[Bio-Recognize] ICA2000_reprint.doc

Description: 具有带通选择性的ICA算法可以改善对于带通时间序列的分离以及对于周期性脑功能响应信号的提取. 因此本文提出的方案可将被估计信号, 如:周期性响应信号以及具有平滑空间分布的脑功能激活区, 的先验特性以特征选择的方式加入ICA算法用以提高对此类信号的估计-with selective ICA algorithm can be improved for the band pass time series, as well as for the separation of brain function cyclical response signal extraction. Therefore this paper, the program can be estimated signals, such as : the cyclical response signal as well as smoothing the spatial distribution of activation of brain function, a priori properties Feature selection to join the ICA algorithm used to enhance the signal of such estimates

[matlab] YOLi_ICASSP05

Description: 本文提出一种用于独立成份分析(ICA)的特征选择滤波方案用于改善ICA算法对关键独立成份(SOI)的分离和提取,关键独立成份在其信号样本数据的空间分布上具有一定特征. 本文以平滑滤波为例,表明加入此类特征滤波的ICA算法可以改善对于视觉功能区等平滑图象信号的提取. 因此, 这种特征滤波技术在估计具有平滑特性的脑功能成像方面具有潜在的应用价值.-for Independent component analysis (ICA) feature selection filtering program for the improvement of ICA algorithm independent of the key ingredients (SOI), the separation and extraction, the key element in its independent signal sample data on the spatial distribution of certain characteristics. This paper smoothing filter as an example, table membership in such features filtering ICA algorithm can improve visual function areas smoothing image signal extraction. Therefore, this feature filtering technology is estimated at smoothing properties of brain imaging have potential value.

[Other] 降维与特征选择

Description: 在machine learning中，特征降维和特征选择是两个常见的概念，在应用machine learning来解决问题的论文中经常会出现。对于这两个概念，很多初学者可能不是很清楚他们的区别。很多人都以为特征降维和特征选择的目的都是使数据的维数降低，所以以为它们是一样的，曾经我也这么以为，这个概念上的误区也就导致了我后面对问题的认识不够深入。后来得到老师的指点才彻底搞清楚了两者的关系，现总结出来与大家分享。(Feature reduction and feature selection are two common concepts in machine learning, which often occur in papers that apply machine learning to solve problems. For these two concepts, many beginners may not be very clear about their differences. Many people think that the purpose of feature reduction and feature selection is to reduce the dimensionality of data, so they are the same. Once I thought so, the misunderstanding of concept led to the lack of in-depth understanding of the problem behind me. Then we got the guidance of the teacher to make clear the relationship between the two and share it with you.)
