	1	基于特征匹配的快速降维排序搜索方法显示文摘在大数据时代背景下,越来越多的用户或者企业将大量的数据上传至云端存储以便减轻本地存储的压力和获得高效的数据共享服务管理,由此可搜索加密技术应运而生,检索效率与保证数据安全一直是研究的热点。因此,本文提出一种基于特征匹配的快速降维排序搜索方法(DRFM)。通过提出的特征得分算法,创建每一篇文档的索引特征向量;通过提出的匹配得分算法,创建查询关键词的查询匹配向量。使用K-L变换算法对所有文档索引特征向量以及查询匹配向量进行降维,提高算法效率。理论分析与实验结果表明所提的方案高效且可行。	徐惠铁治欣舒莹	2022	计算机与现代化2022，，2：	0
	2	Detecting Three-Dimensional Associations in Large Data Set显示文摘The associations detection among variables in the large dataset is recently important due to the rapid growth rate of data.The interested associations can provide references for solving the problems such as dimension reduction and feature selection.Many methods have done on the associations detection of pairwise variables.The multi-dimensional variables,especially three-dimensional variables,is rarely studied.The relationships among them cannot be revealed by the detection of pairwise variables methods.A new method of Maximal three-dimensional information coefficient(MTDIC)is proposed which is able to indicate the associations of three-dimensional variables.The correlation coefficient is calculated from the three-dimensional mutual information.The World Health Organization(WHO)data and the Tara data are selected to evaluate their associations.The experiment is verified by comparing the coefficient results with the Distance correlation(Dcor).The accurate association strength is obtained by an iterative optimization procedure on sorting descending order of coefficients.The MTDIC performs better than the Dcor in generality and equitability properties.
