Description: The tca package is a Matlab program that implements the tree-dependent
component analysis (TCA) algorithms that extends the independent
component analysis (ICA), where instead of looking for a linear transform
that makes the data components independent, we are looking for components
that can be best fitted in a tree structured graphical model. The TCA model
can be applied in any situation where the data can be assumed to have been
transformed by an unknown linear transformation. Platform: |

Description: 从因子分析的角度出发解决基因表达谱分析问题。为解决独立成分分析方法在求解过程中的不稳定性,提出一种基于选择性独立成分分析的DNA微阵列数据集成分类器。首先对基因表达水平的重构误差进行分析,选择部分重构误差较小的独立成分进行样本重构,然后基于重构后的样本同时训练多个支持向量机基分类器,最后选择部分分类正确率较高的基分类器进行最大投票以得到最终结果。在3个常用测试集上验证了本文设计方法的有效性。-This paper tries to deal with gene expression problem in view of factor analysis. In order to overcome the instability problem caused by performing independent component analysis, a DNA microarray data ensemble classifier based on selective independent component analysis is proposed. The reconstruction error of each gene is analyzed firstly and a part of independent components which contribute relatively small reconstruction errors are selected to reconstruct new samples. After that, several support vector machine base classifiers are trained simultaneously. Finally, the best base classifiers with high correct rates are selected to participate in the ensemble, using the majority voting method. Results on three publicly available microarray datasets show the feasibility and validity of the method proposed in this paper. Platform: |

Description: 独立成分分析
目前,独立成分分析(ICA)这门新的数据处理技术已得到了国内外学术界的普遍认可和广泛关注,并在不同的研究和应用领域开始发挥重要作用。ICA这一专业术语及其内涵,“鸡尾酒会”问题、脑电信号分离、通信系统的盲分离等ICA的典型应用问题,以及ICA中有关峭度、不动点算法等一系列基本概念,已为国内许多从事数据处理的科研工作者所熟悉。但是,要了解独立成分分析背后所隐含的重要应用背景与数学理论基础;把握ICA的应用范围及相应的各种限制;了解如何应用独立成分分析的思路,从而针对具体的专业应用问题提出更为合理的分析方法,这些更深层次的内容,可能并非通过阅读几篇综述文献或相关专业文献,或学习、分析和使用MATLAB工具包中的那些现成算法就能很好地掌握的。然而,目前国内仍然没有一本比较全面而深入的中文教材来供那些对ICA感兴趣的初学者和不同专业领域的研究人员做参考。这种状况下,翻译出版一本比较权威的ICA教材就显得很有必要。本书的英文版是国际上第一本对ICA这门新技术进行全面介绍的综合性专著,作者Aapo Hyv妑inen,Juha Karhunen和Erikki Oja为ICA方法的建立做出过重要贡献,并且一直活跃在ICA的相关研究领域。本书的内容主要取材于作者自己的研究小组所开展的-Independent component analysis
Currently, independent component analysis (ICA) which door the new data-processing technology has been widely recognized by domestic and foreign academic and attention, and different studies and applications play an important role began. ICA and its connotation of the terminology, "cocktail party" problem, EEG separation, communication systems for blind separation of a typical application of ICA, and ICA in the kurtosis, fixed point algorithms and a series of fundamental concepts, has been Many engage in data processing for the domestic workers are familiar with the research. However, independent component analysis to understand the importance of applications on the underlying mathematical background and theory grasp the application of ICA and the corresponding limitations know how to apply the idea of independent component analysis to specific application of a more professional reasonable methods of analysis, these deeper levels of content, may not be Platform: |
