Accessibility of regional traffic in the worst-hit areas of Sichuan should be viewed with some concern. The difficulty of disaster relief work in May 12th Earthquake had showed unsubstantial traffic condition of the disaster area. Approach of weighted average travel time is adopted in this paper to calculate accessibility of 3 main traffic manners, i.e. highway, railway and aviation, and their integrative...
Biclustering the gene expressing data is an important task in bioinformatics. A parallel biclustering algorithm for gene expressing data is presented. The algorithm starts from the data sets containing pair of rows and columns of the data matrix, and gets the biclusters by gradually adding columns and rows on the data sets. A pruning technique is also proposed to reduce computing time. Experimental...
An important component of web personalization is to mine typical user profiles from the vast amount of historical data stored in access logs. A new clustering algorithm based on user transactions was proposed to provide personalized recommendation service for the websites. As an improvement on K-means algorithm, we got best cluster number and initial clustering centers automatically by competitive...
Determining the size of the World Wide Web is extremely difficult. The Web can be viewed as the largest data source available and presents a challenging task for effective design and access. One proposed Web mining approach to handling the problem of effective design and access is personalization. With personalization, Web access or the contents of a Web page are modified to better fit the desires...
