分类空间

High dimensionality is one of the main problems in text categorization.

文本分类中特征空间的高维问题是文本分类的主要障碍之一。

Based on the methods and techniques of covering theory, the structure of module category of tame concealed algebra, one-point extension, vector space category, finite enlargement, degeneration theory, stable equivalence and combinatorial method, we will classify all of the three-point algebras with Gabriel quiver the system quiver Q according to representation type. We get the classification theorem: Let A=kQ/I be a three-point algebra given by the system quiver Q.

The second chapter analyzed its phylogeny, contrasted and classified the conformation in terms of the ancient period of external and internal and the modern times. The third chapter concluded the mainstream trend of transformation in contemporary days and sum up the character. Proceed with the basic patterns, the fourth chapter discussed the skills and technique of entrance space design concretely and practically. From the point of environment theory, the last chapter studied its meaning and function to surrounding quality, further advanced the ingression from a architectural element to a broad conception in city design.Combined with excellent examples of famous architect home and abroad, this thesis push forward its research to the skills and techniques of entrance space design.

In this paper, we give explicit constructions and formulations for harmonic maps from R1,1 into classical real semisimple Lie groups by using Darboux transformation. We also discuss pluriharmonic maps from complex manifoldsinto symmetric spaces and Willmore surfaces in Sn. By converting geometric conditions satisfied by these maps into integrable systems, and using the the-ory of integrable systems, we give explicit constructions for pluriharmonic maps from complex manifolds into symmetric spaces and the Willmore surfaces in Sn respectively. Finally, we classify hypersurfaces in Sn+1 with three distinct prin-ciple curvatures and zero Mobius form using the theory of Mobius geometry. The paper consists of four chapters.

本文首先利用Darboux变换的方法给出了从Lorentz平面R~(1，1)到经典实半单Lie群的调和映照的具体构造，并给出其显式表示；其次研究了复流形到对称空间的多重调和映照及球空间S~n中Willmore曲面，将这些映照所满足的几何条件转化为可积系统，然后利用可积系统理论分别给出复流形到对称空间的多重调和映照与S~n中Willmore曲面的构造；最后利用Mōbius几何的理论给出S~(n+1)中具有三个不同主曲率且Mōbius形式为零的超曲面的分类。

The method uses techniques such as document space transforming and principal component analysis to map original document vector in very-high-dimension term space to low-dimension principal component space, and then categorizes documents by comparing them to the centroid of each category.

该方法采用了文档空间变换和主成分分析技术，将文档的原始矢量表示从高维词条空间映射到低维主成分空间，并利用文档类别重心进行分类。

The SVM has the basis limited sample training to obtain good exude ability,and it\'s an general learning machine,it maps the original space into high dimensional characteristic space,makes the original classified question become a linear separable question in the characteristic space.

支持向量机具有依据有限样本训练获得良好的泛化能力，并且是一个通用的学习机，它将原空间映射到一个高维的特征空间里，使原分类问题在特征空间里成为一个线性可分的问题。

In this framework, image frame, audio and text are represented, which are the three modalities in video shots as data points by the 3rd-order tensor. Then a subspace embedding and dimension reduction method is proposed, which explicitly considers the manifold structure of the tensor space from temporal-sequenced associated co-occurring multimodal media data in video. It is called TensorShot approach. Transductive learning uses a large amount of unlabeled data together with the labeled data to build better classifiers. A transductive support tensor machines algorithm is proposed to train effective classifier. This algorithm preserves the intrinsic structure of the submanifold where tensorshots are sampled, and is also able to map out-of-sample data points directly. Moreover, the utilization of unlabeled data improves classification ability.

在此框架中，视频镜头首先被表示成由视频中所包含的文本、视觉和听觉等多模态数据构成的三阶张量；其次，基于此三阶张量表达及视频的时序关联共生特性设计了一种子空间嵌入降维方法，称为张量镜头；由于直推式学习从已知样本出发能对特定的未知样本进行学习和识别，最后在这个框架中提出了一种基于张量镜头的直推式支持张量机算法，它不仅保持了张量镜头所在的流形空间的本征结构，而且能够将训练集合外数据直接映射到流形子空间，同时充分利用未标记样本改善分类器的学习性能。

Base on the thinking on the above questions and the results from demestic and foreign relavent research, this paper makes an investigation into the leisure centers of research based scienced parkes, discussing their categories, space distribution as well as charateristcs and giving out tentatively the methodolgy of disigning and principle of assessing. Taking those theories conbined with view points from environmental psycology theory, field investigation on the development of the leisure centers of the software park of Wuhan Photoelectron Valley is studied to accomplish the deduction.
