记标准。

An integrated hierarchical matching method based on classification management of the road network is firstly proposed considering the different characteristics of urban roads. This method is conducive to use different matching algorithm according to both different road condition and navigation demand, and can better coordinate contradictions between the accuracy and real time of matching.

在改进现有地图匹配算法的基础上，针对城市道路的不同特点，首次提出基于道路网分级管理的分级匹配综合方法，有利于根据不同的路况和导航需求采用不同的匹配算法，可较好地协调地图匹配的准确性和实时性的矛盾。

In this paper,the algorithm of a kind of hierarchical competitive covering networks for the classification problems is proposed based on the introduction of quotient space theory,which defines granularity according to Huffman coding and Huffman coding algorithm.

文中在此基础上，利用商空间的粒度原理和霍夫曼编码的思想，对样本分布极其不均匀的分类问题，构造分层竞争覆盖网络。

Secondly, the method of hierarchical classification was adopted to divide 282 cities into 3 kinds, the first was mainly capital cities and vice-province cities; the second was mostly eastern coastal cities and some middle cities; the third was western cities and part of middle cities. Thirdly, principle component analysis was taken to get the numbers of principle component, dedicative ratios of each principle component, and indicator values of each kind of cities, then, the differences of numbers of principle component, dedicative ratios of each principle component, and indicator values of each kind was investigated.

然后采用层次聚类分析的方法将282个地级城市分成了3类，采用主成分分析的方法分别对每一类型城市进行分析，得出每类型城市主成分的组数、每组主成分的贡献率及指标的因子值，分析了各类型城市主成分及指标因子值的差异。

Formly, HDR casts classification problems and regression problems into a unified regression problem. Clustering is performed in both output space and input space at each internal node, termed "doubly clustered" and discriminants in the input space are automatically derived from the clusters in the input space. A hierarchical probability distribution model is applied to the resulting discriminating subspace at each internal node.

在图像的分类和检索中，以前的层次判别回归方法把分类和回归统一成回归问题，在每个内部节点进行输入和输出空间的双聚类，输入空间的分类子空间可以自动从聚类中获得，再用层次概率分布模型计算判别子空间，这样就构成了输入空间由粗到精的概率分布，可以准确而且快速地实现高维数据的检索。

However, the present available methods of applying LSI to text classification are not satisfying, since they do not take full account of classification information.

但目前文本分类中使用LSI方法的效果并不理想，这是因为没有充分考虑分类信息。

Based on physical properties, mineral composition, chemical components and infrared spectra, the main mineral components of "Kunjiu Jade" and "California Jade" are proved to be tremolite and actinolite respectively. Both Jades belong to nephrite in gem classification and ultrabasic rock in mineral deposit classification.

根据加里福尼亚州的"加州玉"和缅甸"困就"的物理性质，矿物组成、化学成分及红外光谱特徵，确定"困就"的主要矿物成分是透闪石，"加州玉"的主要矿物成分为阳起石，两者的宝石名称是软玉。

According to the different functions of the central government and local governments in the economic and social activities, the rights of affaire administration are classified between the central government and local governments; and the classification of the expenditure between the central government and local governments are made on the basis of the classification of the rights of affairs administration between them.

指根据政府在经济和社会活动中的不同职责，划分中央和地方政府的责权，按照政府的责权划确定的支出。
