FindOut: Finding Outliers in Very Large Datasets

Finding the rare instances or the outliers is important in many KDD (knowledge discovery and data-mining) applications, such as detecting credit card fraud or finding irregularities in gene expressions. Signal-processing techniques have been introduced to transform images for enhancement, filtering, restoration, analysis, and reconstruction. In this paper, we present a new method in which we apply signal-processing techniques to solve important problems in data mining. In particular, we introduce a novel deviation (or outlier) detection approach, termed FindOut, based on wavelet transform. The main idea in FindOut is to remove the clusters from the original data and then identify the outliers. Although previous research showed that such techniques may not be effective because of the nature of the clustering, FindOut can successfully identify outliers from large datasets. Experimental results on very large datasets are presented which show the efficiency and effectiveness of the proposed approach.

技术转移对我国制造业企业创新绩效的影响

分别对高新技术企业与一般工业企业、大型企业与中小型企业进行了对比分析，发现高新技术企业比一般工业企业更有吸收能力，而技术转移对中小企业的影响比大型企业大。对参与技术转移及未参与技术转移的制造业企业进行了比较研究，结果证明有技术转移行为的企业具有更优的创新绩效。     

Ranking Pages by Topology and Popularity within Web Sites

We compare two link analysis ranking methods of web pages in a site. The first, called Site Rank, is an adaptation of PageRank to the granularity of a web site and the second, called Popularity Rank, is based on the frequencies of user clicks on the outlinks in a page that are captured by navigation sessions of users through the web site. We ran experiments on artificially created web sites of different sizes and on two real data sets, employing the relative entropy to compare the distributions of the two ranking methods. For the real data sets we also employ a nonparametric measure, called Spearman's footrule, which we use to compare the top-ten web pages ranked by the two methods. Our main result is that the distributions of the Popularity Rank and Site Rank are surprisingly close to each other, implying that the topology of a web site is very instrumental in guiding users through the site. Thus, in practice, the Site Rank provides a reasonable first order approximation of the aggregate behaviour of users within a web site given by the Popularity Rank.

中国工程勘察设计咨询业产业整合的路径选择

产业是由具有相互联系、相互制约的若干组成部分结合在一起并且有特定动能的有机体,产业分工越合理,资金、人力资源和各种自然资源与物质资料在产业内发挥的功能越大;中国工程勘察设计业的产业结构“中间大,两头小”,产业内部资源分布极不合理;结构调整的最佳选择是以工程项目总承包和分包为分工协作的垂直一体化:分化重组中间的工程咨询单位,组建顶端的EPC工程公司,发展低端的专业咨询公司、事务所。
